Trenton, NJ population, income and ZIP codes

Trenton city is a small city in New Jersey, with 89,966 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #6 of 700 ranked by population — larger than 99% of them. The median age here is 35.4 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Trenton city earn a median of $47,102 a year, 40% below the national figure of $78,538 and 56% below the $106,926 median for the 543 New Jersey cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 24.7% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Trenton city is valued at $122,500, 59.6% below the national figure and 70% below the $412,500 peer median, while median gross rent runs $1,224 a month, 12.9% below the national figure, or roughly $14,688 across a full year. A household on the local median income would put about 31.2% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 35.9% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Trenton city is the unusual combination of expensive to rent and cheap to buy: rent takes 31.2% of median income while homes cost only 2.6× it. Where that pattern shows up, the gap is normally down to down-payment and credit barriers rather than price.
