ZIP 03812 in context

How this area compares with national benchmarks.

ZIP 03812 is a very small community in Carroll County, New Hampshire, with 909 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #205 of 246 ranked by population — larger than 16% of them. The median age here is 57.7 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 ZIP 03812 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 4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 03812 is valued at $345,800, 14% above the national figure, while median gross rent runs not published a month. 92% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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 57.7 puts ZIP 03812 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 909 residents, a handful of survey responses moves every median on this page. Compare ZIP 03812 against its county rather than against national figures.

The Census withheld household income, gross rent for ZIP 03812 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.

Owner-occupied homes are valued at a median of $345,800, 4% below the county figure and close to the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published a month, which is why it reads higher than the advertised rent on a listing for the same unit.

New Hampshire charges 0% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 03812.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency.
