About this ranking
Renter households whose gross rent (contract rent plus utilities and fuels the renter pays) was 30 percent or more of household income in the past 12 months, as a percentage of renter households for which that ratio can be computed. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.
Renters who pay no cash rent and households with no or negative income are left out of both the count and the base. 30 percent is the usual US threshold for rent burden. The EU housing cost overburden rate (housing_cost_overburden_rate) uses 40 percent of disposable income, all housing costs and people instead of households, so the two cannot be compared.
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.
