Penns Grove, NJ population, income and ZIP codes

Penns Grove borough is a small town in New Jersey, with 4,860 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #303 of 700 ranked by population — larger than 56% of them. The median age here is 26.1 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Penns Grove borough earn a median of $43,889 a year, 44.1% below the national figure of $78,538 and 59% below the $106,926 median for the 543 New Jersey cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 36.3% 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 Penns Grove borough is valued at $170,100, 43.9% below the national figure and 59% below the $412,500 peer median, while median gross rent runs $1,031 a month, 26.7% below the national figure, or roughly $12,372 across a full year. A household on the local median income would put about 28.2% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 38.2% 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.

A median age of 26.1 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
