Fisher Island, FL population, income and ZIP codes

Fisher Island CDP is a very small community in Florida, with 830 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #804 of 955 ranked by population — larger than 15% of them. The median age here is 55.5 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Fisher Island CDP earn a median of $250,001 a year, 218.3% above the national figure of $78,538 and 264% above the $68,617 median for the 775 Florida 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 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Fisher Island CDP is valued at $2,000,001, 559.2% above the national figure and 555% above the $305,300 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 8×, 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. 93.9% 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.

Home values sit at 8× 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. A median age of 55.5 puts Fisher Island CDP well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.

The Census withheld gross rent for Fisher Island CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
