Household Median Income by Zip Code (ZCTA5) — San Antonio Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest median household incomes, exceeding $125,000, concentrate in the far northern zip codes stretching from the Hill Country northwest toward New Braunfels, forming a distinct affluence corridor along the I-35 and US-281 growth axes. Central San Antonio zip codes, particularly those immediately surrounding downtown, display the lowest incomes in the metro—falling below $30,000—creating a stark core-periphery gradient. The southern and southwestern portions of the metro generally remain in the $40,000–$60,000 range, with scattered pockets of higher income emerging in the southeast near recent suburban development.
