US Census of Population & Housing Decennial Censuses

The U.S. Bureau of the Census has been collecting data since 1790. When people think of the Census Bureau, they usually think first of population statistics, but the agency also gathers economic and other data. See the tabs above for information on those topics.

Overview of US Census

The type of data collected by the US Census has varied over its history, 1790 to present.  The census' primary purpose is the allocation of representatives to each state for US House of Representatives and not a complete socio-economic survey of the populace.   The type of data available from the census can vary and even the questions asked by the census taker or census questionaire varies with each decennial census.  The 2000  Census was the last decennial census in which detailed data was gathered from a sample of the population using the long-form questionnaire.  Starting in 2001, detailed sample data is being gathered as part of the American Community Survey.
