South River borough, NJ in context

How this area compares with national benchmarks.

South River borough is a mid-size town in New Jersey, with 16,007 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #73 of 700 ranked by population — larger than 89% of them. The median age here is 36.5 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 South River borough earn a median of $101,853 a year, 29.7% above the national figure of $78,538 and 5% 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. Poverty reaches 11.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in South River borough is valued at $382,500, 26.1% above the national figure and 7% below the $412,500 peer median, while median gross rent runs $1,599 a month, 13.7% above the national figure, or roughly $19,188 across a full year. A household on the local median income would put about 18.8% 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 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 65.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
