ZIP code 03101

ZIP 03101 is a small town in Hillsborough County, New Hampshire, with 3,148 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #115 of 246 ranked by population — larger than 53% of them. The median age here is 36.7 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 03101 earn a median of $80,483 a year, 2.5% above the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 21.9% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in ZIP 03101 is valued at $418,400, 37.9% above the national figure, while median gross rent runs $1,587 a month, 12.9% above the national figure, or roughly $19,044 across a full year. A household on the local median income would put about 23.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 5.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 6.1% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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 03101 is tabulated inside Hillsborough County, New Hampshire, one of 34 ZIP areas the Census publishes for that county and 246 across New Hampshire. Population sits in the small-town band, typically one main street plus the addresses that feed into it. 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 03101 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 03101 reports a median household income of $80,483, 21% below the $101,633 county median, and 13% below the $92,797 typical NH ZIP. Owner-occupied homes are valued at a median of $418,400, 13% above the county figure and 23% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,587 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 03101 carries 0% at the register, assembled from the Manchester jurisdiction stack: the New Hampshire state rate plus every county, municipal and special district levy that reaches this address. Because those district boundaries were drawn for schools, transit and hospital funding rather than for mail delivery, two addresses inside 03101 can legitimately fall under different totals — the rate shown here is the one that applies to the dominant jurisdiction.

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 03101 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.
