Dayton anchors Montgomery County, a longtime bellwether corridor where deindustrialization reshaped the electorate across decades; the city's majority-minority population and persistently high poverty rate make it a key variable in statewide urban-turnout calculations.
Across the recorded series it reached a Democratic high of 51.3 points in 2012. Between 2020 and 2024 the city moved 4.3 points toward the Republican candidate; the 2024 margin was 36.8 points.
A population of 136,579, a 50% non-Hispanic-white share, and a median household income of $45,247 describe the city. The city's voting pattern over the last decade is most similar to that of Akron and Detroit.
