- description: The 2014 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. The records in this file allow users
to map the parts of Urban Areas that overlap a particular county. 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. Counties are 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, 2010.; abstract: The 2014 cartographic boundary KMLs are simplified
