Resource Abstract:
- description: 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 records in this file allow users
to map the parts of the 114th Congressional Districts that overlap a particular county. 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 TIGER/Line shapefiles 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. The boundaries for counties and equivalent entities are mostly as of January 1, 2013, primarily as reported through
the Census Bureau's Boundary and Annexation Survey (BAS). However, some changes made after January 2013, including the
addition and deletion of counties, are included.; abstract: The 2015 cartographic boundary shapefiles are simplified representations
