Median Age by Zip Code (ZCTA5) — Tennessee

NOTE: Gray indicates insufficient data or a suppressed estimate.

Tennessee's median age distribution reveals a pronounced urban-youth corridor, with the lowest values (dark blue-purple, under 25) concentrated around Chattanooga and notably in areas likely corresponding to college towns like Murfreesboro and Sewanee. The western third of the state, particularly the Memphis metropolitan area, skews younger overall compared to the eastern plateau and ridge regions, where scattered zip codes in the Cumberland Plateau and upper East Tennessee push median ages above 55. A notable band of higher median ages (yellow, 55–60+) appears across several rural zip codes in the central-south and eastern portions of the state, contrasting sharply with the younger suburban growth corridors ringing Nashville.
