Marlborough, NH population, income and ZIP codes

Marlborough CDP is a very small community in New Hampshire, with 925 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #67 of 100 ranked by population — larger than 33% of them. The median age here is 50.3 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Marlborough CDP earn a median of $65,800 a year, 16.2% below the national figure of $78,538 and 15% below the $77,368 median for the 65 New Hampshire cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 9.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Marlborough CDP is valued at $241,800, 20.3% below the national figure and 11% below the $271,300 peer median, while median gross rent runs $1,004 a month, 28.6% below the national figure, or roughly $12,048 across a full year. A household on the local median income would put about 18.3% 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 3.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 49.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 50.3 puts Marlborough CDP well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 925 residents, a handful of survey responses moves every median on this page. Compare Marlborough CDP against its county rather than against national figures.

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.
