This dataset contains all the proper names and boundaries of American Indian reservations in Arizona. Data was provided by the US Census Bureau.

The TIGER/Line Shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The American Indian/Alaska Native/Native Hawaiian (AIANNH) Areas in Arizona Shapefile includes the following legal entities: federally recognized American Indian reservations and off-reservation trust land areas, and state-recognized American Indian reservations. The Bureau of Indian Affairs (BIA) within the U.S. Department of the Interior (DOI) provides the list of federally recognized tribes and only provides legal boundary information when the tribes need supporting records, if a boundary is based on treaty or another document that is historical or open to legal interpretation, or when another tribal, state, or local government challenges the depiction of a reservation or off-reservation trust land.
