At 7.6% uninsured among under-65 residents — the lowest of the 67 counties in Florida — St. Johns County is among the best-covered parts of Florida, well below the state's 13.7%. Only about 20,235 people here have no coverage. That is good news with one edge to it: near-universal employer coverage means very little local familiarity with the individual market when a job ends.

What you can actually buy here
6 insurers sell into St. Johns County. At that number the market is competitive without being bewildering. Networks still differ sharply between carriers — more sharply than the monthly prices do — which is the opposite of how most people shop. Between them they offer 143 plans, about 24 for each insurer, which is a normal-sized list to work through once you know which network you need. The count is unchanged from last year, so the networks you compared previously still stand.
32,949 people here bought marketplace coverage for 2026, about 124 per thousand under-65 residents. That sits near the middle of the counties covered on this site: a working individual market, but most local coverage still arrives through an employer. 5,420 of them were new consumers and 27,529 were renewals — a 16% new share, close to the national pattern. Roughly one in six enrollees here arrived within the year.
