Somerville borough, NJ in context

How this area compares with national benchmarks.

Somerville borough is a mid-size town in New Jersey, with 12,958 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #105 of 700 ranked by population — larger than 85% of them. The median age here is 35.5 years against 39.1 nationally, a slightly younger 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 Somerville borough earn a median of $103,869 a year, 32.3% above the national figure of $78,538 and 3% below 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 6.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Somerville borough is valued at $403,600, 33% above the national figure and within a couple of points of the $412,500 peer median, while median gross rent runs $1,748 a month, 24.3% above the national figure, or roughly $20,976 across a full year. A household on the local median income would put about 20.2% 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. 44.5% 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.

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.
