Somerset County, NJ in context

How this area compares with national benchmarks.

Somerset County is a mid-size city in New Jersey, with 346,203 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 41.9 years against 39.1 nationally, a slightly older profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Somerset County earn a median of $135,960 a year, 73.1% above the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 5.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Somerset County is valued at $523,900, 72.7% above the national figure, while median gross rent runs $1,921 a month, 36.6% above the national figure, or roughly $23,052 across a full year. A household on the local median income would put about 17% 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 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 74.5% 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.

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.

How to read this page

What these estimates cover.

Figures are five-year rolling averages from the American Community Survey, not single-year counts, so they describe conditions across 2019-2023 ACS 5-year rather than a single date. Median home value covers owner-occupied units as valued by their owners, and median gross rent includes utilities the renter pays. Small counties carry wide margins of error; treat single-dollar differences between neighbouring counties as noise.
