Underhill Flats, VT population, income and ZIP codes

Underhill Flats CDP is a very small community in Vermont, with 537 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #75 of 179 ranked by population — larger than 58% of them. The median age here is 42.5 years against 39.1 nationally, a slightly older 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 Underhill Flats CDP earn a median of $72,422 a year, 7.8% below the national figure of $78,538 and 10% above the $65,898 median for the 48 Vermont cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 3.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Underhill Flats CDP is valued at $275,300, 9.3% below the national figure and 12% above the $245,300 peer median, while median gross rent runs $951 a month, 32.4% below the national figure, or roughly $11,412 across a full year. A household on the local median income would put about 15.8% 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 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 65.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.
