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…

In 2002, more American counties (985) experienced natural decrease than at any time in the nation's history. The incidence of natural decrease has diminished since then, but remains near record levels. It is most common in rural areas remote from metropolitan centers. Spatial concentrations exist in the Great Plains, Corn Belt, and East Texas,…

How can teachers encourage their geography students to make sense of big numbers? The key math skills geography students need to apply are ones they learned long ago in fifth grade: estimation and place value. However, in order to recognize the size of a city, or strength of a country's per capita income, or value of a birth rate, they need…

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…

Used data from 1940 through 1980 Public Use Samples of the United States Census to examine how changes in fertility patterns of women have affected age distribution of parents for successive cohorts of children. Found decline in average age of mothers and fathers across cohorts of children, partly reflecting a rapid increase in teenage pregnancies…

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…

Recent trends and differentials among the Soviet Union's 15 republics and major nationalities are reviewed, focusing on fertility, mortality and urbanization, the prospect for labor supplies and military manpower, emigration, and projected population growth to 2000. Estimated at 270 million as of mid-1982, the Soviet population is currently…

This article suggests that there are three principal sources of metropolitan population decline: the declining birth rate, the reversal of rural-to-urban migration, and inter-metropolitan migration. (Author/AM)

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,…

This paper considers U.S. immigration in terms of this country's fertility, mortality, and migration rates and patterns. Statistics and estimates are provided for both legal and illegal immigrants, and the positive and negative effects of population growth and decline are explored. The paper concludes that rising immigration rates will help…

Future trends in population are described as they relate to developed and developing nations. It is suggested that for the next 20 years there will be a decrease in population growth rates for all areas of the world except Africa. (Author/SA)

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.…
