Coverage is better here than across the state
7.6% of St. Johns County's 266,361 under-65 residents have no health coverage — 20,235 people. That is far below Florida as a whole, which sits at 13.7% — 6.1 points better than its own state, and puts St. Johns County in the bottom quarter of the 1,817 counties on this site (1460th).
