Belfast, NY population, income and ZIP codes

Belfast CDP is a very small community in New York, with 648 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #972 of 1,292 ranked by population — larger than 24% of them. The median age here is 35.6 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 Belfast CDP earn a median of $51,250 a year, 34.7% below the national figure of $78,538 and 44% below the $91,806 median for the 847 New York cities we cover. 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 11.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Belfast CDP is valued at $85,700, 71.8% below the national figure and 73% below the $315,800 peer median, while median gross rent runs $505 a month, 64.1% below the national figure, or roughly $6,060 across a full year. A household on the local median income would put about 11.8% 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 1.7×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 69% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 648 residents, a handful of survey responses moves every median on this page. Compare Belfast CDP against its county rather than against national figures.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
