About this ranking

People aged 35 to 64 without health insurance coverage of any kind, as a percentage of the civilian noninstitutionalized population aged 35 to 64. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.

Coverage is what people reported at the interview, so the five-year figure averages five years of answers. People whose only coverage is the Indian Health Service count as uninsured. Active-duty military and people living in institutions are outside the universe. For single-year model-based county figures under 65, see uninsured_rate_under_65, uninsured_rate_18_64 and uninsured_rate_under_19 (SAHIE), a different source.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
