Median Age by Zip Code (ZCTA5) — Denver Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

Younger median ages cluster in the northeastern portions of the metro area near Thornton and into the far northeast Aurora zip codes, where values dip into the low-to-mid 30s, likely reflecting newer suburban development attracting younger families. In contrast, the western and southwestern zip codes—including parts of Lakewood and the foothills communities—trend notably older, with median ages reaching into the mid-40s and above. A small pocket south of Denver near Centennial stands out with an exceptionally high median age approaching 60, while a bright yellow outlier in the south-central area suggests a similarly aged enclave, potentially associated with a retirement community or age-restricted housing.
