% of Population without Health Insurance, by Zip Code (ZCTA5) — Colorado

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the Denver metro area and along the Front Range corridor display considerable variation, with several urban zip codes reaching 25–35% uninsured rates—likely corresponding to areas with higher immigrant populations and lower employer-sponsored coverage—while adjacent suburban zip codes fall below 10%. The western slope and mountain resort communities generally show lower uninsured rates in the 5–15% range, contrasting with pockets of elevated uninsured populations in the San Luis Valley and parts of southeastern Colorado. A few isolated zip codes, particularly one near the central-western region and another along the eastern border, stand out with rates approaching or exceeding 40%, suggesting small populations with limited access to coverage options.
