Ohio's congressional districts

After the 2010 census, Ohio, which up until then had 18 districts, lost two House seats due to slow population growth compared to the national average,[1] and a new map was signed into law on September 26, 2011.

Starting in the 2022 midterms, per the 2020 United States census, Ohio lost its 16th congressional seat, ending up with its current 15 districts.

Neither the state legislature nor the Ohio Redistricting Commission responded to the court's order to redraw the map.

In the 2022 general election, Republicans won the seat occupied by the retiring Chief Justice Maureen O'Connor, swinging the court toward the faction that had dissented from the earlier opinions.

[17] A 2024 citizen ballot initiative spearheaded by O'Connor, proposing to wrest legislative and Congressional redistricting power away from Ohio politicians into a citizen redistricting commission and enforce strict proportionality failed essentially along party lines, based on analysis of county- and precinct-level voting results on the issue relative to U.S. Presidential voting.
