High School Graduate (% of Over 25) by Zip Code (ZCTA5) — San Diego Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

Coastal communities from Encinitas southward and inland areas near Poway and Santee consistently register high school graduation rates above 90%, appearing in bright yellow tones that indicate near-universal secondary education completion among adults over 25. A sharp contrast emerges in the urban core around National City and portions of San Diego's southern neighborhoods, where graduation rates drop below 60%, forming a distinct dark-shaded cluster amid otherwise higher-performing surrounding zip codes. The eastern rural and exurban zip codes display moderate graduation rates in the 75–85% range, creating a visible gradient between the high-performing coastal/suburban west and the mixed-outcome central and southern urban areas.
