If you are interested in the congressional districts for a particular state that aren't posted on our site, you can either download a national map by following the instructions below and filter out the states you don't need or you can follow the instructions in the "Where to Find: State Election Results or Precinct Shapefiles" article.

To download a national file, navigate to https://catalog.data.gov/organization/census-gov and search for the particular congress you are interested. Be sure to remember that district lines can (and often do) change more than every 10 years, so to ensure you download the right file, be sure to check the years.
