What stands out
Where this county sits among Ohio's 88 on the measures the atlas tracks, and the sentences the inference engine built from them. Rankings and associations only: nothing here says one measure causes another, and a county-level pattern is not a fact about anyone who lives here.
- measures flagged for this county
- 7
- 6 in the worst tenth of the 88
- of the 85 counties with anything flagged
- 40th worst
- economy, health, safety
- losing ground on Ohio
- 2
- the gap to the state is widening
- peer group the engine compares it against
- small metro and micropolitan
"Losing ground on Ohio" compares trends, not levels: a county can be losing ground while its own number improves, if the rest of the state improved faster over the same years.

How Clark County began
Clark County was organized by the Ohio General Assembly on March 1, 1818, from parts of Champaign, Greene and Madison counties, and named for General George Rogers Clark, the Revolutionary War officer whose 1780 campaign against the Shawnee town of Peckuwe (Piqua) on the Mad River had opened this ground to Euro-American settlement decades earlier. Its seat, Springfield, had already been laid out in 1801 by James Demint, a former Kentucky teamster, and named for Springfield, Massachusetts; when the new county needed a courthouse town in 1818, Springfield beat the rival village of New Boston by only two votes. The county's Mad River valley had been Shawnee ground -- the large Pekowi and Kispoko town of Peckuwe stood a few miles from present Springfield until Clark burned it in August 1780 -- and the whole county passed to the United States under the Treaty of Greenville in 1795. Springfield went on to become "The Champion City," a nationally known center of farm-machinery manufacturing built around Warder, Bushnell & Glessner's Champion line (absorbed into International Harvester in 1902), while the National Road, reaching town in 1838, and Wittenberg University, founded in 1845, gave the county its other two defining institutions.
Springfield was founded in 1801 by James Demint, a former Kentucky teamster, who named it for Springfield, Massachusetts. When Clark County was organized in 1818 it needed a county seat, and Springfield was chosen over the rival village of New Boston by a margin of only two votes. The county's first courthouse, a two-story red brick building designed by Ambler & Fisher on the model of Ohio's original statehouse at Chillicothe, was pledged by subscription in 1819 but not completed until 1828; it was sold for $50 and demolished in 1878. A Second Empire-style replacement by Thomas J. Tolan & Son followed in 1878 and served until a fire on the morning of March 12, 1918 destroyed most of the building (court records were saved); architect William K. Schilling rebuilt it in Romanesque Revival style between 1918 and 1924 at a cost of $115,000, incorporating surviving exterior walls, and it remains the county's courthouse.

Almost every day here is a measurement: 96% of them come from a rain gauge standing inside Clark County itself.
47,921 days of records, 1893-01-01 to 2026-10-29. Source: NOAA NCEI GHCN-Daily, 3,240 gauges in and around Ohio. A day is "gauged" when a gauge standing inside the boundary reported it, and the value is the mean of those gauges. Otherwise it is interpolated by inverse distance from every gauge reporting within 50 miles. Nothing is carried forward, back-filled or smoothed. Against NOAA nClimDiv county monthly precipitation over 136,848 complete county-months (checked 2026-10-31): correlation 0.9515, median absolute difference 0.217 in a month. Built 2026-10-31 from the Cracked Buckeye precipitation archive. Snow is the softer number — snowfall is measured by hand with a ruler, no agency publishes a gridded county snowfall series, and blowing snow defeats every observer.
