American Community Survey
According to GeoLytics.com, the American Community Survey (ACS) "was designed to measure the changing social and economic characteristics of the US population but not to provide official counts. Among other things the ACS is collected over multiple years and then merged into a common file" (U.S. Census Bureau).
