Population Counts

The population is "counted" every 10 years via the decennial census.

Between decennial censuses, see:

Population Estimates

Other reports and surveys

Current Population Reports (CPS).

Much of the current population data is derived from the Current Population Survey (CPS), which is a sample household survey of the noninstitutional civilian population in the United States. Its primary task is to produce monthly statistics on unemployment and the labor force, which are published by the U.S. Bureau of Labor Statistics in its monthly bulletin Employment and Earnings. Much of the data collected is also available at the CPS Internet Site.

IPUMS is composed entirely of sample data, and some subpopulations may be too small to study with the sample data.
Because the data are public-use, measures have been taken to assure confidentiality. Names and other identifying information are suppressed. Most importantly for many researchers, geographic information is limited.

The catalogs and indexes below can also sometimes be helpful:

Subject Index to Current Population Reports can also be helpful. Check the library catalog by report title/ series number.
