% of Households with Broadband Internet, by Zip Code (ZCTA5) — San Antonio Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

Broadband adoption rates in the San Antonio metro exhibit a clear north-south divide, with zip codes in the northern suburbs and areas near New Braunfels generally exceeding 85–95% household coverage, while southern zip codes—particularly south of Von Ormy and in the far southern periphery—fall below 60–70%. The urban core around downtown San Antonio displays a patchwork pattern, with adjacent zip codes varying significantly, suggesting localized socioeconomic disparities influencing connectivity. Higher-income suburban developments to the northwest and northeast consistently cluster at the top of the scale, contrasting sharply with the deep teal shading across the largely rural southern and southwestern fringes of the metro.
