ZipCrawl

NOTE: Gray indicates insufficient data or a suppressed estimate.

Iowa's median age landscape reveals a pronounced pattern of younger populations concentrated in zip codes containing college towns and urban centers—notably the deep purple zones near Iowa City, Ames, and Cedar Falls, where median ages dip below 25—contrasted with the yellow-hued rural periphery along the western and southern borders where median ages frequently exceed 55. The northeastern corner of the state stands out as a particularly aging region, with a broad cluster of elevated median ages stretching along the Mississippi River bluffs. Much of central Iowa maintains a moderate median age in the 40–45 range, though scattered pockets of very low median ages likely correspond to smaller college communities or institutional populations embedded within otherwise older rural counties.
