Somerset, MA population, income and ZIP codes

Somerset CDP is a mid-size town in Massachusetts, with 18,246 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #72 of 248 ranked by population — larger than 71% of them. The median age here is 47 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 Somerset CDP earn a median of $111,720 a year, 42.2% above the national figure of $78,538 and 12% above the $99,537 median for the 222 Massachusetts cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Somerset CDP is valued at $389,400, 28.3% above the national figure and 22% below the $497,400 peer median, while median gross rent runs $1,313 a month, 6.6% below the national figure, or roughly $15,756 across a full year. A household on the local median income would put about 14.1% 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 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 84.4% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
