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 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 programs and surveys.
The Census Bureau is requesting that your governmental unit review your boundary online
and respond to the survey online or return the
enclosed Annual Response Form. Place an "X" in the appropriate box to indicate whether your governmental unit has boundary changes to report. If your governmental unit has changes to report, place an "X"
in the box next to your preferred submission method. The Census Bureau will only ship maps and other
materials to governments who request them. For an explanation of the various submission methods, please
refer to the reverse side of the Annual Response Form. Confirm that all contact information is correct.
Respond online, or fax the completed form to the Census Bureau before February 15 using the toll-free
number, 1–800–416–3262. Fax the form only. Please do not include a cover sheet. You may also mail the
form to the Census Bureau in the enclosed postage-paid envelope or send by e-mail to
.
If your governmental unit has boundary changes to report, please submit them to the Census Bureau by
March 1. 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 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
requirements. BAS Respondent Guides, forms, maps, and shapefiles are available for download from the
Census Web site .
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
