2015 Cartographic Boundary File, Region for United States, 1:5,000,000

The 2015 cartographic boundary KMLs 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.

                                 Regions are four groupings of States (Northeast, South, Midwest, and West) established by the Census Bureau in 1942 for the
                                 presentation of census data.

2015 Cartographic Boundary File, American Indian Area/Alaska Native Area/Hawaiian Home Land for United States, 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.

The American Indian/Alaska Native/Native Hawaiian (AIANNH) Areas cartographic boundary file includes generalized versions of 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 files because of how they fall within the Census Bureau's geographic hierarchy.

TIGER/Line Shapefile, 2015,  nation, U.S., Military Installation National 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.

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.

2015 Cartographic Boundary File, Metropolitan Statistical Area/Micropolitan Statistical Area 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.

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.

                                 Combined Statistical Areas (CSAs) are defined by the Office of Management and Budget (OMB) and consist of two or more adjacent Core
                                 Based Statistical Areas (CBSAs) that have significant employment interchanges.  The CBSAs that combine to create a CSA retain separate
                                 identities within the larger CSA.  Because CSAs represent groupings of CBSAs, they should not be ranked or compared with individual
                                 CBSAs.

2015 Cartographic Boundary File, 5-Digit ZIP Code Tabulation Area for United States, 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.

ZIP Code Tabulation Areas (ZCTAs) are approximate area representations of U.S. Postal Service (USPS) ZIP Code service areas that the Census Bureau creates to present statistical data for each decennial census. The Census Bureau delineates ZCTA boundaries for the United States, Puerto Rico, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands once each decade following the decennial census. Data users should not use ZCTAs to identify the official USPS ZIP Code for mail delivery. The USPS makes periodic changes to ZIP Codes to support more efficient mail delivery.

The Census Bureau uses tabulation blocks as the basis for defining each ZCTA. Tabulation blocks are assigned to a ZCTA based on the most frequently occurring ZIP Code for the addresses contained within that block. The most frequently occurring ZIP Code also becomes the five-digit numeric code of the ZCTA. These codes may contain leading zeros.

Blocks that do not contain addresses but are surrounded by a single ZCTA (enclaves) are assigned to the surrounding ZCTA. Because the Census Bureau only uses the most frequently occurring ZIP Code to assign blocks, a ZCTA may not exist for every USPS ZIP Code. Some ZIP Codes may not have a matching ZCTA because too few addresses were associated with the specific ZIP Code or the ZIP Code was not the most frequently occurring ZIP Code within any of the blocks where it exists.

The generalized ZCTA boundaries in this file are based on those delineated following the 2010 Census.

                                 The Coastline Shapefile includes all features within the MTDB Class "Coastline" distinguished where the MAF/TIGER Feature
                                 Classification Code (MTFCC) for the feature in MTDB is L4150. The coastline included in this shapefile was delineated by the Census
                                 Bureau in the MAF/TIGER database based on water measurement class for display of statistical information only; its depiction and
                                 designation for statistical purposes does not constitute a determination of jurisdictional authority or rights of ownership or
                                 entitlement and it is not a legal land description. This shapefile should be used for data presentation purposes only.  It is not the
                                 official source for the coastline feature. The name assigned to each Coastline feature is a short form of the name of the large body of
                                 water bordered by this Coastline feature.

Congressional Districts are the 435 areas from which people are elected to the U.S. House of Representatives.  After the apportionment of congressional seats among the states based on census population counts, each state is responsible for establishing congressional districts for the purpose of electing representatives.  Each congressional district is to be as equal in population to all other congressional districts in a state as practicable.  The 114th Congress is seated from January 2015 to 2017. The cartographic boundary files for the District of Columbia, Puerto Rico, and the Island Areas (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands) each contain a single record for the non-voting delegate district in these areas.  The boundaries of all other congressional districts are provided to the Census Bureau through the Redistricting Data Program (RDP).

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.
