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

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Chicago metro area exhibits stark racial segregation, with Non-Hispanic White population percentages dropping below 10% in a concentrated corridor stretching from the South and West sides of Chicago through Gary, Indiana, while the far northern and western suburban fringe—particularly areas northwest of Palatine and southwest toward Joliet—consistently exceeds 70-80%. A notable transition zone runs through the inner-ring suburbs like Cicero and areas near O'Hare, where percentages fall in the 30-50% range, reflecting more diverse or mixed-composition communities. The sharpest contrasts occur along the boundary between Englewood and the southwestern suburbs, where adjacent zip codes can differ by 50 or more percentage points.
