San Antonio, TX population, income and ZIP codes

San Antonio city is a major city in Texas, with 1,458,954 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #2 of 1,863 ranked by population — larger than 99% of them. The median age here is 34.6 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in San Antonio city earn a median of $62,917 a year, 19.9% below the national figure of $78,538 and 3% 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 17.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in San Antonio city is valued at $219,700, 27.6% below the national figure and 23% above the $179,100 peer median, while median gross rent runs $1,258 a month, 10.5% below the national figure, or roughly $15,096 across a full year. A household on the local median income would put about 24% 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 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 52.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
