Setauket CDP, NY in context

How this area compares with national benchmarks.

Setauket CDP is a small town in New York, with 3,687 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #435 of 1,292 ranked by population — larger than 66% of them. The median age here is 43.1 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 Setauket CDP earn a median of $202,339 a year, 157.6% above the national figure of $78,538 and 120% 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 6.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Setauket CDP is valued at $708,100, 133.4% above the national figure and 124% above the $315,800 peer median, while median gross rent runs $3,501 a month, 149% above the national figure, or roughly $42,012 across a full year. A household on the local median income would put about 20.8% 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 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 77.9% 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.

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.
