Islandia village, NY in context

How this area compares with national benchmarks.

Islandia village is a small town in New York, with 3,581 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #446 of 1,292 ranked by population — larger than 65% of them. The median age here is 39.1 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 Islandia village earn a median of $112,435 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. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 3.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Islandia village is valued at $451,700, 48.9% above the national figure and 43% above the $315,800 peer median, while median gross rent runs $1,781 a month, 26.7% above the national figure, or roughly $21,372 across a full year. A household on the local median income would put about 19% 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 4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 96.3% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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.
