If U.S. birthrates remain below the replacement level and are relatively constant, and if immigration is constant both in total numbers and age-sex composition, population size will eventually become stationary, according to this policy discussion paper. Moverover, varying the constant annual number of immigrants produces an equal proportionate…

The Commission on Population Growth and the American Future concluded that zero population growth (ZPG) is in the best interest of the United States. To achieve ZPG in the future, the United States must keep fertility and net immigration relatively low. Practical problems are discussed. (RM)

California's recent investment in teen pregnancy prevention has contributed to the largest decline in teen birth rates and the second largest percentage reduction of all 50 states. California's annual teen birth rate is now similar to the national rate. This occurred while the highest teen birth rate group, Latinas, increased as a proportion of…

This paper examines teen births during the period from 1991 to 1996, a period chosen because teen births started to decline in 1991 and 1996 was the most recent data year available. In most cities, the number of births to teens decreased in this period, but in a small number of cities, the number of births to teenagers increased. It is not clear…

The major trend towards worldwide easing of the birthrate does not include the current population patterns in Africa. The population policies of African nations range along a continuum from totally pronatal to strongly antinatal. However, even antinatal policies have had little effect on the overall spiralling upward population trend. (JA)

This model emphasizes the distinction between male and female earnings and the distinction between families with employed wives and those without as they affect the fertility rate. (Author/IRT)

A sample of married and cohabitating women is used to examine the impact of cohabitation on fertility. The transition from cohabitation to marriage does not appear to be influenced by childbearing desires. Once nonpregnant cohabitators marry, the timing of marital first birth is similar to that of women who never cohabitated. (JPS)

A study of 422 female teachers showed that approximately 67% of those who leave teaching leave the work force altogether. A newborn child is the most important determinants of labor force exit. Comparing teacher and nonteacher attrition rates for persons with similar educational attainment, nonteachers are more likely to change jobs/occupations.…

Counting can be done using a linear, exponential method or by using a technique incorporating a recursive process which gives a visual analysis of population data. Population estimates are based on assumptions about change brought about by immigration, emigration, deaths and births.

Recent theoretical work suggests that the increase in women's sense of entitlement to leisure has become a key to understanding delay in childbearing in industrialized countries. Using data from the Japanese Panel Study of Consumer Life, the author examines the relationship between leisure time and childbearing among Japanese married women in a…

In Germany, processes can be observed that have long been out of keeping with the principle of equality of opportunity. Unemployment is concentrated in the structurally weak peripheral areas, in Eastern Germany in particular; emigration of young and better-educated people to the West is not diminishing, but contrary to expectation is again on the…

This paper presents results of a survey of the marriage and fertility histories of women in the United States conducted in June 1990 by the Bureau of the Census as a supplement to the Current Population Survey. The marriage and fertility history surveys were taken in 1971, 1975, 1980, 1985, and 1990. This paper focuses on recent trends in…

Discusses the importance of population control in the modern world and the reasons for and effects of overpopulation. (BD)

This report presents estimates of the population for 1980 to 1986 for Puerto Rico, the American Virgin Islands, American Samoa, Guam, and the Northern Mariana Islands. Census counts for 1980 are also shown for each of the areas. Except for Puerto Rico, all of the areas are growing at a rate well above that of the United States (6.4 percent). Of…
