OFFICE OF THE DIRECTOR

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 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 county, as well as the entities within 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.
We are pleased that you are willing to provide a response for the entities that agreed to
participate in the BAS consolidated agreement. Please respond to the BAS with information
regarding any boundary changes to those entities along with newly incorporated or
disincorporated places, and if applicable, created or deleted minor civil divisions.
The enclosed checklist contains information about the materials in your BAS package. These
materials reflect the response method that your county 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 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 .
Sincerely,

Thomas L. Mesenbourg, Jr.
