Population forecasts for France are reassessed in the light of data from the 1990 census. The author notes that although the total fertility rate is close to the anticipated 1.8, mortality is lower than expected. In consequence, the increase in the number of the elderly will be faster and larger than was originally projected.

In this study, the rate of growth of state and local populations in the United States is related to the growth rate of national employment, and to demographic and economic features of the regions concerned, in order to make more realistic long-term population projections. Both natural increase and migration are taken into account in the model developed. "The model is estimated for two regions, the El Paso, TX, standard metropolitan statistical area (SMSA) and the State of New Mexico. Several statistical problems arise because of the limited number of available time-series observations. Fully dynamic historical simulations track the population quite closely, in one case never differing from the actual value by more than 1.17% and in the other never differing by more than 1.36%."

The author presents a comparative analysis of the use of multistate models developed by Andrei Rogers with two types of migration data. A Rogers-type model is used to forecast population changes by urban and rural region, sex, and age for the period 1978-1983 using official Polish data. The results show the importance of selecting the data to be used in making population forecasts, and demonstrate the usefulness of a model of this type for making population forecasts.

The most typical features of the coming population decrease are examined. These include the changing of the age distribution towards a growing proportion of older adults in working life and of the aged, resulting in 25 percent of the population being older than 65 in 2030....[Changes in] the sex ratio...and the proportion of widows and widowers...are dealt with. Finally, the impact of the projected changes on the labor force is focused on, and the means for compensating for the diminishing supply of labor force are discussed."

In Ger. with sum. in Eng.
"This research note develops a multi-state population projection model in which inter-marriage between the states and the following uncertainty about the state of the children plays a major role. Since only 5% of the Austrian population belong to the Evangelical Church, but more than 80% of their members marry partners not belonging to the church, the question of the percentage of children from mixed marriages that become church members turns out to be vital for the future size and age composition of the church." Five different scenarios to the year 2030 are examined.

The author describes population decline in Bologna, Italy. "Since the first half of the seventies the population of Bologna has undergone a continuous decrease caused by the natural and migratory balance deficit. This has deeply changed the age composition of the population: a drastic decrease in the number of [those aged less than] fourteen years and an increase in the number of [those] older. Assuming that, in the [next] ten years, [fertility] and mortality keep constant and the migratory balance becomes negative, a further reduction of the resident population of Bologna may be foreseen together with [more changes] in the demographic pattern." The consequences will include a large increase in the demand for health services, as well as increased employment opportunities.

"This report examines changes in selected parameters of the population of the RSA [Republic of South Africa] and TBVC countries [Transkei, Bophuthatswana, Venda, and Ciskei] over a thirty-year period from 1970 to 2000. Historical demographic data from three population censuses are used in the comparisons of the first fifteen years (1970 to 1985) and combined with...[projections] of demographic movements of the total South African population...to arrive at forecasts for the next fifteen years (1986 to 2000)." Data are included on age and sex distribution and projection, educational levels, and marital status by ethnic groups. The author concludes "that the white population is aging and is increasing at a very slow rate. The coloured and Asian populations are also declining but at a slower rate than the whites. Projections of the black population do not suggest any real deceleration in the present rapid rate of growth. Coupled with soaring black education levels, this will have a profound effect on the future development of the RSA, especially in the spheres of job creation, employment and politics."

The author traces the population decline in the counties of Cornwall and Devon, England, from 1841 to 1961 and the subsequent increases in population up to 1981. She first examines the causes of the decline and then evaluates various hypotheses to explain the turnaround, including retirement migration, improvements in rural infrastructure, and tourism. "It appears, then, that the century-long history of rural depopulation or stagnation has substantially ended, although we shall have to wait for the findings of the 1991 census to clarify this."

"The purpose of this study is to compare the demographic transition in Finland and Hungary during the period 1881-1986. The article deals with the transition of mortality and fertility, changes in reproduction, population growth and age structure. The analysis centers on the classical two-factor model: the development of fertility and mortality, changes in the size and in the age structure of the population by calendar periods and by birth cohorts. The basis of the study [is] population figures by sex and by five-year age groups....As a supplement to the study...six population scenarios have been prepared by the cohort component method, by five-year age groups and by five-year steps from 1991 to 2041."

"For decades Algeria has had one of the highest population growth rates in the world, arising directly from a steady gap between deathrates and birthrates. The reasons are of a complex social, economic and cultural kind, such as high infant mortality, traditionally early marriage, family models largely determined by religion, the common practice of child labour and other factors. As a consequence of the mismatch between economic and demographic growth the society is confronted by growing mass unemployment, underemployment, food supply problems, housing shortages and ecological crises. The critical economic situation in the eighties reduced the prospects for constraining the population explosion by quickly conquering socioeconomic underdevelopment. Nowadays Algeria is deliberately following a programme for family planning, which is also supported to a certain extent by the Islamic clergy."

"The concept of 'demographic discontinuity' and a technique concerning how to measure it were first introduced by Keyfitz (1987...). In the present paper we developed his method for somewhat more detailed measuring of the bend in the curve of age distribution and tested our techniques by applying them to the population data for the world total and several Asian countries....We used the world population estimates and projections as assessed in 1984 by the United Nations...[for China, Indonesia, Japan, the Philippines, and Thailand] as our base material. Using the age-time distribution of the world total population from 1950 to 1980, we calculated not only the first but also the second differences. Both were calculated with respect to time as well as with respect to age....[The focus was] on the bend occurring in cohort-to-cohort growth of population."

"This article describes population development in Finland in the 1980s....The emphasis in this article is on the development of fertility, mortality and migration....[The author finds that] the 1980s signified a period of stable development. The downward trend in fertility and mortality ceased and migration stabilized. The continuing low level of fertility and mortality was reflected in the aging of the population structure. The aging of Finland's markedly large working-age population will strongly increase the proportion of the elderly in the future."

The case is made for controlling Algeria's rapid rate of population growth. The author notes that at the present rate of growth the population is doubling every 20 years. The decline in the labor market and increases in unemployment and underemployment are also examined. The need for strong population policies and programs is stressed.

"This is the first in a series of profiles on results of the 1990 Census of Population and Housing." This profile focuses on population growth in the United States from 1980 to 1990 and changes in state congressional apportionment due to gains or losses in population size. Current population distribution by geographical region and changes in population size and rank for each state are presented for 1900, 1950, 1980, and 1990.
