Abstract
The U.S. Census Bureau’s American Community Survey (ACS) is part of the 2010 Decennial Census Program. The ACS is a nationwide survey that provides annually updated, detailed demographic, socioeconomic, and housing information for communities across the United States and Puerto Rico.
By its sample design, the ACS accumulates independent monthly sample data as time passes. This allows for the release of estimates for smaller geographic areas once enough sample has been accumulated.

The 2008 ACS will provide data for a set of geographic areas with a total population of 65,000 or more. The annual sample size expanded from about 800,000 addresses in 1,240 counties in 2004 to approximately 3 million addresses in 3,357 U.S. school districts in 2008. As a result, the 2008 ACS data provide information for many geographic areas that did not receive ACS data in previous years.
