The U.S. Census Bureau has produced annual American Community Survey (ACS) data since 2005.

The ACS collects sample socio-economic and housing data similar to the “long form” surveys in past decennial censuses. With the ACS, however, the Census Bureau releases current estimates every year, rather than the once every ten year data release that was available with each decennial census. It includes data on more than 40 topics, such as educational attainment, income, occupation, commuting to work, language spoken at home, nativity, ancestry, and selected monthly homeowner costs.

The ACS produces highly detailed social, economic, housing, and demographic statistics in the following series:

• Five-year estimates (all geographic areas, including census tracts)
• One-year supplemental estimates (selected data for areas with a population of 20,000+)
• One-year estimates (areas with a population of 65,000+)
