Ohio is divided into 15 congressional districts, each represented by a member of the United States House of Representatives. 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.[2]
