Somerville, MA population, income and ZIP codes

Somerville city is a small city in Massachusetts, with 80,549 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #13 of 248 ranked by population — larger than 95% of them. The median age here is 32.3 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Somerville city earn a median of $127,056 a year, 61.8% above the national figure of $78,538 and 28% 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 10.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Somerville city is valued at $899,400, 196.4% above the national figure and 81% above the $497,400 peer median, while median gross rent runs $2,468 a month, 75.5% above the national figure, or roughly $29,616 across a full year. A household on the local median income would put about 23.3% 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 7.1×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 34.3% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Home values sit at 7.1× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

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.
