Importing Districts

Viewing Congressional Districts

To view 2020, 2022, or 2024 congressional districts, select the Use Official Map option in the right sidebar of the map browser. There you can select the year and state you’d like to view the congressional districts for, click Open map, and they will be loaded into Redistricter.

Importing shapefiles

If you’d like to view districts that aren’t 2020-2024 congressional districts or are custom made districts from outside of Redistricter, you can import the shapefile for those districts into Redistricter. The shapefiles for most legislative districts can usually be found by googling “state year legislature shapefile”.

Then on the map browser select the Import shapefile button in the top right corner, select the relevant state, upload the shapefile, and click Import map.

Currently only .json, .shp, and .geojson shapefile types are accepted.

Troubleshooting Imports

If an error occurs and the imported map fails to load, verify that the uploaded file is indeed a shapefile. This can be checked by importing the file into Mapshaper to see if it displays a map. Additionally, ensure the shapefile is projected by loading the shapefile into Mapshaper and typing -proj wgs84 into the command bar. An error message will appear if there’s no projection.
