TIGER county boundary file for 2018
The TIGER/Line Shapefiles are the fully supported, core geographic product from the U.S. Census
Bureau. They are extracts 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. The shapefiles include information for the fifty states, the District of Columbia,
Puerto Rico, and the Island areas (American Samoa, the Commonwealth of the Northern Mariana
Islands, Guam, and the United States Virgin Islands). The shapefiles include polygon boundaries of
geographic areas and features, linear features including roads and hydrography, and point features. They
do not contain any sensitive data.
