San Antonio, FL population, income and ZIP codes

San Antonio city is a small town in Florida, with 1,352 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #745 of 955 ranked by population — larger than 22% of them. The median age here is 41.8 years against 39.1 nationally, a slightly older 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 San Antonio city earn a median of $89,079 a year, 13.4% above the national figure of $78,538 and 30% 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 8.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in San Antonio city is valued at $357,400, 17.8% above the national figure and 17% above the $305,300 peer median, while median gross rent runs $1,000 a month, 28.9% below the national figure, or roughly $12,000 across a full year. A household on the local median income would put about 13.5% 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 4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 86.8% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
