More about Washington
See the full breakdown of Washington's counties at /states/washington/counties — population, area, median income, and county seat for every county, plus a labeled printable map. The companion study 100-mile radius around Washington's capital measures the share of Washington'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 Washington 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 Washington's loneliest. Full methodology on the hub page.
