Median gross rent

$1,090USD per month, ± $22

Illinois $1,274, U.S. $1,413

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.

Hourly figure calculated by Marsadata: the weekly wage divided by 40 hours. The source does not report hours worked and counts part-time jobs, so actual hourly pay is higher where part-time work is common.

Monthly figure calculated by Marsadata: the weekly wage times 52, divided by 12.

Covers jobs at employers subject to unemployment insurance, more than 95% of U.S. jobs; the self-employed are not included. Wages include bonuses. It is an average per job, full-time and part-time alike, not per worker. Figures are withheld where they could reveal an individual employer. Recent figures are revised by the publisher.
