ZipCrawl

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the northern reaches of the metro—particularly in the Angeles National Forest foothills and parts of the San Gabriel Valley's eastern edge—register among the highest median ages, often exceeding 50, while a cluster of notably young zip codes (median age below 25) appears in southern Orange County near Irvine and the UC Irvine area, consistent with a large university-student population. Central Los Angeles neighborhoods from Downtown through Hollywood and south toward Inglewood generally fall in the 30–35 range, reflecting younger, denser urban populations, whereas coastal and suburban communities like Torrance, Huntington Beach, and much of the western San Fernando Valley trend older at 40–50. The sharpest contrast occurs between the deep blue/purple university-adjacent pockets in south Orange County and the immediately surrounding suburban zones that jump 15–20 years higher in median age within just a few zip codes.
