San Elizario, TX population, income and ZIP codes

San Elizario city is a mid-size town in Texas, with 10,123 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #267 of 1,863 ranked by population — larger than 85% of them. The median age here is 29 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Elizario city earn a median of $47,946 a year, 39% below the national figure of $78,538 and 26% below the $64,654 median for the 1,008 Texas cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 26.2% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in San Elizario city is valued at $106,500, 64.9% below the national figure and 41% below the $179,100 peer median, while median gross rent runs $874 a month, 37.8% below the national figure, or roughly $10,488 across a full year. A household on the local median income would put about 21.9% 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 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. 68.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

A median age of 29 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.
