Geography Mapping Files

GIS mapping files contain geographical information, which are spatial data encoded into a file format.   

Examples include:

  • Shapefiles (Partnership, TIGER/Line, Cartographic Boundary)
  • KML (Google)
  • Geodatabase (ESRI) files.

We use Partnership Shapefiles in our partner programs to share data with and capture data from our partners.

TIGER/Line Shapefiles do not include demographic data, but they do contain geographic entity codes (GEOIDs) that can be linked to the Census Bureau’s demographic data, available on American FactFinder.

Cartographic boundary files are specifically designed for small scale thematic mapping.

For help determining which product is right for you, please see our TIGER Data Products Guide.
