American Community Survey
The American Community Survey (ACS) is an ongoing, nationwide, monthly survey covering approximately three-million households each year and is now the source for all of the socioeconomic data that was formerly obtained from the decennial census. ACS data is available for three types of releases depending on population size: annually, three-year periods and five-year periods.
Annual ACS data are available for all geographies (e.g., U.S., states, counties, municipalities, places) with a population of 65,000 or more.
Three-year period ACS estimates are available for all geographies with a population of 20,000 or more.
Five-year period ACS estimates are available for all geographies down to census tracts and block groups.
