Why this happened
Lewisville, OH is Ohio's most remote inhabited place — but "remote" is relative here: just 25 miles from Marietta. Ohio is among the more densely populated US states; the average small-town resident lives 9 miles from a qualifying anchor. Lewisville's isolation is real to its 1,623 residents, even if the numbers are modest compared to Montana or Nevada.

More about Ohio
See the full breakdown of Ohio's counties at /states/ohio/counties — population, area, median income, and county seat for every county, plus a labeled printable map. The companion study 100-mile radius around Ohio's capital measures the share of Ohio's population that lives within day-trip distance of the capitol — an inverse framing of the isolation question this page poses.
Methodology (brief)
We aggregate the US Census ZCTA dataset by postal city, treating any (postal city, state) pair with ≥ 50 residents as a town. Anchor cities are places with ≥ 10,000 residents. For every Ohio town below the anchor threshold, we compute the straight-line distance to every anchor city in the US (cross-state distances count). The town with the largest minimum distance is Ohio's loneliest. Full methodology on the hub page.
