Boundary and Annexation Survey

Subject: <YYYY> Boundary and Annexation Survey

The U.S. Census Bureau is now conducting the <YYYY> Boundary and Annexation Survey (BAS). Do not miss this annual opportunity to review and update the legal boundary, name, and status information the Census Bureau has for governments in your state.

BAS is a voluntary survey. However, we strongly encourage your participation for the following reasons:

• The Census Bureau uses boundary information for data collection, tabulation, and to issue the results of the decennial census, American Community Survey (ACS), Population Estimates Program (PEP), and many other censuses and surveys.

• The federal government distributes more than $2.8 trillion in funds annually for health, welfare, infrastructure, education, and other federal programs and services. Correct boundaries help make sure that governments receive proper funds and have the best data available for their decision-making processes.

To facilitate your review and potential updates, the BAS partnership shapefiles are now available on the Partnership Shapefiles webpage. Additionally, the BAS Partnership Toolbox works at the state-level enabling statewide change creation. If you have no boundary changes to report or need a Secure Web Incoming Module registration token to return your submission, email us at <geo.bas@census.gov>.
