The link opens the SimpleMapLab Map Radius Tool with a 50-mile circle drawn around Aragon. Try expanding the radius to see how far you have to look before encountering any 10,000+ city — the answer is roughly 86 miles in the direction of Whiteriver.
Why this happened
New Mexico's loneliest inhabited place is Aragon — 86 miles from Whiteriver in AZ.

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