Alton, NH population, income and ZIP codes

Alton CDP is a very small community in New Hampshire, with 416 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #81 of 100 ranked by population — larger than 19% of them. The median age here is 58.8 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 Alton CDP earn a median of not published a year. 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 2.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Alton CDP is valued at $358,200, 18.1% above the national figure and 32% above the $271,300 peer median, while median gross rent runs $623 a month, 55.7% below the national figure, or roughly $7,476 across a full year. 57% 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.

A median age of 58.8 puts Alton 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 416 residents, a handful of survey responses moves every median on this page. Compare Alton CDP against its county rather than against national figures.

The Census withheld household income for Alton CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
