Geography Partnership Programs

We foster partnerships with tribal, federal, state, and local governments as well as commercial partners. Find information about specific partnership programs and learn more about our partnerships with other organizations.

To learn how tribal, state, and local governments participate in geography partnership programs and why participation benefits your community, please view this short video and flyer [PDF].

American Indian and Alaska Native Programs

The U.S. Census Bureau has two main programs designed to collect and maintain geographic information on tribal areas.
Boundary and Annexation Survey (BAS)

The Census Bureau conducts the BAS annually to collect information about selected legally defined geographic areas.
Local Update of Census Addresses (LUCA) Operation

LUCA is the only opportunity offered to tribal, state, and local governments to review and comment on the residential address list for their jurisdiction.
Participant Statistical Areas Program (PSAP)

Enables invited participants to review and verify selected statistical area boundaries for Census data tabulation following specific guidelines and criteria.
