OMB Control No.: 0607-0151
Expiration Date: 11-30-2021

A Message from the Director, U.S. Census Bureau:
The U.S. Census Bureau is now conducting the Boundary and Annexation Survey (BAS). The Census
Bureau and your state or county BAS representative are collaborating to consolidate responses to the
BAS. The representative has agreed to report all boundary updates, legal name changes, and status
updates to the Census Bureau. Please confirm your government’s BAS and Highest Elected Official (HEO)
contact information is correct using the website link below, and work with your state or county BAS
contact to ensure all boundary changes for your government are reported by your representative.
The BAS is a voluntary survey. We strongly encourage your participation in the BAS for the following
reasons:
•

Boundary updates complete the Census Bureau’s geographic framework for data collection,
tabulation, and dissemination, and are vital to the success of the decennial census, the
American Community Survey, Population Estimates Program, and many other censuses and
surveys.

•

The federal government allocates more than $675 billion in federal funds annually for health,
welfare, infrastructure, education, and other federal programs and services.

•

Responding to the BAS ensures that your local government receives the funds for which it is
entitled and has the best data available for its decision-making processes.
