Ohio's 1st congressional district is represented by Democrat Greg Landsman. The district includes the city of Cincinnati, all of Warren County and borders the state of Kentucky. This district was once represented by President William Henry Harrison. After redistricting in 2010, the district was widely seen as heavily gerrymandered by state Republicans to protect the incumbent, Steve Chabot. Chabot lost the seat in 2022 to Landsman, after redistricting unified the city of Cincinnati into the district. The city was previously split between the 1st and 2nd districts.

The district is somewhat more Democratic than its predecessor even though it includes heavily Republican Warren County. Previous iterations of the district (before 2013) did not include Warren County. However, Hamilton County has double Warren County's population, creating a marginally Democratic seat.

Demographics

According to the APM Research Lab's Voter Profile Tools (featuring the U.S. Census Bureau's 2019 American Community Survey), the district contained about 551,000 potential voters (citizens, age 18+). Of these, 74% are White and 21% are Black. Immigrants make up 4% of the district's potential voters. Median income among households (with one or more potential voter) in the district is about $64,000, while 11% of households live below the poverty line. 8% of those 25 and older have not earned a high school degree, while 34% hold a bachelor's or higher degree.

Composition

For the 118th and successive Congresses (based on redistricting following the 2020 census), the district contains all or portions of the following counties, townships, and municipalities:

Hamilton County (27)

: Amberley, Anderson Township, Arlington Heights, Blue Ash, Cincinnati, Columbia Township, Deer Park, Delhi Township, Elmwood Place, Evendale, Fairfax, Golf Manor, Loveland (part; also 2nd and 8th; shared with Clermont and Warren counties), Madeira, Mariemont, Milford (part; also 2nd; shared with Clermont County), Montgomery, Newtown, Norwood, Reading, Sharonville (part; also 8th), Silverton, St. Bernard, Symmes Township, Syracuse Township, Terrace Park, The Village of Indian Hill
