Sinton, TX population, income and ZIP codes

Sinton city is a mid-size town in Texas, with 5,513 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #394 of 1,863 ranked by population — larger than 78% of them. The median age here is 31.9 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 Sinton city earn a median of $44,753 a year, 43% below the national figure of $78,538 and 31% 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 23.6% 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 Sinton city is valued at $109,300, 64% below the national figure and 39% below the $179,100 peer median, while median gross rent runs $831 a month, 40.9% below the national figure, or roughly $9,972 across a full year. A household on the local median income would put about 22.3% 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 2.4×, 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. 61% 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.

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.
