ZIP Code 11971

Households in the Stony Brook area's 11971 ZIP code earn a median of $129,507, with per-capita income at $76,891 — figures that place this community firmly in affluent territory. Home values reinforce that standing: the median property is worth $843,300, and the county-level effective property tax rate of 1.73% means owners shoulder a substantial annual bill on that valuation. Add an 8.75% combined sales tax on purchases, and the overall cost of living here runs high. This is a prosperous enclave where strong incomes are matched by steep housing prices and a tax load to go with them.
