A Message from the Director, U.S. Census Bureau...
The U.S. Census Bureau (Census Bureau) conducts the Boundary and Annexation Survey
(BAS) to update our records regarding changes to legal boundaries, names, and governmental
status of all governmental units effective on or before January 1 of the survey year. This
voluntary survey is an important opportunity for you to ensure that we have the correct
boundary and legal name for your government. The Census Bureau will use the boundary
information you provide to report data from the Population Estimates Program (PEP), the
American Community Survey (ACS), and other Census Bureau programs and surveys.
The Census Bureau and your state or county representative are collaborating to consolidate
responses to the BAS. The representative has agreed to report all governmental annexations,
deannexations, incorporations, disincorporations, and mergers for the governments effective on
or before January 1 of the survey year to the Census Bureau. Since your government is
participating in this consolidation of work, we will not be sending you separate BAS materials.
Please work with your state or county BAS contact to ensure all boundary changes are
reported to the BAS.
For state reporting requirements, please visit the BAS Web page at the following link:

Please confirm your contact information above for the Highest Elected Official and submit changes via email
to or submit online at https://www.census.gov/geo/partnerships/bas/bas_ar_form.html
If you have questions about what will be submitted for your government to the Census Bureau, please contact
your representative:
