Cartographic Boundary Files

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. As of 2019, cartographic boundary files are available in shapefile, geodatabase, and 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.

Cartographic Boundary Files

ZIP Code Tabulation Areas (ZCTAs), Public Use Microdata Areas (PUMAs), and Urban Areas (UAs) are delineated on different schedules than the geographic areas available below to support data dissemination. We will recreate and repost all layers at two other points in the future so that all files posted at any given time will align with one another.

To learn more about the filenames, please see:
