[El curso final de la transición: la negación posible del futuro de la población mayor y de la población total en México.] Papeles de Población, Vol. 4, No. 17, Jul-Sep 1998. 9-13 pp. Toluca, Mexico. In Spa.
The author briefly considers some future implications of the demographic transition that Mexico has recently experienced. The author makes the following conclusions: that the transition was encouraged by national policies that were primarily economic in orientation; that significant social costs have had to be paid by the people in achieving the transition; that the migration patterns that were part of the transition have adversely affected rural areas; and that the significant aging of the population associated with the transition will cause major problems for society in the coming years.

65:30575 Bourdelais, Patrice. Demographic aging: a notion to revisit. History of the Family, Vol. 4, No. 1, 1999. 31-50 pp. Stamford, Connecticut. In Eng.
"The article analyzes the concept of `demographic aging', why `age 60' (years) was chosen as a threshold for the start of `aging', and how these notions have been applied in France. Since the nineteenth century, tremendous changes have occurred in the meaning of `age 60', both in terms of the social and familial roles a person of that age is expected to play, and in terms of expectations regarding such persons' productivity. The author argues that the notions of `demographic aging' and `age 60' have been conducive to a negative portrayal of old age, have served as a hindrance in the development of social policy towards aged people, have played a role in reducing the number of active people over 55 years, and have reduced medical research on the processes of aging."

Three alternative methods of projecting the number of centenarians who will be living in Belgium in the year 2010 are presented, the first two of which use official statistics and the third a database of Belgian centenarians since 1970 developed by the first author. The value of basing projections of this kind on both sources of data is stressed. The results suggest that the number of centenarians will continue to grow, but at a slower pace than in the period 1947-1994.

"The present article joins two generally separate streams of research, gerontologic and immigration research in the United States. The paper considers data from several studies of seniors in Cleveland, Ohio in the 1990s; the `Black and White Caregivers' and the `Use of Services of Black and White Elderly'. These are considered not in terms of their original research goals, but rather in terms of a reflective examination of assumptions regarding the identity of the elders and caregivers that framed the two studies." The authors conclude that identifying elderly people by race tends to conceal rather than clarify ethnic and cultural differences among this population.

Demographic trends in the Spanish region of Castilla y León are analyzed. The author notes that this region, which covers 19% of the national territory, contains only 7% of the total population. The region is experiencing a significant degree of demographic aging due to many causes, including both out-migration and declining fertility. Details of the aging process in the various districts and subdivisions of the region are also provided. The author sees no alternative to the region's negative demographic situation in the foreseeable future.

An attempt is made to estimate the probability of older people in France who need help on a regular basis having a descendant relative in a position to help them. Comparisons are made between the situation for cohorts born in 1900, 1950, and 2000. Particular attention is given to the impact of the different demographic realities among different social classes in the same cohort. The focus is on the methodological issues involved.

The implications of demographic aging for the future planning of socioeconomic welfare for the elderly in Mexico are considered. The inevitability of the demographic aging process is first established. Next, the relationship between demographic aging and development is considered. Finally, the author spells out the problems of providing for the needs of the elderly, particularly in the area of social security and health.

"Exposure to floods and earthquakes is associated with a lower proportion of male to female children conceived at the time of the disaster. To test the hypothesis that exposure to severe life events before conception might also reduce the sex ratio [the authors] studied all births to Danish women in 1980-92.... They identified 3,072 pregnancies where the mother's partner or children had been admitted to hospital with cancer or myocardial infarction or had died in the year of birth or previous year. The proportion of boys was 49.0% in the exposed group and 51.2% among controls. The nearer the exposure was to conception, the lower the sex ratio."

"After almost 20 years of reform discussions in Germany, a new political regulation came into force on 1 January 1995, in order to substantiate requiring care--elderly primary care (Pflegeversicherung). The demographic development in Germany represents one point of reference for considerations on how to finance and legally regulate such a validation. The number of persons requiring care at all ages in Germany is estimated to have presently reached about 1.65 million. Thus, as far as the general population is concerned, requiring care does not represent a serious risk. However, with growing age the need for care does become a `typical' situation in life: about ten per cent of persons aged over 65 were in need of care in 1993, and one third of those aged over 80."

The objective of this study is to estimate the extent to which the women who were mothers during the baby boom in Canada are likely to be on their own in their old age. The likely presence of both husbands and children is examined. The results show that, in 1991, 33.5% of women aged 65-69 lived alone, and that 6% of women had neither spouse nor child to come to their aid in time of need. The author concludes that women who were mothers in a period of high fertility were no better off than women in other periods.

The extent to which changes in the major demographic variables have caused the aging of the population of Mexico is analyzed. These factors include the decline in mortality since 1950, the increase in international migration since 1950, and the decline in fertility since 1963. These effects are illustrated using a series of age pyramids with and without the impact of the factor under consideration.

The case is made that global aging will become the transcendent political and economic issue of the twenty-first century. The author argues that, as a consequence of this global aging, renegotiating the established social contract will soon dominate the public policy agendas of the world's developed countries. He points out that by the 2030s, over half of the population of today's developed countries and about two-thirds of their voters will be near or beyond today's eligibility age for publicly financed retirement. He therefore asks questions about who will be doing the work, paying the taxes, saving for the future, and raising the next generation. Some alternative ways to resolve these problems are proposed.

"This paper investigates the association between population age structure, particularly the share of the population in the `prime saving years' 45-60, and the returns on stocks and bonds. The paper is motivated by the claim that the aging of the `Baby Boom' cohort in the United States is a key factor in explaining the recent rise in asset values. It also addresses the associated claim that asset prices will decline when this large cohort reaches retirement age and begins to reduce its asset holdings. This paper begins by considering household age-asset accumulation profiles. Data from the Survey of Consumer Finances suggest that while cross-sectional age-wealth profiles peak for households in their early 60s, cohort data on the asset ownership of the same households show a much less pronounced peak.... The paper then considers the historical relationship between demographic structure and real returns on Treasury bills, long-term government bonds, and corporate stock. The results do not suggest any robust relationship between demographic structure and asset returns.... The paper concludes by discussing factors such as international capital flows and forward-looking behavior on the part of market participants that could weaken the relationship between age structure and asset returns in a single nation."

"The age structures of the fifteen former Soviet republics represent very different demographic histories...[and] have different policy implications for the new governments of these countries. The European and Baltic areas must plan for the needs of aged populations, whereas the Central Asian countries must plan for the needs of relatively young populations. Before considering the different population demands that will be placed on these new countries, it is necessary to examine the past trends in fertility and mortality that are responsible for shaping these age and sex structures."

"The common cycle length variation of the woman's cycle in a healthy population is five days.... We believe that the temperature shift in the middle of the cycle is caused by the peripheral effect of estradiol and progesterone on the peripheral circulation. The time from the beginning of the development of an individual spermatozoa to the appearance of a ripe spermatozoon in the ejaculate is about three months. The lifespan of the ripe oocyte is 18-24 hours. The duration of fertilizing capacity of sperm can be five days with decreasing probability; in very rare cases it can be seven days. The probability of conception in our very simple model was 33.3% at ovulation day (day 0)."

"Data from a community-based survey conducted in two rural counties of Anhui Province in China indicate a...downward secular trend in age at menarche for Chinese women.... This rapid decrease in age at menarche may partly be due to better nutrition and living standards reflected by the improved socioeconomic standards experienced in China over the past few decades. To test this hypothesis, a number of determinants of age at menarche were assessed; year of birth, literacy status, county of residence, amount of physical labour, general health status, pesticide exposure before age at menarche, and drinking water source were all found to be associated with age at menarche."

"This chapter describes a series of cross-sectional and longitudinal studies of adolescent sexuality that was initiated by J. R. Udry and colleagues in the late 1970s. These studies were based on an endocrine-behavior theory, and attempted to fill in some of the gaps left by other theoretical approaches to adolescent sexuality." The results "are consistent with an endocrine-behavior model proposing that pubertal increases in T [testosterone] directly contribute to the timing of sexual initiation during adolescence and to the frequency of sexual experiences." The data are from the United States.

An analysis of several cofactor effects upon ALE and DLE is presented using data from [an Iowa epidemiological survey]."

This is a selection of studies by various authors on the problems associated with validating claims of exceptional longevity. "The history of longevity is a history of myths. This volume shows that most reported instances of exceptional longevity are incorrect. This was the rule everywhere until the end of the 19th century and is still the case in the vast majority of countries. It is only when reliable birth registrations are available for a century or more and when reports of ages above 100 are systematically checked against these data that the quality of national statistics on exceptional longevity improves. Several chapters of this volume provide further evidence that genuine centenarians before 1800 were nonexistent or at least extremely rare."

"This study maps the relationship between subjective and actuarial life expectancy in a 1995 national sample of 2,037 Americans of ages 18-95. Subjective estimates parallel age-specific actuarial ones based on current age-specific mortality rates. However males expect to live about 3 years longer than the actuarial estimate and blacks expect to live about 6 years longer. The apparent optimism remains after adjusting for socioeconomic status and the signs and symptoms of good health. Contrary to economists' rational-expectations hypothesis, young adults do not adjust their life expectancies upward to account for the favorable trends in mortality rates."

"The paper presents a study on the length of [the human] menstrual cycle and of its phases [using] a data base provided by the Catholic Marriage Advisory Council of London.... An original aspect of the research is the identification of classes of gynecological age, that is age groups homogeneous as far as the cycle length or the length of its phases is concerned. In spite of the evident dominance of the preovulatory phase length on the total cycle length, the work has evidenced a strong compensatory effect between the pre and postovulatory phases, which leads the total cycle length to concentrate around 27-28 days.... A method to determine a distribution model for cycle length is proposed via kernel density estimation."

"Resource exchanges among multiple family generations are examined using social network measures. A specific focus is on pathways through which older adults transfer resources from one generation to another. The paper uses data that provide...information on transfers in family networks: the 1996 Philippine Survey of the Near Elderly and Elderly and the 1989 Taiwan Survey of Health and Living Status of the Elderly. Measures of the direction and intensity of exchange are examined to identify similarities and differences between the two countries, and likely explanations for these patterns are discussed. Findings show that although the availability of and coresidence with specific types of family generations appear to be quite similar in both countries, there are substantial differences in the amount and nature of family exchanges."

"The current official poverty measure compares income to needs within a family.... I explore issues involved in expanding the unit of analysis, including the stability of cohabiting and other nonfamily household relationships and the degree of resource sharing that takes place among different types of people within households. Instability in households with nonfamily members is not a serious problem for inferring poverty from cross-sectional studies. On the other hand, income from people in nonfamily household roles contributes slightly less to helping other household members avoid financial hardship, implying that nonfamily housemates have a greater tendency to keep income to themselves."

"This paper considers the macroeconomic determinants of migrants' remittances to their countries of origin. In contrast to some previous analyses, we find, using data for Egypt, that both exchange rate and interest rate differentials are important in attracting remittance flows through official channels. We also find that imports financed through remittance earnings have a very high income elasticity which suggests either that these imports are consumer durables and luxury goods or that they are undertaken by higher income groups."

"We examine the mobility of individuals in the United States based on equivalent family income--that is, total income of all family members adjusted for family size according to the equivalence scale implicit in the U.S. poverty line. Our analysis, which tracks movements across quintiles, centers on four questions: How much movement is there across the family income distribution? How has this mobility changed over time? To what extent are the movements attributable to factors related to changes in family composition versus events in the labor markets? In light of major socioeconomic changes occurring in the quarter-century under study, have the determinants of mobility changed over time? Our findings indicate that mobility rates in the 1980s differed little from those in the 1970s."

We show how this manifests itself in a long time series of cross-sectional datasets."

The extent to which the demographic behavior of the poorest sections of a society differs from that of other groups is examined using the example of Cameroon. Data are from the 1991 Demographic and Health Survey. Specifically, the authors attempt to answer the following questions: Is poverty an obstacle or an incentive to changes in demographic behavior? Does poverty give rise to or block declines in mortality and fertility? And does poverty exaggerate the diversity of demographic responses in matters of nuptiality, contraception, and health?

"Using a sample of lone elderly [U.S.] parents and their adult children, we analyze the direct and indirect effects of marital disruption on four important dimensions of intergenerational transfers: coresidence, financial assistance, adult children's provision of informal care, and parental purchase of paid care. Our findings suggest that divorce has deleterious effects on intergenerational transfers, particularly for elderly fathers. Remarriage further reduces exchange. Our results reveal that parents engage in lower levels of transfers with stepchildren relative to biological children. Moreover, intergenerational transfers are sensitive to characteristics of biological children but not to those of stepchildren. Taken together, these results suggest that exchange at the end of the life course continues to be adversely affected by marital disruption."

"How one conceptualises the impacts of migration depends on whether one takes the viewpoint of aggregate area-level income change, of per capita change, or of longer-term (future earnings) change. Several empirical analytical measures are proposed in order to conceptualise the various income impacts of migration.... [A] decomposition procedure is developed for examining how the changes in per capita income of states reflect three different income differentials: those between (a) in-migrants and `stayers', (b) out-migrants and `stayers', and (c) in-migrants and out-migrants. Examination of these measures, and of typologies based on them, highlights how income migration significantly and differentially impacts upon U.S. states. The methods are illustrated here in the context of an important new American data source: the 1993-94 migrant income data released by the U.S. Internal Revenue Service."

Thus, we can determine if, and how much, the sibship-size effect is confounded by other family influences that are difficult or impossible to control in conventional regression analysis.

"In this paper [the authors] update earlier work on racial and ethnic segregation by income to test assertions made by some observers that segregation is now largely a matter of class rather than race [in the United States]. Using the Summary Tape Files of the 1990 Census of Population, [the authors] measure the segregation of Blacks, Hispanics, and Asians within four categories of income: poor, lower middle class, upper middle class, and affluent. For all metropolitan areas containing at least 5,000 members of the group in question, [the authors] compute indices of dissimilarity and interaction between minority members of a certain income and Whites of all income, thus measuring the extent of overall racial/ethnic segregation by social class. We find that Black residential segregation persists at high levels across all income levels, and that the gap between Blacks and other minority groups actually increases as income rises."

"This paper uses data from a nationally representative sample of Botswana women in conjunction with focus group interviews to describe the impact of schoolgirl pregnancy, and to identify the factors that facilitate the return to school of girls who did drop out because of pregnancy. The results indicate that the problem of schoolgirl pregnancy may be much more severe than is commonly assumed. Although the situation is improving, there is a need to continue to improve programmes to reduce adolescent pregnancy, and a need to try and increase the number of young mothers who return to school to complete their education."
This is a revised version of a paper originally presented at the 1997 Annual Meeting of the Population Association of America.

"Using data from nearly 600 adolescents aged 12-19 in combination with data collected from 33 primary schools that the adolescents attended, this paper explores whether certain aspects of the school environment affect the likelihood of early and unprotected sex among adolescent girls and boys in three districts of Kenya. Because of the concern with `schoolgirl pregnancy' in Kenya, the paper also explores the temporal relationship between premarital sex and pregnancy on the one hand, and school dropout on the other."

"The effects of migration on identity and the social position of Chinese women in Belgium were examined from an intergenerational perspective. At the macro level, policies and the general discourse on migration and migrants in Belgium were examined to assess the level of inclusion or exclusion of Chinese women.... The findings will show that although the Chinese are non-existent in official policy and statistics, they are set apart in mainstream society because of their different phenotypical traits. This leads to their exocitization and discrimination in many such social settings as daily life, the workplace and at recreational centers."

In Fre.
An analysis of residential patterns in Dakar, Senegal, is presented using data from a survey carried out in 1989. The results show that next to employment, housing availability is the most important factor governing an individual's ability to initiate a new household in the city. Many individuals never manage to set themselves up independently, and those who succeed do so at later ages because of the unfavorable economic climate. Increasing levels of unemployment and the weakening of traditional extended family ties, combined with the rapid increase in the number of young people suffering the consequences of these trends, give cause for concern.

The author examines the results of including an ethnic question in the 1991 census of Great Britain. "Half a century has now passed since mass migration began, and in most communities at least a quarter of a century since the influx reached its peak. Hence we are now in an excellent position to begin to assess how each of these communities has fared during the intervening years, and thus how far their hopes of upward mobility have in fact materialized. Furthermore, and perhaps most significantly, we can now begin to explore just how varied these trajectories of adaptation have proved to be."

"Even though the inclusion of an ethnic question has undoubtedly added an important new dimension to the [UK] Census, deciding how data associated with the new ethnic group variable can best be interpreted is by no means a straightforward task.... My central objective is to bring the underlying issues into clearer analytical focus. To this end I begin with a brief review of the current state of racial inequality and ethnic diversity in Britain--both to set the issues in a wider context and to highlight the differing significance of the concepts of race and ethnicity--and then move on to consider the way in which the question itself was constructed."

"For the past four years, the [U.S.] Office of Management and Budget (OMB) has been conducting a comprehensive review of the statistical standards that are used throughout the Federal Government to collect and publish data on race and ethnicity.... The review's objective has been to enhance the accuracy of demographic information about our Nation's population, which is becoming increasingly diverse primarily from growth in immigration and from interracial marriages." This paper briefly outlines the recommendations and standards of the review.

This is a general description of the Albanian people living in Yugoslavia and its successor states, and of the efforts that have been made over time to prevent the aspirations of this ethnic group from resulting in a politically united Greater Albania. The main focus is on the history of Serb efforts to influence the ethnic composition of the Serbian province of Kosovo, considered by Serbs to be an integral part of Serbia, although mainly populated in recent years by Albanians.

"The population of Gypsies in Hungary, as arrived at by various estimates made over the past 100 years, has risen at a rate exceeding the increase of the population as a whole.... The rise in number and proportion arises from the high fertility rate--more than twice of the country in total." Aspects examined include age distribution, spatial distribution, employment and occupations, unemployment, income, and socioeconomic status.

"This paper provides estimates of ethnic minority populations in 1981 in Greater London so that spatial population change can be measured. The estimation method involves the application of conditional probabilities of ethnicity given the country of birth. Several different data sources from the census of population have been used to compute the conditional probabilities. Each of these sources has deficiencies; the new method proposed here employs data on 1981-91 survivors in the ONS Longitudinal Study (LS). The estimated ethnic minority populations for 1981 are smaller than those generated using 1991 Census data, and hence the estimate of change is larger. Careful pairwise comparisons are made between alternative estimates. A set of very different maps of change, based on the LS method, are presented and interpreted for the ethnic groups of London at the borough scale."

"Since 1890, every U.S. census but one has asked about the language characteristics of the U.S. population. This almost uninterrupted data series, however, has been shaped by contemporaneous presumptions about the ties between language and ethnicity, the likelihood of proficiency in English among various subgroups, and practical constraints. I describe shifts across censuses in the phrasing of questions about language, the coding of responses, and the subpopulations for which the questions were asked and the results were published. I then describe the data generated by these items and discuss their interpretation."

"Increased public policy focus on indigenous Australians over the past 30 years has resulted in a substantial expansion of demographic analysis over the same period. This paper reviews these efforts and summarizes the main topics, findings and debates. The accumulated evidence points to both demographic change and continuity. Change: in that mortality has declined; fertility levels have been much reduced; urbanization has burgeoned and population growth has entered a phase of rapid increase. Continuity: because mortality is still much higher than the Australian average; fertility remains at a level well above that reported for all women; most individuals still live away from major cities; and the estimation of overall numbers still hinges on a social construction of identity."

In Fre. with sum. in Eng; Spa.
"The aim of this article is to examine to what extent a growing linguistic mobility toward French would be able to curb, or even reverse, the effects of the slow growth rate of Quebec's Francophone population. To answer this question, a large number of hypotheses on the future evolution of linguistic behaviour, all very favourable to the Francophone group, were combined with various demographic contexts. The results of all the scenarios tend toward the same conclusion: the impact of linguistic mobility is marginal, so that a decline in the number and relative importance of the Francophone group seems inevitable."
