Seminole County is better covered than Florida as a whole: 11.3% of under-65 residents uninsured against a state average of 13.7%, or roughly 46,433 people. It is the 8th lowest of the 67 counties in Florida. Where employer coverage is this widespread, losing it tends to arrive as more of a shock — most people here have never bought their own plan.

What you can actually buy here
12 insurers sell into Seminole County — among the most competitive individual markets in the country. That much competition holds premiums down, and it produces a plan list long enough that choosing at random is a genuine risk. Narrowing by hospital system first is the only reliable way through it. Between them they offer 215 plans, about 18 for each insurer. A list that long is not more choice in any useful sense — it is the same handful of networks sliced into metal levels and deductible variants. The count is unchanged from last year, so the networks you compared previously still stand.
76,675 marketplace plan selections were recorded in Seminole County for 2026, or 187 per thousand under-65 residents — above the 127 typical of the counties covered here.

Roughly one in six enrollees here arrived within the year.
