Redistricting in Indiana

Here’s how new congressional maps shift voting power in every state

Every 10 years, states redraw the boundaries of their congressional districts to reflect new population counts from the census. Indiana Republicans drew a new congressional map that doesn’t dramatically change the state’s district lines, but does strengthen Republicans’ hand.

The most significant change was making the 5th District in the northern Indianapolis suburbs much more Republican. Previously, it had been the most competitive district in the state and had been trending toward Democrats.

How the new map shifts voting power by demographic

Indiana’s new map is very similar to the old one. It will continue to have nine seats in the House. In eight of Indiana’s congressional districts, the majority of residents are White. In one district — the 7th District, which is home to Indianapolis — no demographic group represents a majority.
