The U.S. Census Bureau is sending you this email to acknowledge and thank you for your recent
response to the Boundary and Annexation Survey (BAS). Your government has indicated that there are
boundary changes to report, however we have not yet received these changes.
Action Step:
•

Submit boundary changes to the Census Bureau. On the BAS website, you will find detailed
information on how to report updates to the BAS digitally or using paper maps. There you will
find respondent guidelines, the Geographic Update Partnership Software (GUPS), the BAS
partnership tools, partnership shapefiles, paper maps, previous annexation data, and other
important documentation.
NOTE: Please respond to the BAS with a “No Changes” response if, after reviewing your
government’s boundaries, you determine there are no boundary changes to report. If you do
not respond, we will contact your government to confirm your boundary change status.
