Springfield, Ohio
Springfield is the seat of [[Clark County]], Ohio, in the west-central part of the state on Buck Creek and Mad River, 25 miles northeast of Dayton[^c1]. The city was laid out in 1801, incorporated as a village in 1827, and incorporated as a city in 1850[^c3].
Economy
Farm machinery manufacturing, which began in 1855 when William Whiteley invented a successful reaper and mower, was for many years a leading industry[^c2]. The industrial base later diversified into buses, heavy trucks, hoisting machinery, and metal products. In 2025, construction began on a $1.3 billion AI data center at Prime Ohio corporate park, a technology investment expected to create 120 jobs[^c12]. The loss of 22,000 blue-collar jobs in Clark County during the 1990s, combined with a 27 percent decline in median incomes between 1999 and 2014, marked a prolonged period of economic decline[^c7]. The poverty rate stood at 23.1 percent, and median household income was $47,143[^c8][^c9].
As of 2026, the Springfield metropolitan area employed approximately 47,000 workers. The largest employment sectors were trade, transportation, and utilities (9,100 jobs); education and health services (7,700); government (7,100); manufacturing (6,100); and professional and business services (6,000)[^c10]. Within the city limits, the largest industries were manufacturing (4,468 jobs), health care and social assistance (3,809), and retail trade (2,657)[^c11].
Government
Springfield operates under a commission-manager form of government, adopted by charter on August 26, 1913[^c5]. An elected five-member commission sets policy and appoints a professional city manager to oversee day-to-day operations.
Demographics
The city's population was estimated at 58,281 in 2025[^c4], down from a peak of more than 80,000 in the 1970s. Beginning around 2020, an estimated 10,000 to 15,000 Haitian immigrants arrived in Clark County, drawn by low cost of living and available work, now representing roughly 25 percent of the city's population[^c6].
