U.S. Census of Population and Housing Basics : Home

Introduction to finding demographic and housing facts and statistics collected by the U.S. Census Bureau.

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:

  • Household makeup
  • Income
  • Race and ancestry
  • Educational attainment
  • Home ownership
  • Work status

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 was 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 Projections Program publishes estimates of the population for future dates. They are typically based on an estimated population consistent with the most recent decennial census and are produced using the cohort-component method.

The Census Bureau conducts over 130 surveys, on its own and in conjunction with other government agencies. For lists of these surveys, see
