Median Age by Zip Code (ZCTA5) — Mississippi

NOTE: Gray indicates insufficient data or a suppressed estimate.

Mississippi's youngest zip codes cluster around university towns and urban centers, with notably low median ages (under 25) visible near Starkville, Oxford, and Hattiesburg, reflecting large student populations. The Delta region along the western edge and rural areas in the southern interior tend toward higher median ages, frequently exceeding 45–50, suggesting aging populations in economically challenged areas experiencing youth out-migration. A broad band of moderate-to-high median ages (40–50) characterizes much of the central and northern portions of the state, punctuated by pockets of younger populations around Jackson and the Gulf Coast metropolitan areas.
