TIGER/Line Shapefile, 2016,  nation, U.S., Current American Indian Tribal Subdivision (AITS) 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.

 
American Indian tribal subdivisions are administrative subdivisions of federally recognized American Indian reservations/off-reservation trust lands or Oklahoma tribal statistical areas (OTSAs).  These entities are internal units of self-government and/or administration that serve social, cultural, and/or economic purposes for the American Indian tribe or tribes on the reservations/off-reservation trust lands or OTSAs.  The Census Bureau obtains the boundary and attribute information for tribal subdivisions on federally recognized American Indian reservations and off-reservation trust lands from federally recognized tribal governments through the Census Bureau's Boundary and Annexation Survey (BAS).  For the 2010 Census, the boundaries for tribal subdivisions on OTSAs were also obtained from federally recognized tribal governments through the Tribal Statistical Areas Program (TSAP).  Note that tribal subdivisions do not exist on all reservations/off-reservation trust lands or OTSAs, rather only where they were submitted to the Census Bureau by the federally recognized tribal government for that area.  

 
The boundaries for American Indian tribal subdivisions are as of January 1, 2015, as reported by the federally recognized tribal governments through the Census Bureau's Boundary and Annexation Survey (BAS).

 
The boundaries for tribal subdivisions on OTSAs are those reported as of January 1, 2010 through TSAP.

TIGER/Line Shapefile, 2016,  nation, U.S., Current Metropolitan Statistical Area/Micropolitan Statistical Area (CBSA) 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.


Metropolitan and Micropolitan Statistical Areas are together termed Core Based Statistical Areas (CBSAs) and are defined by the Office of Management and Budget (OMB) and consist of the county or counties or equivalent entities associated with at least one urban core (urbanized area or urban cluster) of at least 10,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties with the counties containing the core.  Categories of CBSAs are: Metropolitan Statistical Areas, based on urbanized areas of 50,000 or more population; and Micropolitan Statistical Areas, based on urban clusters of at least 10,000 population but less than 50,000 population.  


The CBSAs boundaries are those defined by OMB based on the 2010 Census and published in 2013.

                                 The primary legal divisions of most states are termed counties.  In Louisiana, these divisions are known as parishes.  In Alaska, which
                                 has no counties, the equivalent entities are the organized boroughs, city and boroughs, municipalities, and for the unorganized area,
                                 census areas.  The latter are delineated cooperatively for statistical purposes by the State of Alaska and the Census Bureau.  In four
                                 states (Maryland, Missouri, Nevada, and Virginia), there are one or more incorporated places that are independent of any county
                                 organization and thus constitute primary divisions of their states.  These incorporated places are known as independent cities and are
                                 treated as equivalent entities for purposes of data presentation.  The District of Columbia and Guam have no primary divisions, and
                                 each area is considered an equivalent entity for purposes of data presentation.  The Census Bureau treats the following entities as
                                 equivalents of counties for purposes of data presentation: Municipios in Puerto Rico, Districts and Islands in American Samoa,
                                 Municipalities in the Commonwealth of the Northern Mariana Islands, and Islands in the U.S. Virgin Islands.  The entire area of the
                                 United States, Puerto Rico, and the Island Areas is covered by counties or equivalent entities.  

                                 The boundaries for counties and equivalent entities are as of January 1, 2015, primarily as reported through the Census Bureau's
                                 Boundary and Annexation Survey (BAS).

Series Information File for the 2015 Cartographic Boundary File,  State-Consolidated City , 1:500,000

The 2015 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files.

A consolidated city is a unit of local government for which the functions of an incorporated place and its county or minor civil division (MCD) have merged.  This action results in both the primary incorporated place and the county or MCD continuing to exist as legal entities, even though the county or MCD performs few or no governmental functions and has few or no elected officials.  Where this occurs, and where one or more other incorporated places in the county or MCD continue to function as separate governments, even though they have been included in the consolidated government, the primary incorporated place is referred to as a consolidated city.  The Census Bureau classifies the separately incorporated places within the consolidated city as place entities and creates a separate place (balance) record for the portion of the consolidated city not within any other place.

                                 Primary roads are generally divided, limited-access highways within the interstate highway system or under State management, and are
                                 distinguished by the presence of interchanges.  These highways are accessible by ramps and may include some toll highways.  The

In New England (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont), the Office of Management and Budget (OMB) has defined an alternative county subdivision (generally cities and towns) based definition of Core Based Statistical Areas (CBSAs) known as New England City and Town Areas (NECTAs).  NECTAs are defined using the same criteria as Metropolitan Statistical Areas and Micropolitan Statistical Areas and are identified as either metropolitan or micropolitan, based, respectively, on the presence of either an urban area of 50,000 or more population or an urban cluster of at least 10,000 and less than 50,000 population.  A NECTA containing a single core urban area with a population of at least 2.5 million may be subdivided to form smaller groupings of cities and towns referred to as NECTA Divisions.  

The NECTAs for the 2010 Census are those defined by OMB and published in 2013.

After each decennial census, the Census Bureau delineates urban areas that represent densely developed territory, encompassing residential, commercial, and other nonresidential urban land uses.  In general, this territory consists of areas of high population density and urban land use resulting in a representation of the "urban footprint."  There are two types of urban areas: urbanized areas (UAs) that contain 50,000 or more people and urban clusters (UCs) that contain at least 2,500 people, but fewer than 50,000 people (except in the U.S. Virgin Islands and Guam which each contain urban clusters with populations greater than 50,000).  Each urban area is identified by a 5-character numeric census code that may contain leading zeroes.

A tribal block group is a cluster of census tabulation blocks within a single tribal census tract delineated by American Indian tribal participants or the Census Bureau for the purpose of presenting demographic data on their reservation and/or off-reservation trust land.  The tribal block groups are defined independently of the standard county-based block group delineation.  For federally recognized American Indian Tribes with reservations and/or off-reservation trust lands with a population less than 1,200, a single tribal block group is defined.  Qualifying reservations and/or off-reservation trust lands with a population greater than 1,200 could define additional tribal block groups within their area without regard to the standard block group configuration.  Tribal block groups do not necessarily contain tabulation blocks always beginning with the same number and could contain seemingly duplicate block numbers.  Tabulation block numbers are still assigned by using standard block groups, not the tribal block groups.  To better identify tribal block groups, the letter code range A through K (except I, which could be confused with a number 1) is used uniquely within each tribal census tract.  


The boundaries of tribal block groups and tribal census tracts are those delineated through the Tribal Statistical Areas Program (TSAP) for the 2010 Census.
