OMB Control No.: 0607-0151
Expiration Date: 11-30-2023

A Message from the Director, U.S. Census Bureau:
The U.S. Census Bureau is now conducting the Boundary and Annexation Survey (BAS). Your state,
county, or county equivalent government collaborates with the Census Bureau to provide a BAS
response on your government’s behalf. The Consolidated BAS (CBAS) representative reports all legal
boundary, name, and status updates to the Census Bureau. Please work with your CBAS contact to
ensure all boundary changes for your government are reported to BAS. Participants may also provide
updates to census designated places.
BAS is a voluntary survey. We strongly encourage your participation in BAS for the following reasons:
•

The Census Bureau uses this boundary information for data collection, tabulation, and
dissemination for the decennial census, American Community Survey (ACS), Population
Estimates Program (PEP), 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. Correct boundaries
ensure governments receive funds appropriately and have the best data available for their
decision-making processes.

Action Step:
•
