San Leon, TX population, income and ZIP codes

San Leon CDP is a mid-size town in Texas, with 5,764 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #385 of 1,863 ranked by population — larger than 79% of them. The median age here is 45.1 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 San Leon CDP earn a median of $76,573 a year, 2.5% below the national figure of $78,538 and 18% above the $64,654 median for the 1,008 Texas 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 8.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in San Leon CDP is valued at $166,700, 45.1% below the national figure and 7% below the $179,100 peer median, while median gross rent runs $1,152 a month, 18.1% below the national figure, or roughly $13,824 across a full year. A household on the local median income would put about 18.1% 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 2.2×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 82.2% 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.
