Warren ZIP codes — Warren County, New Jersey

Warren County is a mid-size city in New Jersey, with 110,238 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 43.9 years against 39.1 nationally, a slightly older 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 Warren County earn a median of $99,596 a year, 26.8% above the national figure of $78,538. 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 8.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Warren County is valued at $323,100, 6.5% above the national figure, while median gross rent runs $1,368 a month, 2.7% below the national figure, or roughly $16,416 across a full year. A household on the local median income would put about 16.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 74.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
