Somersworth city, NH in context

How this area compares with national benchmarks.

Somersworth city is a mid-size town in New Hampshire, with 12,060 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #13 of 100 ranked by population — larger than 87% of them. The median age here is 38.2 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 Somersworth city earn a median of $79,677 a year, 1.5% above the national figure of $78,538 and 3% above the $77,368 median for the 65 New Hampshire cities we cover. 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 11.4% of residents here, below the 12.4% national rate.

A household on the local median income would put about 21.2% 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 3.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 61.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters.
