San Juan city, TX population, income and ZIP codes

San Juan city is a small city in Texas, with 35,674 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #100 of 1,863 ranked by population — larger than 94% of them. The median age here is 29.7 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 Juan city earn a median of $53,440 a year, 32% below the national figure of $78,538 and 17% below 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 24.5% 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 Juan city is valued at $118,200, 61% below the national figure and 34% below the $179,100 peer median, while median gross rent runs $937 a month, 33.4% below the national figure, or roughly $11,244 across a full year. A household on the local median income would put about 21% 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. 79.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 29.7 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.
