Zip codes in the Chicago suburban collar counties—particularly in DuPage, Lake, and McHenry counties—display the highest married-couple household rates, frequently exceeding 70%, while zip codes within the city of Chicago itself drop sharply to 20–30%, creating one of the starkest intra-regional contrasts on the map. Downstate urban centers such as Springfield, Champaign-Urbana, and the East St. Louis metro area also register notably lower percentages compared to their surrounding rural zip codes. Rural and small-town zip codes across central and southern Illinois generally cluster in the 50–60% range, with scattered pockets of higher rates in agricultural communities throughout the western and eastern portions of the state.
