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.
