Updated State Legislative and Congressional Districts

We're updating state legislative and Congressional districts due to 2020 redistricting.

District boundaries for the 118th Congress

When requesting congressional districts for the 118th Congress, Geocodio will use newly published redistricting data when available (please note that the boundaries are preliminary and not final for most states). Where new boundaries are not available, we will return the Congressional district based on 117th congress district boundaries instead.

The following states currently have updated boundaries for the 118th Congress. You must specifically request the 118th Congress in order to receive the new districts.

  • Arkansas
  • Colorado
  • Illinois
  • Indiana
  • Maine
  • Maryland
  • Montana
  • Nebraska
  • New York
  • North Carolina
  • Oregon
  • Texas
  • Utah
  • West Virginia
  • Wisconsin

Updated State Legislative district boundaries

stateleg-next is a preview of upcoming 2021 redistrict changes based on the 2020 census. Where available, the state legislative district returned will be based on newly redistricted boundaries. If new boundaries are not available, the current boundaries are used instead (effectively returning the same data as when the stateleg field append is used).

The following states have updated boundaries:

  • Colorado
  • Delaware
  • Illinois
  • Indiana
  • Maine
  • Nebraska
  • New York
  • North Carolina
  • Oklahoma
  • Oregon
  • Texas (State House only)
  • Utah
  • West Virginia (State House only)
  • Wisconsin

We are updating boundaries and adding new states as redistricting occurs and maps are published. The list will continue to be updated. Last change was made on 1/13/2022.
