States With the Highest Uninsured Rates: Health Insurance Access Map

Texas has roughly 17% of its population uninsured, nearly double the national rate of around 8-9%. Where you live determines whether health coverage is a baseline expectation or a daily gamble.

The States With the Worst Coverage

The five states with the highest uninsured rates share a clear pattern: they are largely in the South and West, and most declined to expand Medicaid under the Affordable Care Act for years. As of the most recent available state-level data (late 2025), the bottom five look like this:

• Texas: ~16.7-17% uninsured
• Oklahoma: ~14-15% uninsured
• Florida: ~13-14% uninsured
• Georgia: ~13% uninsured
• Wyoming: ~12-13% uninsured

Texas stands alone at the top. The state has never expanded Medicaid, leaving an estimated 1 million residents in a coverage gap, earning too much for traditional Medicaid but too little to qualify for marketplace subsidies. Oklahoma expanded Medicaid in 2021, but its uninsured rate has been slow to fall. Florida, despite being one of the most populous states in the country, still has not expanded Medicaid as of mid-2026, leaving roughly 3 million residents without coverage.

Where Coverage Is Near-Universal

Massachusetts consistently posts the lowest uninsured rate in the country, around 2.8-3.3%. The state built a universal coverage framework before the ACA existed, and that infrastructure still pays off today. Other low-uninsured states include:

• Hawaii: ~4-5% uninsured, partly due to a 1974 employer mandate law
• Minnesota: ~5% uninsured
• Vermont: ~5-6% uninsured
• Wisconsin: ~6% uninsured

Every state on this list either expanded Medicaid, has its own strong coverage mandates, or both. The correlation is not subtle.

Why the Gaps Are So Large

The Medicaid expansion divide explains most of the difference between states. States that expanded Medicaid under the ACA gave coverage to adults earning up to 138% of the federal poverty level. States that did not created a gap where low-income adults fall through entirely.

As of mid-2026, ten states have still not fully embraced expansion or have partial programs with significant restrictions. Texas, Florida, and Georgia are the biggest holdouts by population, which is exactly why they dominate the bottom of every uninsured ranking.

The national uninsured rate sat at roughly 8-9% as of late 2025, down sharply from 15-16% before ACA implementation in 2014. The gains have been real, but they have not been evenly distributed. The gap between Massachusetts at 3% and Texas at 17% is wider than the gap between the U.S. average and many peer nations.

Cost is the second driver. Even in states with marketplace options, monthly premiums and deductibles push coverage out of reach for workers who do not get employer-sponsored insurance. A 35-year-old in a high-uninsured state might face a benchmark silver plan premium of $400-500 per month after subsidies run out, which is a non-starter for someone earning $35,000 a year.

What This Means If You're Choosing Where to Live

Health insurance access is a real cost-of-living variable. A state with no income tax looks appealing on paper, but if you are self-employed, a gig worker, or between jobs, that same state may offer you thin coverage options, high premiums, and a stripped-down Medicaid program.

Texas has no state income tax, which is a genuine financial advantage we cover in Texas vs. New York: What You Actually Keep. But for someone whose employer does not offer coverage, Texas is one of the hardest places in the country to get affordable insurance. That tradeoff is worth pricing out explicitly.

For retirees, the calculus is slightly different. Medicare eligibility at 65 removes the individual market problem, but pre-Medicare years from 60 to 64 can be brutal in low-expansion states. If you are planning an early retirement, a state's Medicaid generosity and marketplace depth matter more than most retirement guides admit. Our post on Best States for Retirees to Avoid Taxes covers tax angles, but factor coverage access into the same decision.

Key Takeaways

• Texas has the highest uninsured rate in the country at approximately 16.7-17%, roughly twice the national average of 8-9%.
• The five worst states for coverage, Texas, Oklahoma, Florida, Georgia, and Wyoming, all have limited or no Medicaid expansion, and that single policy choice explains most of the gap.
• Massachusetts holds the lowest uninsured rate at approximately 2.8-3.3%, a direct result of its pre-ACA universal coverage architecture.
