FROM THE DIRECTOR
U.S. CENSUS BUREAU
This letter is to inform you that the U.S. Census Bureau is currently conducting the
Boundary Validation Program (BVP) in conjunction with the 2010 Boundary and
Annexation Survey (BAS). The BAS is conducted annually to collect information
about selected legally defined geographic areas, such as counties (and equivalent
areas), incorporated places, minor civil divisions (MCDs), all federally recognized
American Indian reservations and off-reservation trust land entities in the United
States, and municipios, barrios and subbarrios in Puerto Rico. The BVP is conducted
every ten years to provide the highest elected or appointed officials of local
governments an opportunity to review the boundary data collected during the BAS
over the last decade.
The BVP validates the following actions by local governmental units, as reported in
the BAS:
• The creation of newly incorporated places and MCDs
• The creation of new counties, and the addition of new federally recognized
American Indian areas (AIAs)
• The dissolution of incorporated places and MCDs
• The changes in the boundaries of incorporated places, MCDs, counties, barrios,
subbarrios, municipios, consolidated cities, and AIAs
The Census Bureau’s state boundary data will be reviewed in conjunction with
relevant counties boundaries as part of the BVP. No action on the BVP is required by
you. Final review and validation of Census Bureau boundary data will be complete in
July 2010. The Census Bureau will use the validated boundary information to
tabulate data from the 2010 Decennial Census and the American Community Survey.
If you have questions regarding the BVP or BAS, please email
, telephone (1-800-972-5651), or visit our website at
