Boundary and Annexation Survey

E-mail: BAS-E-SDC - BAS Announcement: State Data Center

Subject: <YYYY> Boundary and Annexation Survey–SDC

The U.S. Census Bureau is now conducting the <YYYY> Boundary and Annexation Survey (BAS). BAS provides participants an opportunity to review and update the legal boundary, name, and status information the Census Bureau has for their government.

BAS is a voluntary survey. However, we strongly encourage tribal, state, and general-purpose local governments to participate in BAS 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.

ACTION STEPS

• Remind governments in your state to review their boundaries and participate in BAS. Governments can respond using the interactive, online BAS Annual Response Form and their BAS ID.

• Encourage participation in BAS training webinars for those unfamiliar with the program. The webinar schedule, webinar recordings, and registration instructions are on the BAS Webinars webpage.

KEY DATES

January 1 Legal boundary changes must be in effect on or before this date to be reported in the current survey year.
