Alamo Heights, TX population, income and ZIP codes

Alamo Heights city is a mid-size town in Texas, with 7,443 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #326 of 1,863 ranked by population — larger than 82% of them. The median age here is 40.6 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Alamo Heights city earn a median of $182,819 a year, 132.8% above the national figure of $78,538 and 183% above 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 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Alamo Heights city is valued at $766,000, 152.5% above the national figure and 328% above the $179,100 peer median, while median gross rent runs $1,426 a month, 1.4% above the national figure, or roughly $17,112 across a full year. A household on the local median income would put about 9.4% 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 4.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 72.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.
