Yaphank, NY population, income and ZIP codes

Yaphank CDP is a mid-size town in New York, with 6,140 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #311 of 1,292 ranked by population — larger than 75% of them. The median age here is 40 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 Yaphank CDP earn a median of $111,375 a year, 41.8% above the national figure of $78,538 and 21% above the $91,806 median for the 847 New York cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 5.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Yaphank CDP is valued at $421,100, 38.8% above the national figure and 33% above the $315,800 peer median, while median gross rent runs $2,831 a month, 101.4% above the national figure, or roughly $33,972 across a full year. A household on the local median income would put about 30.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. 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. 73.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Yaphank CDP is the unusual combination of expensive to rent and cheap to buy: rent takes 30.5% of median income while homes cost only 3.8× it. Where that pattern shows up, the gap is normally down to down-payment and credit barriers rather than price.
