South Houston, TX population, income and ZIP codes

South Houston city is a mid-size town in Texas, with 16,017 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #196 of 1,863 ranked by population — larger than 89% of them. The median age here is 30.4 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 South Houston city earn a median of $52,611 a year, 33% below the national figure of $78,538 and 19% 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 23.5% 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 South Houston city is valued at $176,100, 42% below the national figure and within a couple of points of the $179,100 peer median, while median gross rent runs $1,174 a month, 16.5% below the national figure, or roughly $14,088 across a full year. A household on the local median income would put about 26.8% 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 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 54.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
