Keystone, FL population, income and ZIP codes

Keystone CDP is a small city in Florida, with 26,723 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #158 of 955 ranked by population — larger than 83% of them. The median age here is 45.7 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 Keystone CDP earn a median of $155,365 a year, 97.8% above the national figure of $78,538 and 126% above the $68,617 median for the 775 Florida 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 4.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Keystone CDP is valued at $604,800, 99.3% above the national figure and 98% above the $305,300 peer median, while median gross rent runs $2,227 a month, 58.4% above the national figure, or roughly $26,724 across a full year. A household on the local median income would put about 17.2% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 91.1% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
