Hamilton Square CDP, NJ in context
How this area compares with national benchmarks.
Hamilton Square CDP is a mid-size town in New Jersey, with 11,643 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #121 of 700 ranked by population — larger than 82% of them. The median age here is 46.2 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Hamilton Square CDP earn a median of $135,694 a year, 72.8% above the national figure of $78,538 and 27% 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 2.1% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in Hamilton Square CDP is valued at $376,900, 24.2% above the national figure and 9% below the $412,500 peer median, while median gross rent runs $1,817 a month, 29.2% above the national figure, or roughly $21,804 across a full year. A household on the local median income would put about 16.1% 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. 94.4% 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. 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.
