West Babylon, NY population, income and ZIP codes

West Babylon CDP is a small city in New York, with 43,239 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #23 of 1,292 ranked by population — larger than 98% of them. The median age here is 40.8 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 West Babylon CDP earn a median of $127,785 a year, 62.7% above the national figure of $78,538 and 39% 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 5.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in West Babylon CDP is valued at $490,500, 61.7% above the national figure and 55% above the $315,800 peer median, while median gross rent runs $2,136 a month, 51.9% above the national figure, or roughly $25,632 across a full year. A household on the local median income would put about 20.1% 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 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 75.6% 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.
