U.S. Census Boundary & Annexation Survey


The U.S. Census Bureau's Boundary and Annexation Survey (BAS) provides local governments with an opportunity to review the U.S. Census Bureau's legal boundary of each city, town, and county to ensure the Census Bureau has the correct boundaries. Maintaining correct boundaries helps ensure that the Census Bureau assigns the appropriate housing and population counts to each local government.

The information can also impact the amount of federal funding that may be available to jurisdictions. These resources fund our streets, highways, housing programs and other federally funded projects.
