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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Most zip codes across Hawaii exhibit relatively low uninsured rates below 10%, with the darkest concentrations appearing throughout the Big Island's southern and western coasts and much of Oahu's urban core. A notable contrast exists on Kauai, where one zip code in the northwest displays a distinctly higher uninsured rate in the 15–20% range, standing out as a teal-shaded outlier against the predominantly dark purple tones statewide. The Big Island shows the greatest intra-island variation, with lighter-shaded areas along the northeastern Hamakua Coast and Kohala region suggesting moderately higher uninsured populations compared to the Hilo side.
