Stock Island, FL population, income and ZIP codes

Stock Island CDP is a small town in Florida, with 4,724 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #496 of 955 ranked by population — larger than 48% of them. The median age here is 35.2 years against 39.1 nationally, a slightly younger 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 Stock Island CDP earn a median of $67,005 a year, 14.7% below the national figure of $78,538 and within a couple of points of the $68,617 median for the 775 Florida cities we cover. 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 14.9% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Stock Island CDP is valued at $513,300, 69.2% above the national figure and 68% above the $305,300 peer median, while median gross rent runs $2,009 a month, 42.9% above the national figure, or roughly $24,108 across a full year. A household on the local median income would put about 36% 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 7.7×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 28% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

Home values sit at 7.7× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

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.
