NOTE: Gray indicates insufficient data or a suppressed estimate.
Uninsured rates across North Carolina exhibit substantial geographic variation, with the highest concentrations (30–50%) clustered in the far western mountains—particularly a bright yellow zone near the Cherokee/Swain County area—and scattered pockets in rural central Piedmont and southeastern Coastal Plain zip codes. Metropolitan areas such as Charlotte, Raleigh-Durham, and the Research Triangle corridor generally display lower uninsured rates (under 10%), consistent with greater employer-sponsored coverage and healthcare access in urban centers. The gray-shaded zip codes lacking data are most prevalent along the Outer Banks and in sparsely populated rural areas, suggesting small population sizes that limit reliable estimation.
