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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the northwestern corner of Oregon, particularly in the Portland metropolitan and Willamette Valley corridors, generally exhibit lower uninsured rates in the 0–10% range, while scattered rural zip codes across central, southern, and eastern Oregon display notably higher rates reaching 20–30% or more. Several isolated zip codes in south-central Oregon and near the eastern border show elevated uninsured concentrations of 25%+, with a small cluster near the Bend/Ontario areas approaching the upper end of the scale. The starkest contrast exists between the light gray and teal-shaded urban zones in the northwest and the deep purple and green pockets in sparsely populated southeastern and frontier regions, underscoring a persistent urban-rural insurance coverage divide.
