Rio Grande City, TX population, income and ZIP codes

Rio Grande City city is a mid-size town in Texas, with 15,258 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #206 of 1,863 ranked by population — larger than 88% of them. The median age here is 28.5 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 Rio Grande City city earn a median of $41,369 a year, 47.3% below the national figure of $78,538 and 36% below the $64,654 median for the 1,008 Texas cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 33.9% 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 Rio Grande City city is valued at $113,400, 62.6% below the national figure and 37% below the $179,100 peer median, while median gross rent runs $742 a month, 47.2% below the national figure, or roughly $8,904 across a full year. A household on the local median income would put about 21.5% 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 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 69.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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 28.5 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.
