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 2020 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, 2020, 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 2020 Census through the State American Indian Reservation Program and TSAP
respectively.
In order for others to use the information in the Census MAF/TIGER database in a
geographic information system (GIS) or for other geographic applications, the Census
Bureau releases to the public extracts of the database in the form of TIGER/Line
Shapefiles.

Accurate against National Standard Codes, Federal Information Processing (FIPS)
and the Geographic Names Information System (GNIS) at the 100% level for the codes and
base names. The remaining attribute information has been examined but has not been fully
tested for accuracy.
The Census Bureau performed automated tests to ensure logical consistency and limits of
shapefiles. Segments making up the outer and inner boundaries of a polygon tie end-to-end
to completely enclose the area. All polygons are tested for closure. The Census Bureau uses
its internally developed geographic update system to enhance and modify spatial and
attribute data in the Census MAF/TIGER database. Standard geographic codes, such as FIPS
codes for states, counties, municipalities, county subdivisions, places, American
Indian/Alaska Native/Native Hawaiian areas, and congressional districts are used when
encoding spatial entities. The Census Bureau performed spatial data tests for logical
consistency of the codes during the compilation of the original Census MAF/TIGER database
files. Most of the codes for geographic entities except states, counties, urban areas, Core
Based Statistical Areas (CBSAs), American Indian Areas (AIAs), and congressional districts
were provided to the Census Bureau by the USGS, the agency responsible for maintaining the
Geographic Names Information System (GNIS). Feature attribute information has been examined
but has not been fully tested for consistency. For the TIGER/Line Shapefiles, the Point and
Vector Object Count for the G-polygon SDTS Point and Vector Object Type reflects the number
of records in the shapefile attribute table. For multi-polygon features, only one attribute
record exists for each multi-polygon rather than one attribute record per individual
G-polygon component of the multi-polygon feature. TIGER/Line Shapefile multi-polygons are
an exception to the G-polygon object type classification. Therefore, when multi-polygons
exist in a shapefile, the object count will be less than the actual number of
G-polygons.
Data completeness of the TIGER/Line Shapefiles reflects the contents of the Census
MAF/TIGER database at the time the TIGER/Line Shapefiles were created.
