St. Augustine Shores, FL population, income and ZIP codes

St. Augustine Shores CDP is a mid-size town in Florida, with 9,921 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #348 of 955 ranked by population — larger than 63% of them. The median age here is 51.6 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 St. Augustine Shores CDP earn a median of $72,724 a year, 7.4% below the national figure of $78,538 and 6% 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 6.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in St. Augustine Shores CDP is valued at $290,000, 4.4% below the national figure and 5% below the $305,300 peer median, while median gross rent runs $1,746 a month, 24.2% above the national figure, or roughly $20,952 across a full year. A household on the local median income would put about 28.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 74.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 51.6 puts St. Augustine Shores 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.

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.
