Comparatively few people go uncovered

4.4% of Santa Clara County's 1,595,535 under-65 residents have no health coverage — 69,724 people. That is below the California rate of 6.9%, and puts Santa Clara County in the bottom quarter of the 3,143 counties measured nationally (3,088th).

Relatively few are under the Medicaid line

15,134 of Santa Clara County's uninsured — 22%, below the 31% typical of counties nationally — earn under $22,025 a year, which in California is Medicaid territory rather than marketplace territory.
