Census Geography Reference

Geography Applications, Reference, and Maps

  • Geographic codes lookup provides convenient and definitive tables of commonly used geographic codes (mostly FIPS) organized by state for the U.S.
  • Geocorr (geographic correspondence engine), one of our oldest and most-used web applications, lets you generate geographic correspondence files showing how geographic areas overlap (e.g., how ZIP codes relate with counties or school districts). Geocorr 2014, the post-2010-census version, has current geography. Geocorr 2000 has post-2000-census geography, and Geocorr 1990 is still useful for the geography of the 1990s.
  • Geographic reference reports is where you'll find the PUMA reference reports and lots of other good stuff.
