FROM THE DIRECTOR
U.S. CENSUS BUREAU
The U.S. Census Bureau conducts the annual 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 to report data from the Population Estimates Program (PEP), the
American Community Survey (ACS), and other Census programs and surveys.
The Census Bureau and your state or county are collaborating to consolidate responses to the BAS. The
state or county 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 has agreed to participate in this consolidation of work, we will
not be sending you separate BAS materials.
If you have questions about what will be submitted for your government to the Census Bureau, please
contact your county or state representative below.
Please confirm your contact information above. Submit changes via e-mail to
or submit online.
The Census Bureau appreciates your response to this important voluntary survey. If you need any
assistance with this request, please e-mail , telephone 1–800–972–5651, or
visit .
Sincerely,

Thomas L. Mesenbourg, Jr.
Acting DIrector
