Locust Valley CDP, NY in context

How this area compares with national benchmarks.

Locust Valley CDP is a small town in New York, with 3,591 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #445 of 1,292 ranked by population — larger than 65% of them. The median age here is 42.6 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 Locust Valley CDP earn a median of $137,344 a year, 74.9% above the national figure of $78,538 and 50% above 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 4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Locust Valley CDP is valued at $775,200, 155.5% above the national figure and 145% above the $315,800 peer median, while median gross rent runs $2,274 a month, 61.7% above the national figure, or roughly $27,288 across a full year. A household on the local median income would put about 19.9% 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 5.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 75.1% 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.
