Description
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.
Divisions are groupings of states within a census geographic region, established by the Census Bureau for the presentation of census
data. The current nine divisions (East North Central, East South Central, Middle Atlantic, Mountain, New England, Pacific, South
Atlantic, West North Central, and West South Central) are intended to represent relatively homogeneous areas that are subdivisions of
the four census geographic regions.
