The American Community Survey (ACS) is currently the largest household survey in the United States. The ACS is part of the 2010 Decennial Census Program and will eliminate the need for a long-form sample questionnaire. The ACS offers broad, comprehensive information on social, economic, and housing data and is designed to provide this information at many levels of geography, particularly for local communities. With full implementation in 2005, the ACS is now producing annual estimates for geographic areas with populations of 65,000 or more. Beginning in 2008, the ACS will release data for geographic areas with populations between 20,000 and 64,999 using data collected over the three-year period 2005 to 2007. Beginning in 2010, the ACS will use five-year period estimates to provide estimates for all areas down to census tracts/block groups.
Because of its detailed questionnaire and its experienced interviewing staff, the Current Population Survey (CPS) Annual Social and Economic Supplement (ASEC) is a high quality source of information used to produce the official annual estimate of poverty, and estimates of a number of other socioeconomic and demographic characteristics, including income, health insurance coverage, school enrollment, marital status, and family structure.
The following chart summarizes the key differences between the ACS and the CPS:
|American Community Survey||Current Population Survey|

|Time frame||Data collected continuously throughout calendar year with a previous 12-month reference period.||Data collected over a three-month period (February, March, and April) with a previous calendar year reference.|
|Geography||Single-year estimates provide data for the nation, states, counties, places (cities), congressional districts, American Indian and Alaska Native areas and all areas with a population of 65,000 or more.||Nation and states.|
|Sample size||250,000 addresses each month or about 3 million addresses a year.
||100,000 addresses over a three-month period.|
