2015 Cartographic Boundary File, State-County for United States, 1:5,000,000

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.

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 Census Bureau includes landmarks such as military installations in the MTDB for locating special features and to help enumerators
                                 during field operations.  In 2012, the Census Bureau obtained the inventory and boundaries of most military installations from the U.S.
                                 Department of Defense (DOD) for Air Force, Army, Marine, and Navy installations and from the U.S. Department of Homeland Security (DHS)
                                 for Coast Guard installations. 

                                 The military installation boundaries in this release represent the updates the Census Bureau made in 2012 in collaboration with DoD.

TIGER/Line Shapefile, 2016,  nation, U.S., Current Tribal Census Tract 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.

 A tribal census tract is a relatively permanent statistical subdivision of a federally recognized American Indian reservation and/or off-reservation trust land, delineated by the American Indian tribal government and/or the Census Bureau for the purpose of presenting demographic data. For the 2010 Census, tribal census tracts are defined independently of the standard county-based census tract  delineation. For federally recognized American Indian Tribes with reservations and/or off-reservation trust lands with a population less than 2,400, a single tribal census tract is defined. Qualifying areas with a population greater than 2,400 could define additional tribal census tracts within their area. The tribal census tract codes for the 2010 Census are six characters long with a leading "T" alphabetic character followed by a five-digit numeric code, for example, T01000, which translates as tribal census tract 10. Tribal block groups nest within tribal census tracts. Since individual tabulation blocks are defined within the standard State-county-census tract geographic hierarchy, a tribal census tract can contain seemingly duplicate block numbers, thus tribal census tracts cannot be used to uniquely identify census tabulation blocks for the 2010 Census. 

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

                                 The Topological Faces / Military Installation Relationship File (FACESMIL.dbf) contains a record for each face / military installation
                                 relationship.  Face refers to the areal (polygon) topological primitives that make up MTDB.  A face is bounded by one or more edges;
                                 its boundary includes only the edges that separate it from other faces, not any interior edges contained within the area of the face.
                                 The face to which a record in the Topological Faces / Military Installation Relationship File (FACESMIL.dbf) applies can be determined
                                 by linking to the Topological Faces Shapefile (FACES.shp) on the permanent topological face identifier (TFID) attribute.  The military
                                 installation to which a record in the Topological Faces / Military Installation Relationship File (FACESMIL.dbf) applies can be
                                 determined by linking to the Military Installation Shapefile (MIL.shp) on the military installation identifier (AREAID) attribute.  A
                                 face may be part of multiple military installations.  A military installation may consist of multiple faces.

TIGER/Line Shapefile, 2015,  state, Alaska, Current Alaska Native Regional Corporation (ANRC) State-based Shapefile

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. 
               
               ANRCs are corporations created according to the Alaska Native Claims Settlement Act (Pub. L. 92–203 ' 85 Stat.688 (1971); 43 U.S.C. 1602 et
               seq. (2000)). They are organized under the laws of the State of Alaska as "Regional Corporations," to conduct both the for  profit and
               non-profit affairs of Alaska Natives within defined regions of Alaska. The Census Bureau treats ANRCs as legal geographic entities.  Twelve ANRCs cover
               the entire State of Alaska except for the area within the Annette Island Reserve (an American Indian Reservation under the governmental authority of the
               Metlakatla Indian Community). There is a thirteenth ANRC that represents the eligible Alaska Natives living outside of Alaska that are not members of any
               of the twelve ANRCs within the State of Alaska. Because it has no defined geographic extent, this thirteenth ANRC does not appear in the TIGER/Line
               Shapefiles and the Census Bureau does not provide data for it. The Census Bureau offers representatives of the twelve ANRCs the opportunity to review and
               update the ANRC boundaries. ANRCs are represented by a 5 character FIPS code unique within Alaska and a nationally unique 8 character National Standard
               (GNIS)code.

               New England City and Town Area (NECTA) Divisions subdivide a NECTA containing a single core urban area that has a population of at least 2.5 million to
               form smaller groupings of cities and towns.  NECTA Divisions are defined by the Office of Management and Budget (OMB) and consist of a main city or town
               that represents an employment center, plus adjacent cities and towns associated with the main city or town through commuting ties.  Each NECTA Division
               must contain a total population of 100,000 or more.  Because NECTA Divisions represent subdivisions of larger NECTAs, it is not appropriate to rank or
               compare NECTA Divisions with NECTAs.  Not all NECTAs with urban areas of this size will contain NECTA Divisions. 

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

               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.

               within these districts.  The boundaries of the estates are primarily those of the former agricultural plantations that existed at the time Denmark
               transferred the islands to the United States in 1917.  The names and boundaries of the estates are in common usage by residents and in government
               administration.  The boundaries of the estates are as of January 1, 2010 and were provided to the Census Bureau by the USVI Office of the Lieutenant
               Governor.  Estates can be found in the Sub Minor Civil Division (submcd) shapefile for the 2010 and 2011 TIGER/Line products.
