Marlboro, NY population, income and ZIP codes

Marlboro CDP is a small town in New York, with 3,959 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #417 of 1,292 ranked by population — larger than 67% of them. The median age here is 44.1 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 Marlboro CDP earn a median of $116,549 a year, 48.4% above the national figure of $78,538 and 27% 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 3.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Marlboro CDP is valued at $352,200, 16.1% above the national figure and 12% above the $315,800 peer median, while median gross rent runs $1,666 a month, 18.5% above the national figure, or roughly $19,992 across a full year. A household on the local median income would put about 17.2% 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. 77.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
