The Census Bureau makes population projections at the United States and state levels. For a list of projections contacts in specific states who may make projections for smaller geographic levels, click here. Population projections of a variety of characteristics for the United States and states are available by clicking on Population - Projections under Subjects A-Z. International projections are available in our International Database.
The Census Bureau makes population estimates at the United States, state, county, metropolitan area, minor civil division, and place levels. Current population estimates also are available by age, sex, race, and Hispanic origin for the United States, states, and counties for selected reference years. The Census Bureau does not produce population estimates by age, sex, race, and Hispanic origin below the county level. We also produce housing unit and household estimates. The estimates site is updated regularly and contains the most current estimates available.
The Current Population Survey and the Survey of Income and Program Participation provide detailed social, economic, and demographic characteristics of persons and households for the United States. If you want current detailed characteristics information for the United States, click on the topic (e.g., education, marital status, mobility) you need under Subjects A-Z or use the Data Extraction System (DES) access tool. Some historical data are also available by subject.
Decennial censuses provide detailed characteristics of the population for census tabulation geography. On the Internet, the American FactFinder provides access to these detailed characteristics for a wide variety of geographic levels (e.g., United States, states, counties, places, census tracts, ZIP Codes, Congressional districts). Selected 1990 census data also are available. We have no on-line data access tool for censuses prior to 1990.
The Census Bureau has limited other historical data accessible through the Internet. Check under each topic listed under Subjects A-Z. Pages from historical census volumes can be photocopied and mailed/faxed for a fee.
Federal Depository Libraries may also have historical census volumes.
The genealogy page provides information on research sources available.
