Businesses opening and closing

How many workplaces with employees opened and closed each year since 1978, how many people applied to start a business, and how many businesses run with no employees at all.

workplaces opened in 2023: 183; 146 closed

net workplaces, 2019 to 2023: +69; openings minus closings

applications to start a business, 2025: 1,179; +105% since 2019

businesses with no employees, 2023: 7,801; +20% since 2012

A workplace here is one location with paid employees: a chain with five stores is five. An application to start a business is a request for a federal employer number, not an opening, and most applicants never hire anyone.

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: 1; 1 in the worst tenth of the 88

of the 85 counties with anything flagged: 80th worst; environment

"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 Miami County began

Miami County, Ohio was organized in 1807 from Montgomery County, taking its name from the Miami people who lived and traded along the Great Miami River that runs the length of the county. Troy was platted the same year as the new county seat. The county's land had been Shawnee and Miami territory until the 1795 Treaty of Greenville, and it holds the site of Pickawillany, a Miami trading town destroyed in 1752 in one of the opening episodes of the contest between Britain and France for the Ohio Country. Miami County grew through the Miami and Erie Canal era of the 1830s-1840s, then into a manufacturing and agricultural county whose largest cities, Troy and Piqua, still anchor it today.

Troy was platted around 1807, the year Miami County was organized, and is the county seat.

88% of these days are measurements from a gauge inside Miami County; the rest are estimated from the nearest gauges around it.

48,463 days of records, 1893-06-02 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.
