27.8%, Explained: The Map Is the Story
Chicago is 27.8% Black. That number is true — and by itself, it misleads.
The Census Bureau counts 2,719,960 people in Chicago, and 755,738 of them are Black — 27.8% of the city (American Community Survey 2024 5-Year, Table B02001, across 791 census tracts).
Now look at the map.
The median Chicago tract is only 10.2% Black — less than half the citywide share. 191 tracts are 75% Black or more, home to 460,048 Black Chicagoans. 76.6% of Black Chicago — 579,160 people — lives in tracts that are at least half Black. And 293 tracts are under 5% Black.
Two Chicagos share one average. The map, not the mean, is the honest picture.
Every figure here was recomputed from the tract file itself — not copied from a summary — and reconciled two independent ways before publication. Population is a signal, never a verdict.
In plain words
About 28 of every 100 Chicagoans are Black. But Black Chicago is not spread evenly — most Black Chicagoans live in neighborhoods that are mostly Black, and many neighborhoods have almost no Black residents. The map shows what the single number hides.
