Median gross rent

$1,623USD per month, ± $34

New Jersey $1,720, 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.

Houses and apartments

Type of homeAverage value, USD
All owner-occupied homes$476,877
Houses (one-unit, detached or attached)$489,967
Apartments (buildings with two or more units)$326,227
Mobile homes$66,952

2020–2024. This is an average, not a median, so a few very expensive homes pull it above the median home value. Values are each owner's own estimate of what the home would sell for, not sale prices. "Apartment" means an owner-occupied home in a building with two or more units, condominiums and co-ops included; rented homes are not counted. The Census Bureau publishes no median value for houses or for apartments (only for mobile homes), which is why this figure is an average. It publishes the underlying totals for the country, most states and about a quarter of counties; no figure is shown where an input is missing. It is not shown for census tracts, where the totals are rare and too unstable to read without a margin of error. Five-year pooled sample survey (2020–2024), not a single-year figure; small areas carry large margins of error.

Source: U.S. Census Bureau, American Community Survey 5-year estimates, 2020–2024. Calculated by Marsadata from ACS tables B25080 (total value of owner-occupied homes by units in structure) and B25032 (owner-occupied homes by units in structure): total value divided by the number of homes.

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.
