What Does the U.S. Census Bureau Do?
The U.S. Census Bureau collects a variety of data about the U.S. population and economy. Some of the most frequently-used censuses and surveys include:
The Decennial Census is a constitutionally mandated population count undertaken every ten years. Decennial census data includes information about:
Aggregate data is released as available following each census, while individual census records (i.e. personal names and addresses) are kept sealed for 72 years to protect individual privacy. For more information about when different kinds of 2010 Census data will be published, see this page from the Census Bureau.
The American Community Survey collects more detailed information about a sampling of households on an ongoing basis. The ACS replaced the decennial census "long form" in 2001.
The Economic Census profiles U.S. national and local economies every five years.
The Census of Governments profiles the nation's state and local government sector, with information on governmental structures, payrolls, and finance, every five years.
The Population Estimates Program publishes estimated population totals for the previous year for cities and towns, metropolitan areas, counties, and states.
The Census Bureau conducts over 130 surveys, on its own and in conjunction with other government agencies. For lists of these surveys, see
