Nashua, NH population, income and ZIP codes

Nashua city is a small city in New Hampshire, with 91,131 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #2 of 100 ranked by population — larger than 98% of them. The median age here is 39.7 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 Nashua city earn a median of $92,457 a year, 17.7% above the national figure of $78,538 and 20% above the $77,368 median for the 65 New Hampshire 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 7.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Nashua city is valued at $373,100, 23% above the national figure and 38% above the $271,300 peer median, while median gross rent runs $1,652 a month, 17.5% above the national figure, or roughly $19,824 across a full year. A household on the local median income would put about 21.4% 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 4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 56.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

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.
