South Mountain, TX population, income and ZIP codes

South Mountain town is a very small community in Texas, with 295 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1447 of 1,863 ranked by population — larger than 22% of them. The median age here is 57.3 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 South Mountain town earn a median of $60,938 a year, 22.4% below the national figure of $78,538 and 6% below the $64,654 median for the 1,008 Texas cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 6.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in South Mountain town is valued at $170,800, 43.7% below the national figure and 5% below the $179,100 peer median, while median gross rent runs $988 a month, 29.7% below the national figure, or roughly $11,856 across a full year. A household on the local median income would put about 19.5% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 88.3% 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.

A median age of 57.3 puts South Mountain town well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 295 residents, a handful of survey responses moves every median on this page. Compare South Mountain town against its county rather than against national figures.

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.
