Suffolk ZIP codes — Suffolk County, New York

Suffolk County is a major city in New York, with 1,525,680 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 41.7 years against 39.1 nationally, a slightly older profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Suffolk County earn a median of $128,329 a year, 63.4% above the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 6.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Suffolk County is valued at $539,500, 77.8% above the national figure, while median gross rent runs $2,190 a month, 55.8% above the national figure, or roughly $26,280 across a full year. A household on the local median income would put about 20.5% 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 4.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 81.9% 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.

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.
