American Community Survey (ACS)

The American Community Survey (ACS) is a replacement for the census long-form. Its design allows for the release of census-type data on an annual basis for all census geographies ranging from block groups to the nation.

The ACS is collected in every month of the year with an annual sample size of about 3 million addresses.

Starting in 2010 the ACS can support the release of data for all geographies. The data are released as 1-year, 3-year, or 5-year estimates depending on the population size of the geograpic unit.

The ACS collects the same data census long-form did, but depending on the needs of Congress additional variables can be added. New iterms since the 2000 census long-form include recent fertility, health insurance, and service-related disability.
