The Tribal Statistical Areas Program (TSAP), a decennial program of the U. S. Census Bureau, was part of an ongoing effort to enhance the reporting of meaningful statistical data for American Indian and Alaska Native areas.  Through the program, tribes had the opportunity to identify and delineate the geographic statistical areas and block boundaries for which the Census Bureau tabulates data for the 2010 Census and the ongoing American Community Survey (ACS) after 2010.  Statistical data from the 2010 Census and the ACS post-2010 can provide tribes with a meaningful tool to help make informed decisions, and plan for services such as education, health, and housing.

The program specifically provides for the review and delineation of:

• Alaska Native village statistical areas (ANVSAs)
• Census designated places (CDPs)
• Oklahoma tribal statistical areas (OTSAs)
• OTSA Tribal subdivisions
• State designated tribal statistical areas (SDTSAs)
• Tribal designated statistical areas (TDSAs)
• Tribal census tracts
• Tribal block groups

In addition during the 2010 Census, TSAP also worked with state recognized American Indian tribes to review and delineate State American Indian reservations (SAIRs).

The Federal Register Notices from the 2010 TSAP program can be found on our Federal Register Notices page.

The Participant Statistical Areas Program was a geographic program within the 2010 Decennial Census Program that offered regional and local participants the opportunity to review and update, if necessary, statistical geographic entities for use in tabulating and publishing data from Census 2010, the American Community Survey (ACS), and potentially other censuses and surveys. The four statistical geographic entities included in the PSAP were county-based census tracts, block groups, census designated places (CDPs), and census county divisions (CCDs) (including census subareas in Alaska). The PSAP and the TSAP are parallel geographic programs. The primary participants in PSAP were organizations representing regional groupings of governments. Tribes worked with the primary PSAP participant(s) for their area of interest to help ensure that tribal data needs were met through the statistical geographic entities defined via the PSAP as well as via the TSAP. For example, a CDP delineating an unincorporated community located off of an AIR, ORTL, or OTSA for which data would be useful for a tribe was defined via the PSAP, not the TSAP.
