Glen Gardner, NJ population, income and ZIP codes

Glen Gardner borough is a small town in New Jersey, with 1,702 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #487 of 700 ranked by population — larger than 30% of them. The median age here is 42.2 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Glen Gardner borough earn a median of $98,750 a year, 25.7% above the national figure of $78,538 and 8% 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.

The typical owner-occupied home in Glen Gardner borough is valued at $280,000, 7.7% below the national figure and 32% below the $412,500 peer median, while median gross rent runs $1,472 a month, 4.7% above the national figure, or roughly $17,664 across a full year. A household on the local median income would put about 17.9% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 73.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

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.
