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

NOTE: Gray indicates insufficient data or a suppressed estimate.

High school graduation rates across the San Francisco metro area exhibit stark geographic disparities, with outer suburban and exurban zones—particularly in eastern Contra Costa County, the Tri-Valley, and much of southern Santa Clara County—reaching 95–100%, while concentrated pockets of lower attainment (below 70%) cluster in parts of central Oakland, East San Jose, and sections of Richmond. The peninsula communities between Daly City and San Jose display a mixed pattern, with coastal and hillside zip codes generally outperforming those along the bayshore corridor. This urban-core-to-suburban gradient is disrupted notably by several deep-teal zip codes in downtown San Jose, suggesting localized concentrations of residents without high school credentials amid otherwise high-attainment surroundings.
