Dover city, NH in context

How this area compares with national benchmarks.

Dover city is a small city in New Hampshire, with 33,070 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #4 of 100 ranked by population — larger than 96% of them. The median age here is 37.6 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 Dover city earn a median of $92,748 a year, 18.1% 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 8.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Dover city is valued at $398,500, 31.3% above the national figure and 47% above the $271,300 peer median, while median gross rent runs $1,540 a month, 9.5% above the national figure, or roughly $18,480 across a full year. A household on the local median income would put about 19.9% 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 4.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 51.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
