"After declining for about nine years, the crude birth rate (CBR) in Egypt increased from 1972 to 1979. This recent increase occurred despite increasing use of contraceptives....In order to understand the trend in marital fertility in Egypt, I have analyzed the trend in the probability of having a specific birth order in a specific period of time. In order to understand which factors are associated with large family size, I have studied the determinants of cumulative fertility measured by number of children ever born (CEB). A causal model of the determinants of cumulative fertility has been developed and tested....[It is concluded that] the fertility transition has already begun in Egypt. Expanding education and family planning services are the policies most likely to hasten the fertility transition in Egypt."

"This paper addresses the issue of the relationship of fertility between successive generations over the course of a 19th-century frontier fertility transition. Intergenerational event histories are used to explore the relationships between mothers' and daughters' completed family size. Results suggest that daughters' fertility levels are responsive to their mothers' relative fertility and age at marriage (as compared with mother's contemporaries). Effects of exposure to a number of younger siblings, controlling for cohort biases, are also examined. A multivariate proportional hazard analysis of daughter's age at marriage and parity-specific birth intervals demonstrates the direct and indirect effects of intergenerational fertility associations on fertility timing." Data are from the Mormon Historical Demography project's set of computerized family genealogies.

The purpose of this study is "to identify the various life stages of an individual in Bangladeshi culture, to describe the psychosexual development and gender role expectations in the different life stages, to relate these to sexual and reproductive behavior, and in addition, to suggest implications for policy." The data concern the life histories of 65 men and women in rural villages in Matlab thana and were collected during a 1978 anthropological survey. The first four chapters deal with cultural aspects of sex roles, sex socialization, and reproduction. Chapters 5 and 6 examine sex behavior at different ages. Chapters 7 through 11 are concerned with fertility, including family planning, communication, and sex education.

"This paper examines the relation between unmarried cohabitation and three important determinants of fertility--frequency of sexual intercourse, contraceptive practice, and the expectation to have a child within five years. Analyses based on data from the 1982 [U.S.] National Survey of Family Growth show that formerly married cohabitants are similar to married women with respect to these fertility determinants, but that never married cohabitants may have lower fertility in the short run because of extremely high levels of contraceptive practice. The paper also compares self-reported data on cohabitation with an inferred measure based on household composition."

The authors examine some of the factors indirectly affecting fertility in Sierra Leone and attempt to disentangle the complex causal relationships into direct and indirect effects. Data are from a fertility and family planning survey carried out in rural areas of Moyamba District in 1979, which covered some 2,000 women aged 15-49. "Information was collected on personal characteristics of the respondent and her husband, fertility behavior, socioeconomic and religious characteristics, family-size intentions, contraceptive use, and attitudes toward and knowledge of family planning."

"This is the sixth in a series of monographs which present results derived from the data collected in the 1980 National Population Census [for Papua New Guinea]." Earlier reports have dealt with urban boundary changes, urban spatial distribution, internal migration, mortality, and urbanization and urban migration; the present document is concerned with fertility. Attention is given to changes in fertility between 1966 and 1980, including lifetime fertility, current fertility, and various fertility estimates. Fertility patterns and differentials are also discussed.

Faculty of Social and Cultural Sciences Working Paper Series, No. 11, Nov 1986. 71 pp. Tilburg University, Faculty of Social and Cultural Sciences: Tilburg, Netherlands. In Eng.
"Total Fertility Rates [TFR] are given for male as well as female populations [of the Netherlands], decomposing these rates in terms of the Total Marital Fertility Rates, the Total Extra-Marital Fertility Rates and the effect of weighting by proportions married. Two-sex intensities and sex-ratios at birth are calculated." The analysis is for the period 1942-1984. The significance and uses of these two-sex rates as measurements of fertility are favorably assessed. It is found that "although the decrease in TFR has slowed down considerably after 1975, there are no indications of an increase as yet. Intensities in the marital as well as the extra-marital sub-populations are however increasing since about 1975. The shift of persons in childbearing ages from the married to the unmarried subpopulations offsets these increases leading to relatively steady levels of TFR. There is a negative relation between the sex-ratio at birth over the 1942-1984 time-span and age of mother as well as father at birth of the child."

"This study explores some aspects of the interrelationships between infant/child mortality and reproductive behavior among Ghanaian women, using data from the 1979 to 1980 Ghana Fertility Survey....There are substantial differences in infant/child mortality associated with mothers's age at birth, birth order, survivorship of the previous child, parent's education, current residence, region of residence, religion, and ethnic group of mother....Analysis of the effects of infant mortality on subsequent reproductive behavior using conventional life tables and the fate of the preceding two births approach indicates that the probability of a subsequent birth increases significantly following the death of the last child, largely owing to maternal physiological factors."

"Fertility remains high and stable throughout sub-Saharan Africa, and there is no certain evidence of any national fertility decline. The explanation is not solely lack of development or ineffectiveness of family planning programs; almost 20 years ago some countries were relatively well developed and had introduced national population programs. The explanation lies largely in a religious belief system and an accompanying social structure that have accorded both spiritual and economic rewards to high marital fertility. Because of the weakness of the conjugal link, men do not feel the full economic burden of their reproductive decisions, while women are ultimately so dependent on their children that they have good reason to fear having too few. This essay explores the context of high African fertility as well as signs of destabilization in this high-fertility system on both the individual and national level."

"This article traces major trends in the population of Taiwan's reproductive behavior from 1961 until 1984-85, when the net reproduction rate was below 1.0. For 1961-84 about 35 percent of the fertility decline in Taiwan was due to declining nuptiality. Major declines in fertility at ages over 30, a major factor in the first 15 years, have brought rates at the older ages close to zero. The practice of contraception has almost reached saturation levels, with high use rates in all major population strata. Sterilization has replaced the IUD as the modal method and an increasing majority of the couples now begin practicing contraception to space births. The 'KAP-gap' has virtually disappeared. While preferred family size continues to fall, social differentials in preferences persist. However, few couples are satisfied with only one child. Taiwan's family planning program has attained its demographic objectives of going from high to low birth and death rates, but its social welfare functions continue."

"The aim of this paper is to analyze empirically the causal relationship, if any, between infant mortality and fertility in thirty-five developing countries." The focus is on possible relationships between the infant mortality rate and the fertility rate. "The hypothesis that infant mortality causes fertility is tested. The possibility of a 'reverse causation' is also analyzed. A one-sided distributed lag test as proposed by Granger...is employed." The results are analyzed in light of several versions of the mortality-fertility proposition, including demographic transition theory, choice theory, Ricardian theory, and the modern economic theory of population.

"In many Indian societies couples have consistently reported strong preferences for sons. However, these preferences are not always reflected in either contraceptive use or fertility. Previous studies refer mainly to the period 1961-1970, when contraceptive use was minimal, there was little evidence of conscious control among couples, and the majority had large families. This paper, using samples of rural and urban women interviewed during 1979-1980, shows that the sex of previous children at various attained parities has a significant effect on subsequent fertility. We conclude that son preference now has an effect because family size has decreased and contraceptive use has increases. The disappearance of sex preference would reduce overall fertility modestly."

This is one in a series of papers concerning fertility levels and trends in selected countries in the ESCAP region. The present report concerns Sri Lanka; the analysis covers the period 1962-1980. "Changes in fertility at the district level are decomposed in terms of two components, the proportions married and the fertility of married couples. This could only be done in a country with a refined system of vital statistics and a series of censuses of high quality." The impact of nuptiality changes on fertility is assessed. Data are from the 1963, 1971, and 1981 censuses and from the vital registration system.

"This report examines the relationship between the trend toward delayed childbearing and a variety of socioeconomic phenomena that have paralleled the temporal variations in U.S. fertility. The basic hypothesis motivating the analysis is that, over time, men and women have become more homogeneous with respect to market earnings potential at the time of marriage." Data are from the National Longitudinal Survey. "The results of the microdata analysis show that both the age at first birth and female labor force participation after marriage are positively related to the degree of sexual equality in earnings at marriage. However, the time series analysis suggests that the postponement of childbearing and increased female employment characterizing the last two decades have occurred despite a fairly sharp decrease in the average earnings of women relative to men at marriage."

"Libya is one of the Middle East nations with very high fertility and data from 1973 suggest the presence of a natural fertility regime marked by the absence of fertility limitation within marriage. Analysis of paternity data by occupation, however, identifies major differences in the level and pattern of childbearing. The Libyan data are compared with fertility and paternity data from an American frontier population to demonstrate that the general patterns observed are consistent with other natural fertility populations, while selected occupational groups may limit family size."

Population Studies Center Research Report, No. 85-77, Apr 1985. 16 pp. University of Michigan, Population Studies Center: Ann Arbor, Michigan. In Eng.
Lessons from the World Fertility Survey (WFS) concerning the consequences of socioeconomic position for reproductive behavior are examined using comparative studies of WFS data. The authors find that "the WFS has provided the data that have allowed investigators to: (1) confirm the importance of socioeconomic indicators, especially education, for reproductive behavior in a wide variety of social settings; [and] (2) establish the existence of meaningful variability between social settings in the effects of these indicators....We comment on the implications of the patterns observed within and between countries for two explanations of the reproductive consequences of socioeconomic position, one stressing the material bases of that position and the other emphasizing the ideas, values, and attitudes associated with it....We argue that the evidence does not favor the ideational over the structural explanation, but supports them both."

"This study investigates the effects of three aspects of women's status on the fertility of Thai women. These include marriage arrangements, patterns of intrafamilial decision making, and women's human capital skills and economic activities. The analysis is based on data collected in the 1979 Asian Marriage Survey in Thailand. A multiple classification analysis is used to investigate fertility beyond the second birth. Survival tables and multivariate proportional hazards models are used to study differentials in the rate at which women with two children have a third birth. We test the hypotheses that the effects of these women's status variables on fertility are (1) greater in an urban setting than in a rural setting, and (2) increased after the Thai reproductive revolution. We identify cultural differences in fertility decisions between ethnic Thais (who have a bilateral kinship system with uxorilocal residence) and Thai-Chinese (who have a patrilineal, virilocal kinship system)."

Data for 81 countries are used to develop econometric models in order to test a hypothesis that links social security programs and fertility. "By controlling for economic development and testing the model at different points in time, the social security variable was found to be causally linked to subsequent fertility levels as well as fertility levels being causally linked to subsequent social security expenditures. Furthermore, the appropriate response lag was identified and various nonlinear functional forms were utilized to control for economic development. Finally, a Chow test was employed to show the existence of structural change between the developed and less developed nations."

"Despite their great wealth, elite subpopulations in Western Europe experienced long-run demographic contraction. This article argues that their numerical decline was related to their determination to maintain high and undiminished standards of living for themselves and their heirs. Since the proper endowment of more than a small number of elite children threatened the material basis of family status, reproductively active married couples tried to restrict effective replacement (on average) to two married children. Since a large fraction of elite couples (15 to 30 percent) were childless, aggregate demographic decline (in a closed population) was inevitable. Currently, the world's wealthiest countries are also faced with impending demographic contraction. Parallels are drawn between the status-protecting strategies of traditional elites and those of ordinary couples in modern developed populations, whose high-cost, high-risk children have more in common with those raised by elite families than with children in traditional agrarian economies whose labor and insurance value secured, rather than threatened, their parents' status."

Fertility trends in Estonia, USSR, over the past 300 years are reviewed. Attention is paid to developments since 1900, particularly to the period since World War II, when a substantial migrant population came to Estonia. The author notes that the indigenous population reached a low level of fertility before the migrant population. Recent fluctuations in fertility among both populations are described; it is noted that the fertility of the indigenous population is currently at a replacement level.

The reproductive revolution that has occurred in Thailand in recent years is reviewed. The authors' stated goal is "to present a comprehensive study of this revolution, documenting the nature and extent of the changes that have taken place and explaining them in demographic, socioeconomic, and cultural terms, including an assessment of the role of organized family-planning programs." Both qualitative and quantitative methods are used to examine the proximate determinants of reproductive change. "The authors begin by placing Thailand in comparative perspective within the contemporary Third World context and then detail its population growth and distribution, land availability, and other important social and cultural factors. They go on to explore recent trends in fertility, family size, and demand for children, taking into account desired family size, gender preferences, and religious differentials....The authors conclude by considering the practical and theoretical significance of the Thai experience to Third World population science and policy."

"This paper has two objectives. The first is to present a new, comprehensive set of estimates of the seasonal patterns in births. The paper adopts a simple methodology that is then applied to a large variety of countries and time periods. Our estimates show that two main seasonal patterns emerge often (the United States pattern and the European pattern), that these patterns do not occur according to a simple rule across hemispheres, and that the amount of seasonality does not consistently increase or decrease over time. The second purpose of the paper is to examine the consistency of our results with proposed explanations of birth seasonality. We conclude that cross country comparisons of birth seasonality allow us to eliminate only a few of the interesting explanations of birth seasonality....Closer examination reveals that there is a consistent pattern to the type of seasonal fluctuations displayed by a particular country. This pattern strongly suggests the effects of weather as an important determinant of birth seasonality."

The author attempts to reintegrate the sociological and economic approaches to the analysis of fertility using a model of joint economic and cultural dynamics. It is argued that "the ingredients of [the] New Home Economic [approach]...are non-redundant, yet insufficient; the classics in both economics and sociology do provide workable and systematized theories about mechanisms of preference formation; attempts to measure cultural change in preferences, values and ideational goals...have come up with patterning worthy of further consideration and integration; [and] the perception of the alleged shortcomings of the other social sciences with respect to developing systematic usable knowledge is connected with the intellectual closure of a branch of contemporary economics to literature in adjacent fields." The main focus is on Europe, excluding Eastern Europe.

This study is concerned with the problem of fertility in sub-Saharan Africa. The author presents "a summary of the findings that establish a link between the particular nature of sub-Saharan preventive checks on reproduction and various aspects of the ecosystem and forms of social organization. Here, we shall draw heavily on cross-cultural analyses of associations between organizational variables. The aim of this section is to establish the organizational basis from which a transition is supposed to take off. The following sections deal with changes in this system produced by exogenous factors, such as the introduction of cash crops, agricultural and industrial wage labour and migration, the growth of the urban sectors, the expansion of formal education and the cultural influences of Christianity and Islam. More specifically, we shall argue that the reproductive system of black Africa is adapting in an uneven way, with some ingredients changing at a rapid pace, while others show a high degree of resistance....The data for this exercise stem largely from [official] censuses and demographic surveys."

The impact of selected proximate determinants of fertility on the total fertility rate (TFR) in Taiwan is examined using data from a 1985 induced abortion prevalence survey of 12,516 married women aged 15-49. "Bongaarts' model of proximate determinants of fertility is applied to the survey data to analyze the relationships among total fertility rate, total fecundity, and the indices of the proximate determinants [of] non-marriage, contraception, induced abortion, and lactation." It is found that the index of contraception and the proportion married had a significant effect on TFR, while induced abortion and lactational infecundability had little effect. Differences by urban or rural residence are noted.

Changes in sexual activity, contraception, and fertility in the Dutch-speaking part of Belgium are analyzed using data from the NEGO fertility surveys, including the NEGO IV survey carried out in the early 1980s. The results show that for "women in Flanders born between 1931 and 1962...premarital sexual intercourse has become almost general and that the age at the onset of sexual intercourse is steadily declining. Until the 1970s in spite of the improving contraceptive behaviour of youngsters, the number of women experiencing premarital pregnancy increased and first conceptions occurred at an increasingly younger age. The 1970s marked a turning-point: fewer women became pregnant before marriage or in adolescence. From that time, the contraceptive revolution kept pace with the sexual revolution."

In Ger. with sum. in Eng; Fre.
"A simple model for age-specific marital fertility rates is presented and empirically checked [using data for the Federal Republic of Germany]. By using this model it is shown that--as a rule--age-specific marital fertility rates are not independent of changes in marriage behaviour. Only if marriage frequencies in all age groups change by the same percentage will age-specific marital fertility rates remain unaffected by this change. The 1972/74 and 1980/83 marriage tables were used in order to be able to make statements about the actual change in marriage frequencies. These tables reveal that the marriage frequencies decreased altogether from 1972/74 to 1980/83 and that the average age at marriage increased simultaneously. By using the simulation calculation it is shown that--ceteris paribus--the age-specific marital fertility rates should, in almost all age groups, have...increased (reaching top values of more than fifty percent) as a consequence of this actual change in marriage behaviour."

"The analysis of annual age-specific fertility rates in Finland over more than 200 years reveals the existence of a significant early fertility decline at the end of the eighteenth century preceding the secular decline that started around 1910. A reconstruction of age-specific proportions married by a simulation model based on Coale's marriage model indicates that the mean age at marriage increased and the proportion of ever-marrying decreased substantially during the period of the early fertility decline. A modification of the index of family limitation applied under certain assumptions to overall fertility rates also indicates that fertility was essentially natural until 1910. Cross-lagged correlation analysis shows that infant mortality does not influence subsequent fertility in the premodern period. Finally, a number of socio-economic indicators are related to fertility, and conclusions are drawn from the Finnish case about several hypotheses in the field of demographic transition."

"Data from the 1900 U.S. Census of Population show that fertility in Los Angeles, California, declined by more than 50 per cent between 1880 and 1900. Women's mean age at first marriage, which rose by approximately three years, contributed to the decline, but change in marital fertility was more important than change in nuptiality. Although the fertility of in-migrating U.S.-born women was lower than that of California-born women, the decline was not explained by in-migration. The emergence of a class differential in fertility, with couples of higher status having fewer children than those of lower status, and the simultaneous weakening of class differentials in secondary-school attendance, together suggest that the rise of universal secondary schooling probably did not account for the marital fertility decline experienced in middle- and upper-status families."

"This paper specifies and tests a multilevel theory of age at first birth, specific to less developed countries. The data are at two levels. At the micro level, the data come from 30 World Fertility Surveys (WFSs). At the macro level, the data include global measures derived from international data compendia, and information aggregated from the individual WFSs. The purpose of the theory is to explain how age at first birth (AFB) varies from one country to the next. We specify a micro model in which AFB is a function of wife's education...and type of place of childhood residence....At the country level, the focus is on variability in the coefficients of this model....We examine the implications of cross-national variability in the opportunities for, and alternatives to, marriage (or union) in a multilevel model of AFB. The major task of the paper is to sketch the rationale for this model, which modifies and adapts a framework proposed by Dixon (1971), and to explore its empirical validity in 30 WFS countries."

"Easterlin's synthesis of the behavioral and biological factors affecting fertility can be condensed into two central concepts: the demand for births, taking contraceptive costs and the likelihood of child survival into account, and a ceiling or upper bound on lifetime fertility, the product of length of exposure to the risk of childbearing and underlying fecundity. The econometric method known as 'switching regression' is well suited to the analysis of lifetime fertility in the presence of a supply constraint. This paper applies the switching regression methodology in an investigation of fertility in Sri Lanka and Colombia."

The author analyzes the reproductive behavior of Turkish immigrants in the Federal Republic of Germany. He argues against the assumption that reproductive behavior is primarily the result of socialization processes. "After discussing the special problems associated with the use of index numbers in the field of population statistics for the analysis of migration-conditioned changes in the reproductive behaviour, results are replicated on the correlation between the housing context and the number of children using individual data taken from 520 Turkish migrant families." It is found that "the (minimally different) context opportunities of the new (recipient) society do not have a differential effect on the reproductive behaviour accounting for the number of children."

Explanations for continued low levels of fertility among U.S. women are examined, with attention to studies concerning actual and opportunity costs of children as well as the implications of children for mothers' market and nonmarket employment. The author then argues that "women limit their fertility or remain childless because of the largely symbolic significance of childbearing for them and their lifestyles" and that this significance is related to a woman's views about male-female equality and the role of women in society. Illustrations are drawn from the 1985 NORC Survey.

"Fertility in the People's Republic of China has recently experienced a rapid decline. China's success has been hailed by some as representing an 'induced fertility transition.' Some have argued that the major factor has been the government's birth planning policy, and not the socioeconomic factors instrumental in fertility declines of other countries. Tien...observed, however, that the variability among China's subregions suggests that areas experiencing the greatest reductions in fertility may also be characterized by 'profound changes in socioeconomic structure.' This paper attempts to widen the discussion by examining relationships between socioeconomic development, family planning, and fertility among the 28 subregions of China around 1982."

"Fertility exposure analysis was developed recently by Hobcraft and Little in order to evaluate the relative importance of the various proximate determinants upon levels of current fertility. In the present paper we extend the analysis to the study of changes in fertility between two cross-sectional surveys. We show how to express fertility change as a product of terms which represent changes in the proximate determinants. The model of change is adapted to a log-linear framework, in which the proximate determinants on the one hand, and socio-economic variables such as education, on the other, are considered together. A few simplifications of the method are also suggested so that fewer demands are made on data. The model and its possible interpretations are illustrated with pairs of surveys from Pakistan and Mexico. In each pair, one survey was part of the WFS programme and the other was very similar but conducted five years later."

"Analysis of data from the Guyana Fertility Survey on the trends and covariates of age at first birth among various birth cohors of women ever in union indicates that an early entry into union is associated with young age at first birth and higher number of children born. Multivariate analysis showed that women with higher education, urban residence, and entry into union at age 20 or older among younger cohorts experienced lower risks for first birth compared to others, and that young women are delaying their first birth for longer durations than older women. Work status of women before first birth and the starting age of union seem to be the two major contributory factors for age at first birth. Noticeably, the role of education has changed and is now more significant among younger cohorts than among older ones for first birth timing."

The authors present a new set of estimated vital rates for India, specifically "the total fertility rate (TFR) and crude birth rate (CBR) for all of India, her major states, and urban and rural sub-divisions of those states for both 1971 and 1981." The estimates were prepared using regression methods developed by Palmore. The new estimates are compared with previous estimates using other techniques. The authors conclude that the "new estimates probably provide a reasonably accurate picture of the current fertility situation in India."

This report, translated from the original Spanish, presents a survey of the literature on the socioeconomic determinants of fertility in Mexico. Following a general introduction, the author discusses the literature dealing with relationships among economic development, social change, and fertility, with separate consideration of studies using census and vital statistics data and those using survey data. The next chapter examines fertility and individual socioeconomic characteristics. A third chapter deals with collective mediating mechanisms, defined by the author as studies that focus on individual reproductive behavior without touching on the usual intermediate variables. The author concludes that certain variables, such as urban residence, higher educational status, female economic activity, and relatively higher income, consistently appear linked to lower fertility.

The study is concerned with the cultural and economic factors affecting fertility in Europe (excluding Eastern Europe). "The underlying argument of this essay is that the factors which determine the importance to lifestyle of producing children are those which arise from the religious character of the relationship between individual and society." The author suggests that religion does not lose its force during the process of modernization but rather remains the driving force underlying the belief system of society and its institutions. Consideration is given to the relative importance of Christian fundamentalism and conventionalism regarding fertility, and to the effect on fertility of expectations of future income and lifestyle changes.

"The main objective of the study is to examine the present levels of fertility among different socioeconomic and religious groups [in northern India] and to examine some of the sociological correlates of fertility behaviour among the rural communities of Punjab and Haryana which are undergoing rapid economic transformation. The uniqueness of the study lies in highlighting the hitherto neglected area of intra-village and inter-village variations and providing explanations for these variations in observed differentials in fertility behaviour. A significant finding of the study is that land-owners have [fewer] births as compared to landless due to the fear of downward mobility and fragmentation of land holdings. Caste status and family structure has been found to be another important factor indicating variations in fertility. Inter-village variations in fertility are quite significant and they seem closely related to the level of socio-economic development of the villages indicating thereby the key role of socio-economic development in the reduction of fertility."

In this context, the suggested model has been modified for applying it to an empirical distribution. A method for estimating some of the parameters of the model is given."

"A striking peculiarity of American demographic history is its comparatively early decline in fertility. Although some of the decrease before the Civil War may be attributed to later and less universal marriage, marital fertility also fell. Past scholarship on the subject has focused on alternative explanations and statistical approaches to cross-sectional variations in the child-woman ratio. After showing the inherent limitations of this approach, particularly at the level of states, this article draws on the findings of historians of political behavior and women's activities to suggest that the understanding of the early decline in marital fertility in the United States may be most profitably pursued through the study of the fertility behavior and values of the principal action-groups of antebellum America: religious, ethnic, and economic. Both the motivations for, and possibly the techniques of, family limitation were transmitted and sustained, this hypothesis contends, through membership and participation in these groups."

Five hypotheses related to fertility are tested using data on Native Indians from the Canadian censuses of 1961, 1971, and 1981. They are "(1) the modernity thesis of fertility decline; (2) the fertility-enhancing effect of modernization thesis; (3) the characteristics-assimilation hypothesis of fertility; (4) the minority-status insecurities hypothesis; and (5) the pronatalist subculture thesis. Results from descriptive and multivariate analyses provide strong support for Hypotheses (1), (2), (3), and (5), but no support for Hypothesis (4)." The author concludes that traditional pro-natalist influences are likely to result in the persistence of high fertility for a considerable time despite the effects of modernization.

In this paper an alternative adjustment to stable birth rate estimates using the framework of the generalized stable population equations is derived, and the close agreement between the new adjustment and that given by Coale is illustrated for some African countries. A simpler, more robust estimate of birthrate is also deduced from Coale's adjusted birth rate."

"The economic theory of population growth applies the opportunity cost approach to the fertility decision. Variations and differentials in fertility are caused by the available resources and relative prices or by the relative production costs of child services. Pure changes in real income raise the demand for children or the total amount spent on children. If relative prices or production costs and real income are affected together the effect on fertility requires separate consideration."

"The performance of formal demographic feedback models like Ronald Lee's provide a test of whether theories of endogenous fertility adjustment like Richard Easterlin's can explain the cyclic swings in U.S. and other births that they were put forward to explain. This paper shows how the specification of a demographic feedback model determines its ability to sustain cycles of a given period and amplitude observed in data. Only a few of the many versions of Easterlin-style theories imply formal models which do not prove capable of matching U.S. targets, and then only by narrow margins. The general methods presented here are suitable for a broad investigation of the possible role of age-specific feedback in the diversity of more and less cyclic patterns in birth series in the developed world."

"A convenient measure of fecundability is time (number of menstrual cycles) required to achieve pregnancy. Couples attempting pregnancy are heterogeneous in their per-cycle probability of success. If success probabilities vary among couples according to a beta distribution, then cycles to pregnancy will have a beta-geometric distribution....The likelihood ratio test can thus be employed in studies of exposures that may impair fecundability. Covariates are incorporated in a natural way. The model is illustrated by applying it to data on cycles to pregnancy in smokers and nonsmokers, with adjustment for covariates."

The relationship between fertility demand and work supply among married women in Hong Kong is explored using data from a 10 percent sample of the 1976 by-census. The results indicate that the presence of young children encourages women to seek work but of the kind they can do at home. The existence of this kind of work is also shown to lead to increased fertility.

The author postulates that the socialist system in China has created conditions advantageous to a rapid fertility decline and that the highly centralized system facilitates the implementation of China's family planning policy. The data used to illustrate this view are from China's 1982 census and the 1-in-1,000 fertility survey. The author is critical of opposition to China's current family planning policy.

The author examines changes in the total fertility rate and parity progression ratios in China using data from the 1983 1-in-1,000 fertility survey. Particular attention is given to fluctuations in the total fertility rate prior to and since the implementation of China's current population policy. A decline in parity progression ratios since the 1970s is noted, and reasons for these changes are discussed.

The author critically examines the Coale-Trussell marital fertility model, asserting that it is not applicable to the situation in which the marital fertility rate decreases rapidly, such as in the case of China. The limitations of the Coale-Trussell model are outlined and a new model is developed, which is applicable to situations of both rapidly decreasing and moderately decreasing marital fertility rates. Empirical results drawn from an analysis of U.N. data for 1965 and 1981 indicate the greater accuracy and flexibility of the new model as compared with the Coale-Trussell model.

"This study focuses on the effects of ethno-religiosity on fertility and contraceptive behavior in the plural society of Sri Lanka. The six ethno-religious groups...are examined using data from the 1982 Sri Lanka Contraceptive Prevalence Survey. The analysis clearly shows that ethno-religious differences in fertility and contraceptive use are substantial. Within each group, however, socio-economic status is negatively associated with fertility." Findings specific to each of the groups studied are also discussed.

Data from sample surveys conducted between 1978 and 1981 are used to examine the fertility of women in second and subsequent marriages in the USSR. The results indicate that women up to age 25 who have been married more than once have higher fertility than women in a first marriage. However, total fertility is higher for women in uninterrupted marriages. The analysis is presented separately for various cohorts and for socioeconomic characteristics such as educational status and rural or urban residence.

"This study focuses on the determinants of migrant-nonmigrant fertility differentials in Taiwan with particular attention to rural-to-urban migrants. A socioeconomic model is developed in which the fertility determinants are classified into four broad categories: age characteristics, migration status, background characteristics, and current characteristics. The model is evaluated by analyzing data from a large and representative sample of [3,816] Taiwanese wives of childbearing age in 1980 through the use of multiple regression and multiple classification analysis. The fertility of migrants moving from rural to urban area lies in between that of nonmigrants at the place of origin and destination. After adjustment for age or marriage duration and education, the differentials become smaller but still exist. However, the differentials are negligible after further adjustment for current socioeconomic characteristics."

The author presents a critique of an article by David Lam on the relationship between population growth and income distribution. The focus is on Lam's claim that given certain conditions of mobility across income groups, "an increase in the fertility of the poor will unambiguously increase the percent poor in the steady state." It is argued that the mobility condition Lam sets forth "is not sufficient to predict the rise or fall of the percent poor in the steady state as a result of an increase in the fertility of the poor."

Ethnic variations in fertility levels and trends in Malaysia are analyzed using data from official sources, including the 1980 census. "All ethnic groups in Malaysia have contributed to this modern demographic transition but the rate of change has been most rapid for Chinese and Indians, Malay fertility having reached a plateau in the early 1980s. The effect of age structure, marital patterns and marital fertility (by parity) on the fertility declines for each ethnic community are analysed. Continuation of current trends would lead to replacement-level fertility for Malaysian Chinese and Indians by the year 2000. Malay fertility is likely to continue to decline but at a more moderate pace."

The authors focus on the question of "whether the kinds of motivation necessary to prevent early pregnancy vary by race in the United States and might therefore explain race differences in early childbearing. It is our hypothesis that they do. The occupational, educational, and marriage opportunities of black teenagers and their family backgrounds are quite different from those of white teenagers. To the extent that these factors differ by race, we hypothesize that rates of adolescent fertility will also vary by race." The authors review the literature on adolescent sex information and attitudes and on birth control and abortion services for adolescents. In addition, they examine the available literature and data on the relationships among adolescent fertility and education, employment, and marriage.

Fertility differentials in the United Kingdom are analyzed using data from the Family Formation Survey of 1976. "Variables associated with the couple's housing history and the wife's employment career are becoming more strongly associated with demographic differentials among younger cohorts than traditionally-based ones such as religion or region of residence. Cluster analysis techniques show which groups of family formation variables are strongly associated with particular types of non-demographic ones, and a natural grouping of explanatory variables is derived. The implications of these conclusions for data collection in demographic surveys are discussed."

A comparative analysis of adolescent fertility in Hungary is presented. It is noted that, in comparison to 29 other developed countries, the fertility rate of Hungarian women under age 18 is exceeded only by that of black Americans. Factors related to the high rate of adolescent fertility in Hungary include the high proportion of married women aged 15-19, induced abortion, agricultural employment, conservative attitudes toward sexuality, pronatalist policies, high rates of adolescent economic activity, high alcohol consumption levels, and lack of contraceptive knowledge among the young.

This is one in a series of publications dealing with the relationship between ethnicity and fertility in the countries of Southeastern Asia. The present study concerns Thailand. The data are for 858 Thai, 837 Chinese, 838 Thai Muslim, and 587 Southern Thai Muslim couples interviewed in a sample survey. Attention is paid to differences in contraceptive usage as well as to fertility differentials. The results indicate that "ethnicity is unquestionably a significant variable in the study of fertility and family planning in Thailand. Ethnic groups significantly differ from one another not only in the level of fertility and use of effective contraception but also in the variables that significantly affect their fertility and contraceptive behaviour. Population policies and programmes must therefore be carefully formulated and designed for each ethnic group."

"This paper re-examines the basis for Victorian fears of 'race suicide'--the differential fertility of immigrant women, native-born women of foreign parentage, and native-born women of native parentage [in the United States]. The analysis is based upon the cumulative fertility reported by women in the 1900 Public Use Sample, a national random sample of households drawn from the federal census, which includes information on over 100,000 individuals. Our work reports fertility differentials around the turn of the century and explores the determinants of contrasting levels of childbearing." The authors compare their results to those of previous studies and discuss the significance of regional differences and marital status in the study of fertility differentials around the turn of the century.

"This article examines the effects of English proficiency and female education on cumulative and recent fertility within the Mexican-origin population in the U.S. To ascertain whether the cultural or the human capital aspects of linguistic variables have the greater salience for fertility behavior, fertility patterns of bilingual women are compared with those of monolingual women speaking English or Spanish. Using the 1980 U.S. Census 5 percent Public Use Microdata Sample for ever-married Mexican-origin women aged 15-44, we find that for almost all age cohorts, the effects of English proficiency are negative and increase with rising education. The strength of the interaction is greater in younger age groups. Greater English proficiency is also associated with a more negative impact of education for native- than foreign-born women. Overall, the influence of 'opportunity cost', as opposed to cultural factors, is more important in shaping the fertility behavior of these women."

"A multivariate analysis of the 1984 Quality of Life-Survey, which was held among Turkish and Moroccan heads of households in the Netherlands, shows that their fertility is affected by factors concerning their native country as well as by some aspects of life in the Netherlands. A low current number of children is associated with a higher education in the native country, an urban background and no strong commitment to Islam. In addition, the marital status at immigration and the nationality of the woman also show a particular correlation with the fertility. Some socio-cultural characteristics such as the woman's work and house-ownership also have a certain association with the family size." The likelihood of further declines in fertility among Turks and Moroccans living in the Netherlands is discussed.

This correction may be important in settings of high induced abortion incidence. The method is then applied to the data of the Italian region of Lombardy. The results obtained are compared to those obtained with previous correction methods, and it is concluded that the present method is useful and appropriate when data on induced and spontaneous abortions are available by gestational age."

Logit analysis is used to examine the impact of motivational factors (desire for a child, age, parity, presence of children from a previous marriage) and economic/informational access factors (income, education, race, ethnicity) on infertility service utilization. Results indicate that the decision to use infertility services is a complex one that is affected by issues reflecting access to and motivation for service utilization."

Data obtained from a 1970 national medical and demographic survey are used to determine the effects of venereal disease (VD) on fertility in Teso and Ankole, two rural areas in Uganda. "Hazard models are used to estimate the effect of VD on fertility. The technique proposed uses event-history data which include, information about the prevalence of VD and estimates of fertility for VD and non VD women given age and/or marriage duration....This technique indicates that the impact of VD and the overall reduction in fertility is by all accounts higher for Teso than for Ankole....It is suggested that the age data provide a substantially truer picture of the estimates of the proportion sterile (or the proportionate reduction in fertility) given VD than do marriage duration based data."

"This article investigates the legal aspects of women's access to health care and family planning in Swaziland. First, the background to health care and family planning is discussed, including health care facilities that are available, the extent of contraceptive use and attitudes toward contraceptives, the problem of 'backstreet' or unauthorized abortions, and sterilization for medical reasons and for fertility regulation....It is concluded that the ambiguity of the law--and the divergence of law and practice in those areas where the law is relatively certain--affect women's health adversely by restricting their access to health and family planning. Finally, the question is raised as to whether legislative intervention is possible in a society molded by strong traditions that reflect disapproval of modern contraceptive methods."

This paper is concerned with the effects of family planning on morbidity and mortality in women and children. "Rather than attempt to establish the relative importance of child spacing as a cause of decreases in mortality, this paper takes as its starting point that there is a connection, and presents some possible causal mechanisms which explain how short birth intervals and child mortality could be related. In addition the most frequently cited hypotheses--maternal depletion and sibling competition--a third is examined--birth crowding which, it is suggested, influences the pattern of the transmission of infectious diseases and, in turn, mortality....The final section combines parity-specific data on maternal mortality with evidence of changes in fertility patterns brought about by family planning to assess how successful we can hope to be in reducing through birth control the number of women who die in childbirth."

"Life-table estimates indicate that one-quarter of U.S. women intend no more births by age 25, one-half by age 27, and three-quarters by age 30. The resulting long period at risk of unwanted fertility is argued to be an important underlying dimension of the revolution in attitudes to and practice of sterilization. Life-table estimates are then considered of the timing of sterilization after the last wanted birth. Almost one-quarter of all couples select sterilization within the first year after they have had the number of children they desire. Recent experience would imply that four-fifths of all couples will eventually use contraceptive sterilization. In order to examine the determinants of men's and women's sterilization, logistic regression is used with a polytomous dependent variable: sterilization of the woman, sterilization of the man, or no sterilization within four years of the last wanted birth. Covariates considered are age and parity at last wanted birth, year and duration of marriage at last wanted birth, wife's and husband's education, wife's and husband's religion, whether residence is in a central city, region, pill-use history and timing-failure histories before the last wanted birth, and unwanted birth. Large and significant effects are found for most of these variables, and these effects change in interpretable ways between early innovative behaviour and sterilization during the most recent period when it was widely accepted."

The authors investigate the determinants of contraceptive method choice in Thailand, primarily using data from the 1984 national contraceptive prevalence survey. Multivariate analysis is used with three categories of contraceptive choice as the dependent variable and age, urban or rural residence, education, employment status, parity, and a constructed variable representing region, religion, and language as the independent variables. Regression results are described in the text and summarized in tables. Among the findings, the authors note that "Moslems and Southern Thais are continuing to use traditional methods (withdrawal in particular) or no method rather than switching to modern methods....Another subgroup that appears to be resisting modern methods is the women with no education....[At the same time,] by 1984 there were no differences between Bangkok and other urban areas, and between Bangkok and rural areas in the proportion of women using the modern methods. The absence of use of coital methods in rural areas is indicative of the strength of the government programs in providing effective non-coital methods...."

"This paper discusses the main rationale for government interest in the provision of contraceptive technology through voluntary family planning programs in less developed countries: that of enhancing economic development. The discussion is organized under headings that identify two distinct if interrelated functions governments aim to perform in this domain: that of promoter of economic growth and that of provider of human welfare. The first function rests on macroeconomic arguments that suggest that slowing aggregate rates of demographic expansion will accelerate economic growth. The second function invokes benefits captured directly by the persons and their families who use the services offered by family planning programs. A concluding section comments on the possible need for government to set the stage for success in performing these functions by acting as an engineer of social change."

The author examines the lessons learned from over two decades of federal funding for family planning activities in the United States, with particular reference to the relative merits of categorical and block grants. In view of fiscal and political uncertainties, the author suggests that the safest way to attempt to meet unmet needs for family planning is through a comprehensive approach involving categorical funding.

The author asserts that developing an integrated family planning and health program in Bangladesh in an atmosphere of crisis concerning the need to control population growth has had a negative impact on the quality of health services provided. It is suggested that the use of sterilization incentives and the need to meet sterilization targets has undermined people's access to and use of primary health care services. "Findings from three studies, undertaken between 1978 and 1983, support the argument that despite international concern with preventive and promotive primary health care, simultaneous support for and emphasis on population control inhibits meeting the goals of a broad-based rural primary health care service."

"This study analyzes the fertility characteristics and the practise of contraceptive methods among married women aged 15-49 living in Izmit [Turkey] urban area. While the average pregnancies and the number of living children are lower than the average for overall Turkey, the use of contraceptive methods [is] found to be higher. Only [one third] of the women exposed use traditional methods. No significant relation is found between education level or number of living [children] and use of contraceptive methods. 66.5% of all women agree that due to medical or social reasons, legal abortions must be made in hospitals."

The authors examine causes of the declining rate of population growth among the Hutterites of North America. Data are from medical records containing contraceptive information obtained in 1985 concerning 48 Hutterite women. The results suggest that Hutterites are currently using contraception and that "12.5% of the women have used oral contraceptives and/or IUDs. An additional 25% have had a tubal ligation and/or a hysterectomy, meaning that over one third of the sample has made use of some form of birth control."

This is the report of the Working Group on Family Planning Effectiveness, set up by the National Research Council's Committee on Population, to prepare a scientific assessment of family planning programs in the developing world. It consists of 28 papers by various authors organized under the following topics: environment of family planning programs, program management and program elements, special modes of delivery, client-provider transactions, and methodological issues. The emphasis is on the contribution of various program elements to the effectiveness of organized family planning programs. The consensus is that, firstly, family planning programs have an effect on contraceptive use and fertility independent of the effect of socioeconomic development; and, secondly, that there is empirical evidence on how to make such programs more effective.

This is a two-part examination of the origins of decreased marital fertility in Western Europe. In the general study, the author discusses the history of birth limitation, theories concerning reproductive behavior, and contraception. In the empirical section, the author applies the theoretical and methodological formulations developed in the first section to a case study of Zurich, Switzerland. General historical development, the history of fertility in Zurich, the Protestant ethic, differential fertility according to status and position, and other cultural, social, and demographic variables bearing on the control of fertility are studied. The author then presents a model of the determinants of decreased fertility for Zurich up to the beginning of the nineteenth century.

Contraceptive methods used after discontinuation of oral contraceptives are examined using data on 7,969 U.S. women aged 15-44 who were interviewed in 1982 in Cycle III of the National Survey of Family Growth. "The decline in current use of the pill during the 1970s coincided with a marked increase in contraceptive sterilization, but was not the result of a direct switching from the pill to sterilization by individual women. Only 21 percent of women who quit the pill chose sterilization as their next method. The majority--60 percent--switched to nonpermanent methods, the condom being the most popular in all age-groups; the proportions selecting the condom as their next method ranged from 20 percent of 15-19-year-olds to 12 percent of 30-44-year-olds. Nineteen percent of former pill users did not adopt any method after discontinuing the pill."

"This research examines changes in contraceptive practice of a cohort of 736 childbearing couples in Bohol, a province in the Philippines, who were interviewed in two surveys. During the interval, roughly 50% of the couples were exposed to a family planning intervention program...." Multivariate logistic regressions are used to examine the hypothesis that motivation and costs are directly related to fertility regulation and that demographic, socioeconomic, and cultural factors are indirectly linked to contraceptive practice through these two variables.

The authors examine the extent of the knowledge of nurses working in family planning and maternity care in Egypt concerning tubal sterilization and vasectomy. The data concern 200 nurses working in clinics, health centers, and hospitals in Alexandria. The results indicate that although nurses know about such procedures, they are generally poorly informed about the preoperative and postoperative care needed for both female and male sterilization, and about the possible complications and side effects. The need for in-service training is stressed.

"Previous research has failed to generate consensus about why black fertility has persistently exceeded that of whites in the United States. In an effort to shed light on this question, this article examines black/white differences in sociodemographic factors affecting contraceptive choice. Using data from the 1976 and 1982 National Surveys of Family Growth, we find a complex pattern of black/white differences. Not only does contraceptive choice vary by race, but the effects of such variables as age, marital status, and education also differ between blacks and whites. For example, compared with whites, black married women avoid coital methods, and compared with blacks, white women shift contraceptive behavior more as they change marital status. The complex nature of the racial differences in contraceptive choice [is] interpreted as reflecting differences in marriage patterns and trends."

"This paper compares two economic strata of vasectomy acceptors--high-income earners and low-income earners--with respect to compensatory payments and the decision to accept vasectomy in urban Sri Lanka. Post-operative problems and acceptors' attitudes toward vasectomy in the two strata are also examined. The results show that as higher levels of payment were offered to potential acceptors, an increasingly larger proportion of lower-income men accepted vasectomy." Comparisons are made concerning number of children and age at vasectomy. The results suggest no consistent negative consequences related to the amount of payment in the two strata of acceptors.

Rural-urban differentials in contraceptive use in Bangladesh are analyzed using data from the 1981 Contraceptive Prevalence Survey (CPS). "The data show that contraceptive use was substantially higher in the urban areas compared to that of the rural areas. The observed urban-rural difference could in part be due to difference in educational attainment of the women in the two areas. According to the CPS data, urban residents are generally...[better] educated and more likely to be favoured by the characteristics that are found to make [a] difference in current use level."

"Survey information on fertility intentions, patterns of contraceptive use, contraceptive failures and abortions is used to develop estimates of unwanted births and of unplanned pregnancies for seven countries, by method of contraception. Potential improvements in contraception, leading to more use of highly efficient methods are considered, and several scenarios for improved contraceptive use are presented. The impact each would have on fertility levels and on abortion rates is estimated. Although improvements in contraception will have only a limited impact on fertility--which is already very low--their impact on abortion could be considerable." The data concern six European countries (Finland, France, Netherlands, Norway, Sweden, and the United Kingdom) and the United States.

"This paper considers the impact of recent efforts to integrate the national family planning programme in Haiti into the Ministry of Public Health and Population as part of a broad-scale effort to improve rural health delivery. In spite of major investment over the last 5 years, there has been a decline in family planning activities, extremely low contraceptive prevalence and a lack of direction in the programme. The family planning management information system did not allow programme leaders and policy-makers to monitor programme results and take corrective action. Too rapid integration, based on little more than conventional wisdom, led to the disintegration of a family planning programme that had shown slow but steady growth and progress for 10 years. Steps needed to improve the situation are discussed."

"In this article we consider whether publicly funded family planning programs in the United States have been effective in reducing fertility rates. Our study seeks to determine through multivariate analysis whether higher program enrollment rates in local areas are associated with lower fertility rates in 1980, when other factors are controlled for statistically." Vital statistics and 1980 U.S. census data are used. It is concluded that "the family planning program has had an impact on aggregate fertility levels, as intended....[and that] this impact has been translated into measurably lower fertility rates among women, including poor women and teenagers, across the entire country. We found higher enrollment rates associated with lower fertility in every model in which prior fertility was controlled for....Finally, we found that the strongest predictor of program enrollment in 1978 was the level of program activity, as measured by the number of program sites."

The communications strategies were implemented for a one-year period in three different semi-rural towns in the southern coastal region of Guatemala, while a fourth community served as a control. There was little change in knowledge or attitudes that could be attributed solely to the program (because changes in the treatment areas were also observed in the control, possibly because of spill-over). However, the number of operations performed in all three treatment areas increased significantly. The strategy employing the male promoter alone generated the greatest number of operations and at the lowest cost."

54:10363 Brown, George F.; Jain, Anrudh K.; Gill, John. Analysis of population policies and programs in India. Sep 1987. vii, 125 pp. Population Council: New York, New York. In Eng.
This is a review of population activities in India, undertaken by the Population Council at the invitation of USAID/New Delhi and with the concurrence of the Government of India. It is the result of a visit by the consultative team to India in 1987 and updates the findings of a similar review conducted in 1982. The report concludes that "the program has made substantial progress since 1982, both in terms of the expansion of service delivery points as well as contraceptive use. The effective contraceptive prevalence rate, after remaining almost stagnant for about five years between 1977 and 1982, has increased from 23.7 in 1982 to 34.9 in 1987. This growth is accompanied by a shift in the balance of methods. The share of sterilization has decreased from about 84 percent in 1983 to 74 percent in 1986." The reasons why such changes have not resulted in a decline in the birth rate are considered.

An analysis of a governmental contraceptive sterilization project carried out in Meerut, Uttar Pradesh, India, in 1985-1986 is presented. The authors review the procedures adopted by the central government for fixing project targets as well as the state government's response. The importance of involving local leadership in program implementation is stressed. The limitations of the inclusion of incentives for sterilization acceptors are also noted.

The author describes recent efforts, begun in 1980, to revive and reorganize the family planning program in Pakistan. The author concludes that the new plan is "a modest, workable scheme for renewing the struggle against rapid population growth in Pakistan. It is not a crash plan which promises dramatic declines in fertility or overnight improvements in the standard of living. It aims at building a solid infrastructural base in the Family Welfare Centres, at creating a trained, motivated staff for these Centres and at working patiently to establish rapport with and support in the local community served. This programme is 'integrated' in the sense that the Centre will provide modest medical services and supplies (MCH and other) but the Centres remain under the Population Welfare Division's control and seem to have little or no contact with the Ministry of Health's programmes."

"This article examines the opinions of Nigerian men toward a wide range of fertility related issues that may affect the success of family planning programs. Specifically, the masculine side of planned parenthood (family planning) was explored in terms of attitudes toward (1) Nigeria's population dynamics, (2) population control policies, (3) sex preference and value of children, (4) ideal number of children, and (5) family planning." The data concern 202 Nigerian men attending U.S. universities in 1984. The results indicate that this sample does not think Nigeria has a population problem, disapproves of government interference in a couple's decision concerning the number of children desired, and believes a woman should have her husband's permission before practicing family planning. The implications of these findings for family planning programs are assessed.

"The following account analyzes the relationship between the population practices in one indigenous community in Mexico and the Mexican government's recent effort to reduce population growth. It shows that the government's fertility-reducing policy was superimposed on a longstanding local conflict between this community's women, who wished to limit the size of their own families, and the community as a whole, which wanted all of its female members to reproduce abundantly." The data concern a sample of 180 women and 126 men from San Francisco, a township in Oaxaca state, and were collected in 1980-1981. The results show that women generally refused the contraceptive services available and continued to have high fertility. The reasons why women did not try to achieve the low levels of fertility desired are explored, with a focus on the cultural barriers to the acceptance of fertility control.

Based on a 5-per-1,000 random sampling survey of women of childbearing age in the Dabie Mountain areas, the authors analyze family planning knowledge, attitudes, and practice in a Chinese rural area. The analysis shows that most rural women are aware of birth control methods as a result of the implementation of China's family planning policy. Of the women surveyed, 99 percent advocated family planning. In spite of the one-child policy, 70 percent of the women in the survey wish that they could have two children. With regard to family planning practice, 50 percent of the women prefer sterilization. Condoms and IUDs are also commonly used. The author elaborates some recommendations for improving family planning in rural China.

The religious-minority-group status hypothesis concerning fertility is tested using data collected by questionnaire in 1985 concerning unmarried college students in central and southern Philippines. The focus is on differences between Protestants and Catholics in attitude toward fertility and family size. The results suggest that Protestants desire lower fertility than do Catholics, and that "support for the religious-minority-group status hypothesis is not limited to minorities with explicitly pronatalist creeds or to religious groups in more developed nations or nations with an indigenous European culture."

"Research has shown that teenagers' perceptions of the advantages and disadvantages of pregnancy and contraception are significant predictors of pregnancy risk taking. This analysis examines the content and determinants of these cost-benefit sets, using data from 425 sexually active adolescents [from New York City]. The results indicate that teens' perceptions of the advantages and disadvantages of pregnancy and contraception are neither strongly nor systematically related to each other. Moreover, the determinants of the four cost-benefit sets are varied, although there is some overlap between sets. Explanations of these findings and implications for future research and for the delivery of family planning services to teenagers are suggested."

The impact of female employment on the approval and practice of family planning in Egypt is examined using data for 400 employees of a television factory and 198 housewives. "The results showed that the percentage of workers who know about the sound meanings of family planning, the different methods of contraception and the presence of hazards and contraindications to the usage of contraceptives were higher than among housewives." Employed women also favored higher ages at marriage, longer birth intervals, and a smaller family size; their use of contraception was also greater than that of housewives.

"This paper first reviews and integrates existing ideas about gender differences in family size desires and son preferences in Third World countries....Most hypotheses agree that economic development, the Westernization of family structure, the decline of fertility, and a reduction of gender inequality should lessen gender differences in reproductive goals, but several disagree about the likely nature of existence of such differences under conditions of poverty, lineage-oriented kin groups, high fertility, and male dominance. A review of statistics from more than three dozen published studies suggests that the claim that women in pretransition settings invariably oppose high fertility more than do men is incorrect, although in the poorer, higher fertility populations men do indeed favor high fertility more often than women do. In most instances, gender differences in son preferences appear to be unable to explain gender differences in the desire for additional children."

"This report summarizes results from analyses comparing voluntarily childless wives to other childless wives and mothers on socioeconomic-achievement patterns, lifestyles and attitudes." Four groups of wives are compared: "childless wives who intend to remain childfree;...childless wives who have not yet decided whether they want to have children;...childless wives who intend to have children in the future; and...wives who have children." Six major topics are considered: "(1) norms and costs relating to children and parenthood; (2) market division of labor or attainment patterns; (3) the couple's economic situation; (4) the household division of labor; (5) patterns of spouse involvement and leisure activities; (6) marital satisfaction." Data are from a stratified random sample of applicants for the years 1969-1974 obtained from records of a marriage bureau agency in a large city in the midwestern United States and concern white wives currently living with their first spouse and married after age 21.

With data from the 1980 Census of Taiwan and the 1980 Demographic Yearbook of Taiwan [the] hypotheses are subjected to empirical test. The final section discusses the implications of [the] investigation." The report calls special attention to women's age differentials and voluntary childlessness since modernization. In general, support is found for the hypotheses that levels of modernization are associated positively with childlessness.

"This study focuses on the content and process of baira ni vato, 'women's talk', communication which occurs in indigenous, informal groupings of women in rural villages in Gujarat, India. The thesis examines how nonliterate women explore their reproductive concerns, and how they engage in the process of assimilating new information regarding fertility options in the context of their culture. Using participant-observation methods 32 groups were documented during three site visits. Of this data set eight groups, the two longest from each of the four castes, were selected for detailed analysis....[The] findings suggest that family planning programs can better address women's needs in these communities by using approaches that draw upon the principles of women's talk, such as the use of the small group, and the values of synergy, self-help, and community participation."

Risks that do not exist are feared and risks that genuinely do exist are incorrectly understood.

In this paper, the hypothesis that fertility decline in the Asian and Pacific region can be explained by economic theories alone is rejected. It is contended that the decline is a result of various socioeconomic determinants at the national, community, and individual levels. Based on data from fertility preference surveys, the report concludes that both attitudes toward contraception and the development of effective family planning programs significantly affect the fertility transition.

"Since 1979 the Chinese government has attempted to carry out a policy of restricting couples to only one child. Although considerable numbers of Chinese continue to give birth to second and higher parity children, this campaign has helped to maintain China's fertility at levels that are unusually low for a Third World country. This article considers evidence from local surveys on preferred family size desires to see how the latter relate to the goals of the campaign. Preferred family sizes reported in these surveys are quite low, but still most respondents want to have two children, with sexes balanced. Furthermore, the effort to foster heightened aspirations for economic mobility as one way of making the one-child goal more acceptable has given rise to desires that may be difficult to satisfy."

This study is concerned with both husband's and wife's choices of labor market activity and their effect on the demand for children. Among the employment factors considered are employment that is compatible with child care as well as family-owned businesses, which may increase the demand for children because of child labor implications. "Micro data from the urban sector of Hong Kong are used to test for the presence of both the compatibility and child labor effects on fertility demand with positive results. Our study shows that incorporating husband's choice of market activity type can be important in the analysis of fertility demand in developing countries."

Data are from surveys involving over 500 U.S. college and high school students undertaken between 1969 and 1972 and followed-up in 1979 and 1981. "Bivariate analyses show that young adult women who have had an abortion are characterized by greater psychosocial unconventionality than women who have not had an abortion. Similar differences along an underlying dimension of conventionality-unconventionality distinguish, antecedent to the abortion experience, women who would later have an abortion from those who would not."

A review of legal abortion in Norway from 1976 to 1985 is presented. It is noted that the number of abortions has varied between 13,500 and 15,200 per year. The author observes that about half the women concerned are unmarried and under age 25. The facilities for counseling and for providing alternatives to abortion seem to be underutilized. The author concludes that the demand for abortion should be seen primarily as an adjunct to changes in fertility norms.

Although these two major sources provide conflicting evidence on current trends, "they both show that the rapid increase in abortions experienced during the 1970s has leveled off, and that the ratios of abortions to births and to pregnancies have declined."

This monograph, which consists of five papers by various authors, is the product of a committee sponsored by the American Psychological Association. It is concerned with the psychological issues relevant to the development of law and policy in the United States concerning adolescent abortion and the provision of guidelines to psychologists involved in counseling minors or conducting research. A chapter is included on the epidemiology of adolescent abortion in the United States in the period 1973-1981.

The role of induced abortion in controlling global population growth is examined. The authors compare population growth rates and abortion (both legal and illegal) incidence rates for 116 of the world's largest countries. They conclude that no country wishing to reduce its rate of population growth to under one percent can expect to do so without the widespread use of abortion as well as high rates of contraceptive prevalence.

"Abortion is a public health issue characterized by a history of controversy. Although abortion studies have been conducted for many years, lack of data has prevented multivariate analyses of covariates of abortion, and it has not been possible to address important questions concerning the net relationships between pregnancy outcome and sociodemographic factors. Using data compiled by the National Center for Health Statistics and log-linear methods, relationships between abortion and selected demographic factors are investigated for 673,868 pregnancies occurring in the U.S. in 1980. Relative risks of pregnant women choosing to induce termination rather than continue the pregnancy to term are estimated."

"This article addresses the issue of the incidence of abortion during recent years in China. It poses and answers three interrelated questions: (1) What has been the role of abortion in the country's population planning successes since the early 1970s? (2) What are the patterns of variations in abortion incidence at the provincial level and by place of residence? and, (3) What are the implications of their numbers and variations?"

The experience of 25 years of legal abortion in the Socialist countries of Eastern Europe, including Yugoslavia, is reviewed. "A discussion is carried out on the [increase in] the absolute number of abortions; the frequency and percentage of abortions out of all registered pregnancies; the influence of the legal regime on these indices; the relation of the number of abortions to the birth rate and fertility; their interrelation with the distribution of contraception, etc." Specific attention is given to problems in Bulgaria resulting from measures designed to reduce the abortion rate.

F.5. Factors Other Than Contraception Affecting Fertility

54:10401 Frisch, Rose E. Fatness and fertility. Scientific American, Vol. 258, No. 3, Mar 1988. 88-95 pp. New York, New York. In Eng.
The relationship between fatness and fecundity in women is explored. The author presents evidence that a woman must store a threshold or minimum amount of body fat in order to be able to reproduce. The possible mechanisms by which the amount of body fat might affect fecundity are examined. Consideration is also given to the effects of dieting and exercise on fecundity.

"The effects of pregnancy termination on subsequent fertility were studied in a group of 845 patients within a WHO organized multicentre trial [in Hungary and the Republic of Korea]. After comparing the index (abortion) and control groups by using the cumulative pregnancy rates per 100 women it was found at 30 months after recruitment to be 96.9 and 98.7, respectively. The difference was not significant statistically."

"From 1975 to 1980 a prospective study of nearly 2,500 married, fertile women was conducted in Matlab, Bangladesh at the International Centre for Diarrhoeal Disease Research. Women were interviewed at monthly intervals to collect information on nutritional and reproductive status, in order to study the factors associated with natural fertility. The median duration of amenorrhoea for women with no child deaths was 15.5 months, with older women and those of higher parities recording longer durations than younger women or those of lower parities. Median duration of amenorrhoea for women with six or more years of education was 8.4 months compared to 16.4 months among women with no education. When classified by weight at preganacy termination, average duration of amenorrhoea of women weighing less than 38 kg was 17.6 months compared to 13.6 months among women weighing more than 44 kg. Proportional hazards analyses show that mother's education, parity, month of birth, supplementation practices and nutritional status were significantly associated with the probability of resuming menstruation."

"Data taken from the 'Determinants of Natural Fertility' study, Bangladesh, are used with multivariate hazard models to study variations in fecundability between women, especially the relationship between nutritional status, breastfeeding practices, and the monthly probability of conceiving. It is found that fecundability varies both between women of a given age and, for a particular woman, by age. The variation is related to four variables: separation, which affects coital frequency; age, which represents biological changes; lactation practices; and the duration of amenorrhoea. Nutrition above famine or starvation levels is not a significant determinant of fecundability. The most surprising finding is the effect of the pattern of breastfeeding on fecundability: as a menstruating woman begins to wean her child, her probability of conceiving increases as her serum prolactin, which inhibits ovulation, decreases. Thus, those menstruating women who are most likely to conceive are those who have completely weaned their infants in the very recent past."

"The paper examines the pattern of breast-feeding among women still in their prime childbearing ages (15-35 years) in Ilorin, the captial city of Kwara state in Nigeria. While breast-feeding is still a common practice among urban women, there is a wide variation in the duration of breast-feeding, depending on the socioeconomic characteristics of the mothers." Educational status and contraceptive practice are shown to have negative effects on duration of breast-feeding. Christians continue breast-feeding for shorter periods than Muslims. The dangers inherent in the early introduction of supplementary feeding are discussed.

"This paper provides evidence that contacts with different elements of the health care system have sharply divergent effects on both the initiation and continuation of breastfeeding. In this paper, analysis of data from a 1981 survey reveals that breastfeeding in rural Mexico is negatively associated with the use of modern maternal care in the respondents' community....The effect of the use of public maternal health care on duration appears to work through its positive influence on the adoption of a modern contraceptive method. The results of this multivariate analysis are supported by those of a survey of health care providers. In comparison with traditional birth attendants, physicians and nurses are less supportive of prolonged breastfeeding, and are less likely to recognize its contraceptive effect. They also favor suspension when the mother takes oral contraceptives or, surprisingly, when the child develops diarrhea."

"This paper examines the determinants of initiation of coitus in early adolescence [in the United States]. Using a panel design on the population of whole schools, we tested determinants in three domains: motivation, social controls, and attractiveness....We interpret the results within the framework of other findings from a hormone analysis of a partially overlapping sample. White males' initiation of coitus in early adolescence is dominated by motivational hormone effects and social attractiveness, with no observed effects of social controls. White females' initiation of coitus is dominated by the effects of social controls. We observed no effect of attractiveness, no hormone effects, and no effects of sexual motivation. Black females' initiation of coitus is dominated by their level of pubertal development (an attractiveness variable), with no observed effects of social controls."

F.6. Fertility Outside Marriage

54:10408 Coward, John. Conceptions outside marriage: regional differences. Population Trends, No. 49, Autumn 1987. 24-30 pp. London, England. In Eng.
"The extent and nature of regional differences in extra-marital conceptions [in England and Wales] are examined from a cross-sectional perspective for 1983. Regional differences in extra-marital conceptions--whether measured on a proportional basis or as a rate--are quite pronounced and the different patterns by outcome (illegitimate maternity, maternity legitimised through marriage, or abortion) are by no means similar....Factors that may be important are the varying provision of certain services, differences in socio-economic and ethnic composition of the population, and variations in regional attitudes and behaviour."

Recent trends in fertility outside marriage in Belgium are reviewed. The focus is on changes in such fertility and attitudes toward it since 1960-1961, particularly in the Dutch-speaking region. The author concludes that the changes have paralleled those involving the sexual revolution, the emancipation of women, and the development of modern contraception. The growth of deliberate childbearing outside marriage is noted.

Recent trends in fertility outside marriage in France are analyzed, with consideration given to the impact of trends in consensual union. The authors note significant changes between 1972 and 1981, particularly with regard to women living in consensual unions. The importance for demographic analysis of distinguishing between single women living with and without the father of their childeren is stressed.

Trends in fertility outside of marriage in the Latvian Republic of the USSR are analyzed. The data are from a sample survey of 921 single women with children. The results indicate that fertility outside marriage is associated with lower educational status, 80 percent of the pregnancies that occurred in this sample were planned, 4 percent of urban women and 21 percent of rural women leave young children without supervision during the time they are at work, fathers provide minimal assistance, and single mothers face great economic and psychological problems in raising children.
