| American Community Survey: 3-Year Estimates: Detailed Tables 3-Year | The American Community Survey (ACS) is a nationwide survey designed to provide communities a fresh look at how they are changing. The ACS replaced the decennial census long form in 2010 and thereafter by collecting long form type information throughout the decade rather than only once every 10 years.
Questionnaires are mailed to a sample of addresses to obtain information about households -- that is, about each person and the housing unit itself.
The American Community Survey produces demographic, social, housing and economic estimates in the form of 1-year, 3-year and 5-year estimates based on population thresholds. The strength of the ACS is in estimating population and housing characteristics. The 3-year data provide key estimates for each of the topic areas covered by the ACS for the nation, all 50 states, the District of Columbia, Puerto Rico, every congressional district, every metropolitan area, and all counties and places with populations of 20,000 or more.
Although the ACS produces population, demographic and housing unit estimates,it is the Census Bureau's Population Estimates Program that produces and disseminates the official estimates of the population for the nation, states, counties, cities and towns, and estimates of housing units for states and counties.
For 2010 and other decennial census years, the Decennial Census provides the official counts of population and housing units. | 2011 | acs› acs3 | Aggregate | geographies | variables | groups | sorts | examples | documentation | http://api.census.gov/data/2011/acs/acs3 |
