Median Age by Zip Code (ZCTA5) — San Diego Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

Coastal communities near Encinitas and the northern shoreline exhibit notably higher median ages, with several zip codes reaching into the mid-50s to low 60s, reflecting established retirement and affluent residential enclaves. In sharp contrast, central San Diego neighborhoods—particularly around the university areas and mid-city—display some of the lowest median ages in the metro, dipping below 30, likely driven by student populations and younger renter demographics. The eastern suburbs including Santee, El Cajon, and Chula Vista cluster in the mid-30s to low 40s range, representing a moderate demographic middle ground between the aging coastal north and the younger urban core.
