Hawaii consistently ranks near the top of national healthcare scorecards because of a unique combination: a decades-old law that requires employers to insure workers, some of the lowest premiums and deductibles in the country, and a population that lives roughly four years longer than the national average. In the Commonwealth Fund’s 2025 State Health System Performance rankings, Hawaii placed second overall.
The Prepaid Health Care Act
The single biggest reason Hawaii outperforms other states is a law no other state has. The Prepaid Health Care Act, passed in 1974, requires nearly all private employers to provide health insurance to any employee who works at least 20 hours per week. Employers must cover at least half the premium cost, and the employee’s share is capped at 1.5% of their monthly gross earnings, whichever is less. That cap means low-wage workers aren’t priced out of coverage the way they often are on the mainland, where employee contributions can eat up a much larger share of a paycheck.
This mandate predates the Affordable Care Act by nearly four decades. Because it’s been in place so long, it shaped the entire insurance market in the state. Insurers compete within a framework where virtually every working adult is covered, which spreads risk broadly and keeps costs down for everyone. The result: Hawaii’s uninsured rate for working-age adults is just 3.9%, compared to 11% nationally.
Lower Premiums and Deductibles
Hawaii ranks first in the nation for health insurance affordability. The average annual employee premium for an employer-sponsored plan is about $1,060, the lowest of any state. For comparison, Vermont’s average is $2,145, Connecticut’s is $2,053, and the typical state falls somewhere between $1,600 and $1,800. Hawaii’s average individual deductible is $1,059 and its average family deductible is $2,683, both well below most states. In South Dakota, for instance, the average family deductible tops $5,000.
These lower out-of-pocket costs matter for everyday health decisions. When people aren’t worried about a surprise bill, they’re more likely to see a doctor for preventive care, catch problems early, and follow through on treatment. That dynamic shows up clearly in Hawaii’s health outcomes.
Longer Lives, Lower Death Rates
Hawaii residents live longer than people in any other state. Life expectancy was 82.1 years in 2019, about four years above the U.S. average, a gap that persisted even through the pandemic. While every state saw life expectancy drop during COVID-19, Hawaii’s decline was smaller (1.4 years, from 82.1 to 80.7 between 2019 and 2021), and the state recorded the lowest age-adjusted COVID-19 death rate in the country. By 2022, life expectancy had partially rebounded to 81.2 years.
Women in Hawaii live to about 84.4 on average, while men reach about 78.2. Both figures outpace their national counterparts by a significant margin. These numbers reflect not just good medical care but the lifestyle and environmental factors that make the state unusual.
Environment and Lifestyle Advantages
Hawaii’s climate allows year-round outdoor activity, and that shows up in population health data. About two-thirds of adults (66.6% as of 2023) live in neighborhoods with sidewalks, bike lanes, trails, or multi-use paths that support walking and cycling. The state also benefits from relatively clean air compared to heavily industrialized or high-traffic mainland metros. A culture that emphasizes fresh fish, rice, vegetables, and smaller portions compared to typical mainland diets plays a role too, though dietary patterns vary widely across the islands.
These environmental factors compound with the insurance picture. When people have both affordable healthcare access and a setting that encourages physical activity and clean air, each advantage reinforces the other.
Strong Primary Care Access
Hawaii has about 82 primary care physicians per 100,000 residents, compared to 76 per 100,000 nationally. No county in the state qualifies as severely underserved by the standard federal threshold of more than 2,000 people per primary care doctor. That baseline of primary care access means more residents have a regular doctor, get screened for chronic conditions, and manage issues like high blood pressure or diabetes before they become emergencies.
The Neighbor Island Gap
Hawaii’s strong statewide numbers mask a real disparity between Oahu, where most of the population and medical infrastructure sit, and the smaller neighbor islands. On islands like Kauai, Maui, and the Big Island, the physician shortage ranges from 30% to 43% compared to Oahu. Kauai residents have no on-island access to specialties like rheumatology, endocrinology, neonatology, pediatric cardiology, or pediatric oncology. For those conditions, patients must fly to Honolulu.
Specialty care in rural parts of the state is often described as sparse to nonexistent, with primary care doctors handling a wide range of conditions using limited resources. Housing shortages on the neighbor islands make it difficult to attract new physicians or even host medical trainees for clinical rotations. So while Hawaii’s system works exceptionally well in aggregate, the experience of someone living on Kauai or in a rural part of the Big Island can look very different from someone in urban Honolulu.
Why the Combination Matters
No single factor explains Hawaii’s healthcare performance. Other states have good weather. Others have high rates of insurance coverage. A few have strong primary care networks. What makes Hawaii unusual is that all of these factors exist simultaneously, anchored by a legal mandate that has been shaping the insurance market for over 50 years. The Prepaid Health Care Act created a foundation of near-universal coverage long before the rest of the country attempted anything similar, and the state built on that foundation with a population that benefits from geography, climate, and cultural norms around diet and activity.
That said, “best” comes with caveats. If you live on a neighbor island and need a specialist, your experience of Hawaii’s healthcare system may involve a flight, a hotel stay, and time away from work. The state’s rankings reflect averages, and averages always smooth over the people who fall outside them.
