The cartographic boundary files are simplified representations of selected geographic areas from the Census Bureau’s MAF/TIGER geographic database. These boundary files are specifically designed for small scale thematic mapping.
The cartographic boundary files are available in shapefile and Keyhole Markup Language (KML) format. KML is a file format used to display geographic data in a tool such as Google Earth or Google Maps. For shapefile versions of these files, please see our Cartographic Boundary Files - Shapefile page.
For more details about these files, please see our Cartographic Boundary File Description page.
To access files for data year 2019 and after, please visit our new Cartographic Boundary File page.
