Population Non-Hispanic American Indian % by Zip Code (ZCTA5) — San Diego Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

The vast majority of zip codes across the San Diego metro area exhibit very low Non-Hispanic American Indian population shares, generally below 1-3%, as indicated by the uniformly dark purple shading spanning coastal and urban areas from Chula Vista through Encinitas. A notable exception appears in the northeastern interior, where one or two zip codes near the upper-right portion of the map display slightly elevated percentages, likely corresponding to tribal reservation lands in the backcountry east of Poway. The lighter-shaded zip code visible in the central-western portion of the map, near the coast, also stands out as a modest outlier against the otherwise consistently low regional baseline.
