Springfield, Ohio
Springfield is a city in and the county seat of Clark County, Ohio, United States. Located in southwestern Ohio along the Mad River, the city had an estimated population of 58,281 in 2025[^c7], continuing a decades-long decline from a peak of 82,723 in 1960.
Founded in 1801 on the site of a Shawnee village, Springfield grew into a manufacturing powerhouse in the 19th and early 20th centuries. It was a national center of farm-equipment production—William Whiteley invented the self-raking reaper there in 1855[^c5]—and of rose cultivation, with more greenhouses producing roses than anywhere else in the world during the 1910s and 1920s[^c2]. By 1919, the city had 33 manufacturing plants employing 12,000 people[^c3].
Deindustrialization brought steep decline in the late 20th century: more than half the city's manufacturing jobs vanished between 1990 and 2024, and by 2016 the economic status of the Springfield metropolitan area had fallen more than that of any other metro area in the United States[^c4]. The city's poverty rate stood at 23.1 percent in 2024 and median household income at $47,143[^c8][^c9].
In the 2020s, an estimated 12,000 to 20,000 Haitian immigrants arrived in Clark County, drawn by manufacturing jobs and affordable housing[^c1]. The population grew by more than 20 percent in four years[^c6], straining public services and thrusting Springfield into the national political spotlight during the 2024 presidential election. The legal status of the Haitian community has been challenged in the U.S. Supreme Court, which heard arguments in 2026 on whether the Trump administration could end Temporary Protected Status for Haiti[^c10]. Meanwhile, the development of a large-scale data center in the city has drawn local opposition over environmental and utility cost concerns[^c11].
