About this ranking

All housing units, occupied and vacant: houses, apartments, mobile homes and rooms intended as separate living quarters. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.

A survey estimate averaged over five years, not a count on one date.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
