Monthly gross rent of renter-occupied housing units paying cash rent, at the middle of the distribution, in US dollars of the last year of the period.

A median, not an average, of what all renters pay, including long-standing leases, so it is lower than asking rents for new listings. Medians outside the published range are coded 99 (under 100) or 3,501 (3,500 or more) and marked as estimated.
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.
