Key West, FL population, income and ZIP codes

Key West city is a small city in Florida, with 25,824 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #163 of 955 ranked by population — larger than 83% of them. The median age here is 46.5 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Key West city earn a median of $78,532 a year, essentially level with the national figure of $78,538 and 14% 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 11.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Key West city is valued at $816,300, 169.1% above the national figure and 167% above the $305,300 peer median, while median gross rent runs $2,075 a month, 47.6% above the national figure, or roughly $24,900 across a full year. A household on the local median income would put about 31.7% 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 10.4×, 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. 47.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 10.4× 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.
