The World Health Organization ranked the healthcare systems of 191 countries exactly once, in its World Health Report 2000. France came in first, Italy second, and the United States placed 37th. That single report became one of the most cited and most contested pieces of health policy research ever published, and the WHO has never released a comparable ranking since.
What the 2000 Report Actually Measured
The WHO evaluated health systems on three broad goals: how much they improved population health, how well they responded to people’s expectations (things like dignity, autonomy, and prompt attention), and how fairly they distributed the financial burden of healthcare. Both the overall level and the equity of each goal mattered. A country where wealthy residents received excellent care but the poor went without would score lower than one where quality was more evenly distributed.
The report produced two separate league tables that are often confused. One measured overall health attainment, where Japan ranked first and Switzerland second, reflecting those countries’ high life expectancy and low disease burden. The other, more famous ranking measured health system performance: how effectively a country translated its resources into results. On that measure, France and Italy topped the list, while the United States fell to 37th, sandwiched between Costa Rica and Slovenia, despite spending far more per person than any other nation.
Why the WHO Never Ranked Again
The backlash was swift and intense. Critics pointed out that the data underlying the rankings were thin. For many countries, reliable health statistics simply didn’t exist, and the WHO filled the gaps by extrapolating from other nations’ numbers. Some measures relied on value judgments drawn from small, unrepresentative surveys. Brazil protested furiously over its placement. One health economist dismissed the entire approach as “marketing” rather than science.
By the following year, the WHO’s executive board instructed then-Director General Gro Harlem Brundtland to consult more widely on how to measure performance before publishing another edition. That consultation led to delays, and the revised ranking never materialized. Some observers noted that shelving a politically explosive report was convenient timing for Brundtland, whose term was ending and whose renomination process was approaching. Whatever the mix of scientific and political reasons, the WHO shifted to tracking specific indicators rather than producing a single composite score, and it has stayed on that path for over two decades.
What the WHO Tracks Now
Instead of ranking countries against each other, the WHO now monitors Universal Health Coverage (UHC) through a service coverage index. This score, ranging from 0 to 100, measures whether people can actually access essential health services including reproductive care, infectious disease treatment, chronic disease management, and hospital capacity.
The global average UHC index rose from 54 in 2000 to 71 in 2023, a meaningful improvement but one that masks enormous variation. The highest-scoring countries reach 92, while the lowest sit at 26. The WHO also tracks Healthy Life Expectancy (HALE), which measures how many years a person can expect to live in full health rather than simply alive. As of 2021, Singapore leads at 73.6 years, followed closely by Japan at 73.4, South Korea at 72.5, and Iceland at 71.4.
How Other Organizations Compare Countries
The void left by the WHO’s single ranking has been filled by several recurring reports, each measuring something slightly different.
The Commonwealth Fund publishes its “Mirror, Mirror” series comparing healthcare in ten high-income countries across domains like access, equity, and outcomes. The OECD releases “Health at a Glance” annually, offering granular data on spending, wait times, and access across its member nations. These reports don’t reduce everything to a single number the way the WHO did, which makes them less quotable but arguably more useful.
OECD data illustrates the tradeoffs well. Member countries spent an average of 9.2% of GDP on healthcare in 2022, down from a pandemic peak of 9.7% in 2021 but still higher than the pre-pandemic average of 8.8%. Household out-of-pocket payments account for nearly a fifth of health spending on average, and in some countries exceed 40%. People in the lowest income bracket are three times more likely to delay or skip care than those in the highest. Wait times for common procedures like hip and knee replacements have improved since the worst pandemic disruptions but remain longer than pre-2020 levels in most countries.
Why a Single Ranking Is So Difficult
The core problem the WHO ran into hasn’t gone away. Any composite ranking requires deciding how much weight to give competing priorities. Is a system that delivers longer life expectancy but with high out-of-pocket costs better or worse than one with shorter lifespans but free access? Should responsiveness, essentially patient experience, count as much as measurable health outcomes? The 2000 report made specific choices about these tradeoffs, and reasonable people disagreed sharply with those choices.
Data quality remains a challenge too. Wealthier nations collect detailed health statistics through electronic records and population registries. Many lower-income countries still lack the infrastructure to reliably track outcomes, meaning any global ranking inevitably compares hard data from some nations against estimates for others. The WHO’s shift toward tracking individual indicators like UHC coverage and healthy life expectancy sidesteps this problem by letting each metric stand on its own rather than folding uncertain numbers into a single score.
What the Rankings Can and Can’t Tell You
If you’re trying to understand which countries have the best healthcare, the honest answer is that it depends on what you mean by “best.” France’s top placement in 2000 reflected strong performance across multiple dimensions, particularly financial fairness, since the French system shields patients from catastrophic costs. Japan and Singapore lead on raw health outcomes, with populations that live longer in good health than anywhere else. Countries like the Netherlands and Australia consistently perform well on access and equity in Commonwealth Fund analyses.
The United States is the clearest example of why a single ranking struggles. It spends more per person than any other country, produces world-leading medical research and specialist care, and yet ranks poorly on life expectancy, infant mortality, and equitable access. Whether that makes it 37th or some other number depends entirely on how you weight those competing facts against each other. The WHO’s 2000 ranking made that judgment call. The controversy it generated is precisely why no one has tried it the same way since.
