ABSTRACT
This working paper discusses the methodology and assumptions used to develop the recently released
projections of the population of the United States from 1999 to 2100. The new series includes projections
of the population by single year of age, sex, race, Hispanic origin, and nativity. While the basic
methodology used to produce these projections is the same as in earlier Census Bureau national population
projections, there have been changes, in both the time horizon and reference dates of the projections, as well
as in the specific methods used to estimate population change. The extension of the series to 2100 carries
the projections 20 years further into the future than any series previously issued by the Census Bureau.
For the first time, projection results include a break on nativity, defined dichotomously by the presence or
absence of U.S. citizenship at birth, as well as its cross-classification with other variables. Also new with
this series is the projection to quarterly reference dates, allowing users to view the national population
seasonally, or simply to select annual reference dates other than July 1. In addition, international migration
in the new series is allowed to vary over time, remaining somewhat lower than the constant value in the
previous series for the first two decades of the century, but reaching considerably higher levels than in the
previous one after 2020. Fertility rates in both models are allowed to change very little over time.
However, fertility rates by race and Hispanic origin are allowed to converge in the new middle series,
whereas in the previous middle series they remained constant within race and origin category. Finally, the
new mortality assumptions show more improvement in life expectancy for all racial and Hispanic origin
groups, except the non-Hispanic White population, than did the assumptions of the previous projection
series.

Health, Nutrition & Population - World Bank

Provides a variety of reports, publications, data and statistics on matters relating to health, nutrition and population in underdeveloped countries. Some topics covered are: health systems development; population/reproductive health; HIV/AIDS; nutrition; poverty and health, and public health. Information can be searched by topic, country, and region.

World Bank Health, Nutrition and Population Statistics Database

One-stop data source for health, nutrition and population indicators from various national and international data sources. Provides direct access to more than 100 indicators, with time series for countries and country groups from 1960 to the most recent year, where data are available.

Selected Historical Decennial Census Population and Housing Counts

Lists major releases of historical census data online for the country, states, cities, metro areas, etc. Very useful starting point for historical census questions.

DHS countries

Choose a country and then select tabs for surveys, quikstats, and publications.

The Demographic and Health Surveys (DHS) project is the third consecutive worldwide research project initiated by the U.S. Agency for International Development (USAID) to provide data and analysis on the population, health, and nutrition of women and children in developing countries. Its two predecessors, the World Fertility Survey (WFS) and the Contraceptive Prevalence Surveys (CPS), paved the way for the DHS project by focusing their research on questions related to fertility, family planning, and mortality. They also helped develop DHS' current reputation as a leader in the field of demographic and health research.

Demographic and Health Surveys (DHS) by country

Demographic and Health Surveys (DHS) are nationally-representative household surveys with large sample sizes (usually between 5,000 and 30,000 households). DHS surveys provide data for a wide range of monitoring and impact evaluation indicators in the areas of population, health, and nutrition.

DOLPHN

The Data Online for Population, Health and Nutrition (DOLPHN) is an online statistical data resource of selected demographic and health indicators gathered from various sources for several countries of the world. The DOLPHN system is designed to provide users with quick and easy access to frequently used statistics.

U.S. Interim Projections by Age, Sex, Race, and Hispanic Origin

Population Estimates - U.S. Census Bureau

The Population Estimates Program publishes total resident population estimates and demographic components of change (births, deaths, and migration) each year. We also publish the estimates by demographic characteristics (age, sex, race, and Hispanic origin) for the nation, states and counties.
