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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in and around central Denver and the Aurora corridor exhibit the highest uninsured rates in the metro area, with several zones reaching 15–25%, likely reflecting concentrations of lower-income and immigrant communities. The outer suburban and exurban periphery—particularly to the south toward Centennial and the far northeast—trends noticeably lower, generally falling below 5–10%. Broomfield and western Arvada appear as pockets of relatively low uninsured rates, contrasting sharply with the elevated levels in the adjacent Thornton and north Denver zip codes just to the east.
