20.3% of under-65 residents in Jefferson County were uninsured in 2024 — about 39,578 people — which is modestly above the Texas average of 19.1% and makes it the 105th highest of the 254 counties in Texas. Close enough to the state figure that the county is not an outlier; far enough that coverage gaps here are a real feature rather than a rounding artifact.

What you can actually buy here
6 insurers sell into Jefferson 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 91 plans, about 15 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.
29,547 marketplace plan selections were recorded in Jefferson County for 2026, or 152 per thousand under-65 residents — above the 127 typical of the counties covered here. Enough people locally have done this that the process is not unfamiliar territory. Only 3,826 were new consumers against 25,721 renewals — a 13% new share. A settled, returning population like that means the plans on offer have been chosen by the same people repeatedly, which is a reasonable signal that the networks hold up.
