South Hill, NY population, income and ZIP codes

South Hill CDP is a mid-size town in New York, with 6,805 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #284 of 1,292 ranked by population — larger than 78% of them. The median age here is 20.1 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in South Hill CDP earn a median of $112,437 a year, 43.2% above the national figure of $78,538 and 22% above the $91,806 median for the 847 New York cities we cover. 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 14.7% of residents here, above the 12.4% national rate.

The typical owner-occupied home in South Hill CDP is valued at $335,100, 10.4% above the national figure and 6% above the $315,800 peer median, while median gross rent runs $1,647 a month, 17.1% above the national figure, or roughly $19,764 across a full year. A household on the local median income would put about 17.6% 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×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 62.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

A median age of 20.1 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. 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.

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.
