ZIP code 03580

ZIP 03580 is a small town in Grafton County, New Hampshire, with 1,479 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #170 of 246 ranked by population — larger than 31% of them. The median age here is 56.5 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 03580 earn a median of $77,283 a year, 1.6% below the national figure of $78,538. 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 10.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 03580 is valued at $469,500, 54.7% above the national figure, while median gross rent runs $1,082 a month, 23% below the national figure, or roughly $12,984 across a full year. A household on the local median income would put about 16.8% 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 6.1×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 83.2% 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.

Home values sit at 6.1× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere. A median age of 56.5 puts ZIP 03580 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.

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.

ZIP 03580 is tabulated inside Grafton County, New Hampshire, one of 36 ZIP areas the Census publishes for that county and 246 across New Hampshire. Fewer than 2,500 people are counted here, so the ZIP behaves like a village delivery route rather than a neighbourhood. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 03580 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 03580 reports a median household income of $77,283, 5% below the $81,094 county median, and 17% below the $92,797 typical NH ZIP. Owner-occupied homes are valued at a median of $469,500, 65% above the county figure and 38% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,082 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 03580.

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. Five-year estimates pool sixty months of responses, so they are stable enough to compare 03580 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
