About this ranking

Vacant housing units as a percentage of all housing units.

More on how it is measured
  • Vacant units include those for rent or for sale, rented or sold but not yet occupied, for seasonal, recreational or occasional use, for migrant workers, and other vacant units.
  • United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.

This gross rate counts seasonal and other off-market vacant units, so it is much higher than the rental and homeowner vacancy rates of the Housing Vacancy Survey (rental_vacancy_rate and homeowner_vacancy_rate) and cannot be compared with them. Counties with many holiday homes have high rates.

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.
