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 for federally recognized
American Indian reservations, off-reservation trust land, and tribal subdivisions within the United States
effective on or before January 1 of the survey year. This voluntary survey is an important opportunity for
you to ensure that we have your correct boundary and legal name. The Census Bureau will use the
boundary information you provide to report data from 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
ACS. All annexation and boundary corrections received by May 31 will be included in BAS materials for
next year. BAS Respondent Guides, forms, maps and shapefiles are available for download from the
