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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Non-Hispanic American Indian population across the Chicago metro area is remarkably low and uniformly distributed, with virtually all zip codes registering below 1%, as indicated by the deep purple shading that dominates the entire region. A small cluster of zip codes along the southeastern lakefront near the Illinois-Indiana border displays slightly elevated percentages in the 3–5% range, representing the only notable deviation from the otherwise homogeneous pattern. No significant urban-suburban or core-periphery gradient is evident, distinguishing this demographic measure from most other racial/ethnic distribution maps of the metro area.
