States Ranked by Health Care Outcomes

Three rulers, one picture

Health system rankings can be gamed by choosing flattering inputs. This one uses three that are hard to argue with: an independent 50-indicator scorecard, a death record, and an insurance count. The Commonwealth Fund's 2025 Scorecard put Massachusetts, Hawaii, New Hampshire, and Rhode Island at the top among states, with the District of Columbia also in the leading group, and put Mississippi, Texas, Oklahoma, Arkansas, and West Virginia at the bottom (Commonwealth Fund, 2025). CDC data put national life expectancy at 78.4 years in 2023, recovering from the pandemic but still below the 2019 level. The Census Bureau put the national uninsured rate at 7.9 percent in 2023.

All three rulers point the same direction. The states at the top of the scorecard also live longest and are insured at the highest rates. The states at the bottom die youngest and are uninsured at the highest rates. When independent measures converge like that, the ranking is not an artifact of method.

A seven-year gap in life itself

Hawaii's life expectancy of roughly 81 years and Mississippi's of just under 74 differ by about seven years (CDC NCHS, 2023). That is the single most important number in this report. It is not a difference in hospital amenities or wait times. It is a difference in how long residents are alive.

The geography is stark. Every state in this ranking's bottom ten is in the South. Every state in the top six is in the Northeast or Pacific. The drivers documented in the federal data include smoking, obesity, overdose, and cardiovascular death rates, along with insurance coverage and access to primary care. The scoreboard does not assign blame between behavior and policy. It records the result.

Coverage is the clearest policy fingerprint in the data

The uninsured numbers split along one policy line more than any other. States that expanded Medicaid under the Affordable Care Act had a combined uninsured rate of 6.4 percent in 2023; non-expansion states sat at 11.3 percent (Census Bureau, ACS 2023). Texas, the largest non-expansion state, has the highest uninsured rate in the nation at 16.4 percent overall and 23 percent among working-age adults (Census ACS, 2023; Commonwealth Fund, 2025). Massachusetts, which built the model the ACA copied, has the lowest at about 2.4 percent.

Honesty requires the counterexample: coverage alone does not buy longevity. Kentucky, West Virginia, and Louisiana all expanded Medicaid and all sit near the bottom on life expectancy. Insurance is measurable and policy-controlled; the diseases that shorten lives in the lowest-ranked states accumulated over decades. Both facts are in the record, and this composite weights outcomes, not intentions.

What the top states have in common, and what they do not

The top of this table is politically mixed at the margins but structurally consistent: near-universal coverage, low avoidable hospital use, and low premature mortality. Massachusetts leads on nearly every access measure the Commonwealth Fund tracks (Mass.gov, 2025). Hawaii pairs high coverage with the longest lives (Hawaii DOH, 2025). Utah cracks the top 15 largely on healthy-lives measures, with among the lowest smoking rates in the country, showing there is more than one route into the upper tier.

The 2025 Scorecard's authors added a warning worth recording: the coverage gains that drove recent improvement are, in their words, at risk, as pandemic-era subsidies and Medicaid provisions unwind (Commonwealth Fund, 2025). If those reversals materialize, the next edition of this table will show it, and this report will print it either way.
