Between 2014 and 2060, the U.S. population is projected to increase from 319 million to 417 million, reaching 400 million in 2051. The U.S. population is projected to grow more slowly in future decades than in the recent past, as these projections assume that fertility rates will continue to decline and that there will be a modest decline in the…

Fertility rates have fallen dramatically around the world. In some countries, there are no longer enough children being born to replace adult populations. The disappearance of children is a matter of concern matched only by fears that childhood is becoming too structured or not structured enough, too short or too long, or just simply too different…

The study of demography must begin with an understanding of the three sources of population changes: fertility, mortality, and migration. This paper leads prospective demographers--or anyone interested in population--through the dynamics of these three variables, introducing them to the forces that cause populations to grow or decline, and that…

Global Population Profile: 2002 summarizes the most important trends in global population at the dawn of the 21st century. The presentation is organized around four themes: (1) Global Population; (2) Growth, Global Population; (3) Composition, Contraceptive Prevalence in the Developing World; and (4) the AIDS Pandemic in the 21st Century. This…

On January 1, 1987, the total population including Armed Forces overseas approached 243 million, having increased by 2.2 million or 0.9 percent since January 1, 1986 and 15.7 million since the April 1, 1980 census. The number of births per 1,000 population dropped slightly from 15.7 in 1985 to 15.3 in 1986. The 3.7 million births in 1986 were the…

The relationship between changes in the timing and quantity of fertility, such as those that might result from an effective family planning program in developing countries, and changes in child and maternal mortality is examined. Results from five multivariate studies estimate the changes in mortality that might occur from altering maternal age,…

Examines demographic information about the status of young children around the world. Graphs nations with the largest populations of young children and highest percentage of their populations composed of young children in comparison to the aged, the percentage of regional populations under age 5 and over 64, and birth and infant mortality rates.…

Research in population trends is reviewed in this report. The background of population research is examined in reference to methodology and costs. Research conducted by demographers and other population scientists are compared in four areas: fertility, mortality, migration and population redistribution, and population composition and change.…

Population changes which have occurred within the black, Anglo, and Spanish surnamed populations in Texas from 1950 to 1970 were analyzed. This 20-year time span was selected because of the availability of the comparable census information for these groups. Three aspects of population dynamics examined were: growth, components of growth, and…

A systematic discussion of the consequences of rapid population growth for economics and social systems examines growth resulting from mortality decline in the absence of comparable fertility decline. Growth resulting from net migration is also considered. The background and rationale for the study are supplied in a brief introduction. Part 2…

The low fertility of Western industrial nations is likely to become a permanent condition; in the absence of immigration, populations with below-replacement fertility will eventually decline in size. But at the same time fertility is declining, international migration to the West is accelerating. Legal immigration to the United States rose from…

National and regional student population projections and factors related to enrollment trends are provided in this report. Demographic data are presented on national and regional enrollment trends and projections, the national and regional school-age population, regional and state growth patterns, minority populations and immigration patterns, and…

This document reviews China's population trends and policies since the People's Republic was founded in 1949. Areas addressed include: population growth before 1949, population growth from 1949-1982, and policy responses to population growth (including wan xi shao: later marriages, longer intervals between birth, and fewer children); mortality…

Fertility trends estimated alternately from birth histories and own children method are compared for eight developing countries in which the World Fertility Survey was conducted. Principle hypotheses are that fertility trends estimated by the two approaches suffer from similar errors in the reporting of women's and children's ages, and that these…

Population projections developed by the Pennsylvania Department of Education, 1970 to 2000, have been updated to report the latest information on fertility and mortality trends and migration within the State. Methology utilized closely resembles the cohort component procedure, with multiple regression analysis applied to historical information for…
