Median Age by Zip Code (ZCTA5) — Missouri

NOTE: Gray indicates insufficient data or a suppressed estimate.

Missouri's median age distribution reveals a clear urban-youth pattern, with the Kansas City and St. Louis metropolitan areas, as well as Columbia (home to the University of Missouri), displaying notably lower median ages in the 20s–30s range compared to surrounding rural areas. The rural northern tier and Ozarks region in the south-central part of the state skew older, with numerous zip codes reaching median ages of 50–60, likely reflecting aging populations in areas experiencing long-term out-migration of younger residents. A striking concentration of very low median ages (deep purple, near 20) appears in the southeastern bootheel region and scattered college-town zip codes, contrasting sharply with the yellow-hued retirement and rural communities that dominate western and north-central Missouri.
