FROM THE DIRECTOR
U.S. CENSUS BUREAU
The U.S. Census Bureau conducts the Boundary and Annexation Survey (BAS) to update
our records regarding changes to legal boundaries, names, and 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 jurisdiction. 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 programs and surveys.
The enclosed checklist contains information about the materials in your BAS package.
These materials reflect the response method that your jurisdiction previously requested.
Information describing how to update the enclosed materials is available in the BAS
Respondent Guide. This information is also provided on the BAS Web site at
.
All annexations received by March 1 will be included in this year’s boundary delivery for
the PEP and the ACS. All annexation and boundary corrections received by May 31 will be
included in your BAS materials for next year. The Census Bureau will attempt to include
street and landmark updates as resources permit. Please note that your response to the
BAS does not replace any state or county reporting requirement.
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 our Web site at .
Sincerely,

Thomas L. Mesenbourg, Jr.
Acting Director
