TIGER/Line Shapefile, 2016,  nation, U.S., Current American Indian/Alaska Native/Native Hawaiian Areas National (AIANNH)
National

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 MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to
                                 stand alone as an independent data set, or they can be combined to cover the entire nation.  The American Indian/Alaska Native/Native
                                 Hawaiian (AIANNH) Areas Shapefile includes the following legal entities: federally recognized American Indian reservations and
                                 off-reservation trust land areas, state-recognized American Indian reservations, and Hawaiian home lands (HHLs).  The statistical
                                 entities included are Alaska Native village statistical areas (ANVSAs), Oklahoma tribal statistical areas (OTSAs), tribal designated
                                 statistical areas (TDSAs), and state designated tribal statistical areas (SDTSAs).  Joint use areas are also included in this shapefile
                                 refer to areas that are administered jointly and/or claimed by two or more American Indian tribes.  The Census Bureau designates both
                                 legal and statistical joint use areas as unique geographic entities for the purpose of presenting statistical data.  Note that tribal
                                 subdivisions and Alaska Native Regional Corporations (ANRCs) are additional types of American Indian/Alaska Native areas stored by the
                                 Census Bureau, but are displayed in separate shapefiles because of how they fall within the Census Bureau's geographic hierarchy.  The
                                 State of Hawaii's Office of Hawaiian Home Lands provides the legal boundaries for the HHLs. The boundaries for ANVSAs, OTSAs, and TDSAs
                                 were delineated for the 2010 Census through the Tribal Statistical Areas Program (TSAP) by participants from the federally recognized
                                 tribal governments.  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.  

                                 The boundaries for federally recognized American Indian reservations and off-reservation trust lands are as of January 1, 2016, as
                                 reported by the federally recognized tribal governments through the Census Bureau's Boundary and Annexation Survey (BAS).

                                 The boundaries for state-recognized American Indian reservations and for SDTSAs were delineated by a state governor-appointed liaisons
                                 for the 2010 Census through the State American Indian Reservation Program and TSAP respectively.
