ZipCrawl

NOTE: Gray indicates insufficient data or a suppressed estimate.

Median age skews youngest in Chicago's South Side neighborhoods around Englewood and in portions of the western suburbs near Aurora and Elgin, where several zip codes fall below 30, likely reflecting younger families and immigrant communities. The oldest-skewing zip codes cluster prominently in the far northern suburbs and along the northern lakefront exurbs, with pockets exceeding 55 years. A notable contrast exists between the consistently younger urban core—particularly The Loop and Near West Side—and the ring of older-median-age communities in the mid-range suburban belt stretching from Naperville through Schaumburg to Palatine.
