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.
