2020–2024.

Gross rent is the contract rent plus utilities. It covers all renter households, sitting tenants included, so it lags the rents asked for new leases. Five-year pooled sample survey (2020–2024), not a single-year figure; small areas carry large margins of error. Medians above $3,500 are published only as "$3,500+" and medians below $100 as "$100-". Medians by number of bedrooms rest on fewer households, so they are missing more often and less precise.
