Resource Abstract:
- description: 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 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 presentationMunicipios 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 TIGER/Line shapefiles and related
