Middle Island, NY population, income and ZIP codes

Middle Island CDP is a mid-size town in New York, with 11,086 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #177 of 1,292 ranked by population — larger than 86% of them. The median age here is 43.4 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 Middle Island CDP earn a median of $89,702 a year, 14.2% above the national figure of $78,538 and within a couple of points of 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 12% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Middle Island CDP is valued at $347,900, 14.7% above the national figure and 10% above the $315,800 peer median, while median gross rent runs $1,774 a month, 26.2% above the national figure, or roughly $21,288 across a full year. A household on the local median income would put about 23.7% 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 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 66.7% 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
