Blackwells Mills, NJ population, income and ZIP codes

Blackwells Mills CDP is a mid-size town in New Jersey, with 10,220 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #148 of 700 ranked by population — larger than 78% of them. The median age here is 40.6 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 Blackwells Mills CDP earn a median of $248,149 a year, 216% above the national figure of $78,538 and 132% above the $106,926 median for the 543 New Jersey cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 1.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Blackwells Mills CDP is valued at $736,000, 142.6% above the national figure and 78% above the $412,500 peer median, while median gross rent runs $3,148 a month, 123.9% above the national figure, or roughly $37,776 across a full year. A household on the local median income would put about 15.2% 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×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 96.4% 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.

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.
