American Indian and Alaska Native areas maps

The Tribal Statistical Areas Program (TSAP), a decennial program of the U. S. Census Bureau, is part of an ongoing effort to enhance the reporting of meaningful statistical data for American Indian and Alaska Native areas. Through the program, tribes have the opportunity to identify and delineate the geographic statistical areas and block boundaries for which the Census Bureau will tabulate 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. Statistical data from the 1990 and 2000 decennial censuses can be found on the Census Bureau’s American Factfinder web site.

The program specifically provides for the review and delineation of:

* Alaska Native village statistical areas (ANVSAs)
* Oklahoma tribal statistical areas (OTSAs)
* OTSA Tribal subdivisions
* Tribal designated statistical areas (TDSAs)
* State designated tribal statistical areas (SDTSAs)
* Tribal census tracts (on federally recognized reservations only)
* Tribal block groups (on federally recognized reservations only)
* Census designated places (CDPs)

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