Household Median Income by Zip Code (ZCTA5) — Austin Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest household median incomes, exceeding $125,000, concentrate in the northwestern and western zip codes stretching from Cedar Park through Georgetown, forming a pronounced affluence corridor along the I-35/US-183 growth axis. A sharp income gradient emerges near downtown Austin, where a small cluster of zip codes dips below $30,000—likely corresponding to the university and East Riverside areas—contrasting starkly with adjacent western zip codes reporting incomes two to four times higher. Suburban communities to the east and northeast, including Pflugerville and portions of Round Rock, occupy a middle band roughly between $60,000 and $90,000, reflecting the more moderate-income suburban development patterns on that side of the metro.
