Cartographic Boundary Files

The cartographic boundary files are simplified representations of selected geographic areas from the Census Bureau’s Master Address File/Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) System. These boundary files are specifically designed for small scale thematic mapping. As of 2019, cartographic boundary files are available in shapefile, geodatabase, and Keyhole Markup Language (KML) format. For more details about these files, including their appropriate usage, please see our Cartographic Boundary File Description page.

You can find older files on the Cartographic Boundary File - Shapefiles and Cartographic Boundary File - KMLs pages. You can also download files directly from our FTP site.
