About this ranking

Number of households, which equals the number of occupied housing units. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.

People living in group quarters, such as college dormitories, nursing homes and prisons, are not in households.

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.
