Mercerville, NJ population, income and ZIP codes

Mercerville CDP is a mid-size town in New Jersey, with 13,693 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #96 of 700 ranked by population — larger than 86% of them. The median age here is 41.9 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Mercerville CDP earn a median of $125,678 a year, 60% above the national figure of $78,538 and 18% above 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 2.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Mercerville CDP is valued at $330,500, 8.9% above the national figure and 20% below the $412,500 peer median, while median gross rent runs $1,704 a month, 21.2% above the national figure, or roughly $20,448 across a full year. A household on the local median income would put about 16.3% 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 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 83.8% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
