The United States has been the subject of international healthcare comparisons for decades. The data is not new, and the broad pattern it reveals has been consistent across administrations of both parties, across different methodologies, and across different organizations doing the measuring. The United States spends more on healthcare than any other wealthy country — substantially more — and does not achieve the best outcomes across most standard measures of population health. This combination — highest spending, mediocre outcomes — is the defining feature of American healthcare in comparative perspective, and understanding what produces it is a prerequisite for evaluating any serious reform proposal.
This article puts the comparative data in one place: spending, coverage, outcomes, administrative costs, and access. It draws primarily on the Commonwealth Fund, the Organisation for Economic Co-operation and Development, and the World Health Organization — the three most widely used sources for international health system comparisons — and notes where the data requires interpretive care. The goal is not to use the comparisons to argue for a specific reform path. It is to establish what the United States is actually getting for what it is actually spending, and how that compares to what peer countries are getting for what they spend. That comparison does not determine what the right policy response is. It does establish the scale of the gap that any serious reform must be evaluated against.
The detailed examination of how specific peer countries have structured their systems is in How Other Countries Have Achieved Universal Coverage. The administrative cost dimension is examined in depth in The Administrative Burden and What It Costs.
Spending: How Much More, and Why
The United States spent approximately $12,500 per capita on healthcare in 2022 — more than double the average of comparable wealthy countries, which spent approximately $5,500 per capita. This gap has persisted and widened over several decades. It is not a recent development or a product of any particular administration’s policies. It is a structural feature of the American system that has compounded over time.
The countries used for comparison matter. The peer group typically used in serious comparative work includes countries that are economically comparable to the United States — high-income democracies with advanced healthcare systems — and excludes countries with fundamentally different economic structures. The Commonwealth Fund’s standard comparison group includes Australia, Canada, France, Germany, the Netherlands, New Zealand, Norway, Sweden, Switzerland, and the United Kingdom. Switzerland is the second-highest spender in this group at approximately $7,400 per capita — roughly 60 percent of U.S. spending. Most peer countries spend between $4,000 and $6,000 per capita.
The explanation for the spending gap is one of the most carefully studied questions in health economics, because it is central to understanding what reform would need to change to reduce costs. The dominant finding, replicated across multiple research approaches, is that the United States pays higher prices per unit of healthcare service — not that Americans use dramatically more services.
A landmark analysis examining utilization and price data across countries found that Americans did not use dramatically more physician visits, hospital days, or prescription drugs than people in peer countries — but paid substantially more per unit for what they did use. Hospital prices in the United States are higher than in peer countries for comparable procedures. Physician fees are higher. Drug prices are higher. Administrative costs are higher. The spending gap is not primarily a utilization problem; it is a price and overhead problem.
This distinction matters for policy because utilization-focused interventions — managed care, high-deductible health plans, prior authorization — address a different problem than price-focused interventions. The evidence that utilization management reduces costs is mixed and often finds that it reduces low-value and high-value utilization without reliably distinguishing between them. The evidence that price structure drives the spending gap points toward interventions that change the mechanisms by which prices are set — centralized negotiation, all-payer rate setting, administrative simplification — rather than mechanisms that manage individual patients’ care decisions.
Coverage: The Unique American Gap
The United States is the only wealthy country that does not provide universal health coverage to its population. Every other country in the standard peer comparison group — and indeed virtually every high-income country in the world — provides some form of universal or near-universal coverage. The United States has approximately 25 to 30 million uninsured residents and a substantially larger underinsured population whose nominal coverage does not protect them from significant financial harm when they need care.
The coverage gap produces measurable effects on healthcare utilization that are different from the effects in countries with universal coverage. Americans are significantly more likely than people in peer countries to report forgoing needed care due to cost. Commonwealth Fund surveys conducted annually ask representative samples in each peer country whether they have skipped a doctor visit, a recommended test, a prescription, or a follow-up appointment because of cost in the past year. The United States consistently shows the highest rates of cost-related care avoidance — by a substantial margin. In a typical survey year, approximately 30 to 40 percent of American adults report forgoing care due to cost, compared to rates in the low single digits in countries with universal coverage.
Cost-related care avoidance is not a neutral consumption choice. It is a healthcare access failure with clinical consequences. The person who does not fill a prescription for a blood pressure medication because the copay is prohibitive is not making a low-stakes financial decision — they are accepting elevated cardiovascular risk. The person who delays investigating a symptom because they cannot afford the specialist visit is not being cautious about healthcare utilization — they may be allowing a treatable condition to progress to a less treatable stage. The aggregate effect of cost-related care avoidance on population health is real and has been documented in research that finds worse outcomes for conditions where early intervention is effective.
The uninsured population is disproportionately concentrated in states that did not expand Medicaid under the Affordable Care Act — primarily Southern states — and disproportionately represented among working-age adults, Latino and Black Americans, and low-wage workers in industries that do not offer employer-sponsored coverage. The coverage gap is not randomly distributed; it tracks existing inequities in income, geography, and race in ways that compound those inequities rather than correcting them.
Health Outcomes: The Return on Spending
If the United States’ high healthcare spending produced the best health outcomes among wealthy countries, the spending level might be evaluated differently. It does not. Across most standard measures of population health, the United States performs at or below the wealthy-country average despite spending roughly twice as much per capita as the average peer country.
Life expectancy. American life expectancy at birth is lower than in most peer countries — approximately 77 years in recent data, compared to 81 to 84 years in most Western European countries, Canada, Australia, Japan, and South Korea. The gap has widened over the past several decades. American life expectancy actually declined in the years following 2014, driven by the overdose crisis, rising suicide rates, and the reversal of previous gains in cardiovascular mortality — a pattern that has no parallel in peer countries and that reflects the intersection of the healthcare system’s failures with broader social determinants of health.
Infant mortality. The United States has an infant mortality rate — deaths in the first year of life per 1,000 live births — that is substantially higher than most peer countries. The U.S. rate is approximately 5.4 per 1,000 live births, compared to rates of 2 to 3 in Japan, Norway, Finland, and several other peer countries. The infant mortality gap reflects both healthcare system factors — access to prenatal care, quality of perinatal services — and social determinants that lie outside the healthcare system, including poverty rates, housing stability, and nutrition.
Maternal mortality. The United States has the highest maternal mortality rate among wealthy countries, and the gap is large. American maternal mortality is approximately 22 to 24 deaths per 100,000 live births — compared to rates of 2 to 8 in most peer countries. The U.S. maternal mortality rate is three to ten times higher than the rates in comparable wealthy nations, and it has increased rather than decreased in recent decades while peer country rates have continued to decline. The maternal mortality gap is the most dramatic single outcome disparity in the international comparison data and has been the subject of sustained research attention. The findings consistently identify failures in the recognition and management of obstetric emergencies, racial disparities in how Black women’s symptoms and concerns are responded to by providers, and the geographic access problems documented in The Rural Healthcare Crisis as contributing factors.
Preventable mortality. The Commonwealth Fund and OECD track “amenable mortality” — deaths from conditions that timely and effective healthcare should be able to prevent. The United States has higher rates of amenable mortality than most peer countries, meaning that more Americans die from conditions that a well-functioning healthcare system should have prevented or treated. This measure is specifically designed to capture the healthcare system’s contribution to mortality, separate from the social determinant factors that affect population health more broadly. The U.S. performance on amenable mortality is significantly worse than the wealthy-country average.
Chronic disease burden. The United States has higher rates of obesity, diabetes, and cardiovascular disease than most peer countries — a chronic disease burden that is both a driver of healthcare spending and a contributor to the outcome gaps described above. The chronic disease burden reflects both healthcare system factors — the adequacy of preventive care, the management of risk factors before they progress to disease — and social determinants, including diet, physical activity patterns, and the food environment. Attributing the chronic disease gap entirely to the healthcare system is not appropriate; attributing none of it to the healthcare system is equally inappropriate.
Cancer outcomes. The United States performs well, relative to peer countries, on cancer survival rates for several major cancers — particularly breast cancer, colorectal cancer, and prostate cancer. This is a genuine area of comparative strength and is attributed to higher rates of cancer screening and earlier detection, as well as access to advanced treatment technologies. The cancer survival advantage, however, is distributed unequally within the United States — insured patients have substantially better cancer outcomes than uninsured patients — and does not offset the overall outcome gaps documented across other measures.
Administrative Costs: The Overhead Gap
The administrative cost comparison is among the most methodologically robust and consistently replicated findings in international health system research. The United States spends a dramatically higher share of healthcare expenditures on administration than any peer country, and the difference is attributable to system structure rather than to clinical or managerial factors.
A widely cited study estimated that billing and insurance-related administrative costs consumed 34.2 percent of healthcare expenditures in the United States, compared to approximately 12 percent in Canada’s single-payer system. More recent research using updated data has found similar ratios. The OECD tracks government and insurance administrative expenditures as a share of total health expenditure across member countries; the United States consistently shows the highest administrative share.
The mechanisms producing the administrative overhead are described in detail in The Administrative Burden and What It Costs. The relevant comparative point is that the overhead gap is not explained by American healthcare being more complex to administer in clinical terms — it is explained by the multi-payer billing environment that requires every provider to maintain billing relationships with dozens of distinct payers, each with different coverage rules, authorization requirements, and payment systems. Countries with single-payer or regulated multi-payer systems that standardize billing do not generate comparable administrative overhead.
The scale of the administrative overhead gap — hundreds of billions of dollars annually — is significant for the cost reform debate. If the United States could reduce its administrative costs to the level of a high-performing regulated multi-payer system, the savings would be sufficient to finance a substantial expansion of coverage without increasing total healthcare spending. This arithmetic does not determine what reform approach is correct, but it does identify administrative overhead as one of the largest addressable contributors to the spending gap.
Access: Timeliness and Primary Care
Coverage and spending comparisons capture part of the access picture, but they do not capture the timeliness dimension — whether people can get care when they need it. This is an area where the international comparison produces more mixed results for the United States.
The Commonwealth Fund tracks wait times for specialist appointments, same-day or next-day primary care access, and after-hours care availability. The United States generally performs comparably to or better than peer countries on specialist wait times for elective procedures — a finding that reflects the volume of specialist capacity in the U.S. system and the ability of well-insured patients to access that capacity. Countries with universal coverage but constrained specialist capacity — Canada, the United Kingdom — have longer wait times for certain elective specialist appointments.
The United States performs poorly on primary care access. A substantial share of Americans report difficulty accessing primary care when they need it — finding a physician who is accepting new patients, getting a timely appointment, or reaching their provider outside office hours. This primary care access problem is more severe than in most peer countries, reflecting the relative underinvestment in primary care relative to specialty care that characterizes the American system.
The access picture is also highly unequal within the United States in ways that aggregate comparisons obscure. A well-insured patient in a major metropolitan area with ample specialist capacity has a different access experience than an uninsured patient in a rural county with no primary care physician accepting new Medicaid patients. International comparisons that compare country averages understate the within-country variation that is one of the most distinctive features of American healthcare access.
What the Comparisons Do and Don’t Tell Us
International health system comparisons are a powerful analytical tool, but they require interpretive care. Several caveats are worth stating explicitly.
Countries differ in many ways beyond their healthcare systems. The social determinants of health — income inequality, housing stability, food security, racial and ethnic composition, rates of violence, and many others — differ across countries in ways that affect health outcomes independently of healthcare system design. The United States has higher income inequality, higher poverty rates, and higher rates of gun violence than most peer countries, all of which affect population health in ways that the healthcare system cannot fully compensate for. Attributing the entire U.S. outcome gap to the healthcare system is not appropriate; the healthcare system is one contributor among several.
Healthcare system structure and outcomes have a complicated causal relationship. The direction of causation between system structure and outcomes is not always clear. Countries with universal coverage have better average outcomes, but universal coverage did not cause all of those better outcomes — countries that built universal coverage systems also made other policy investments, in social welfare, in public health infrastructure, in housing and income support, that contribute to better health. The peer-country comparison establishes that universal coverage is compatible with better outcomes at lower cost; it does not establish that universal coverage alone produces those outcomes.
The peer country evidence base has limits for the U.S. context. The United States is the largest, most heterogeneous, and most politically complex of the peer countries. System designs that work well in countries with smaller, more homogeneous populations and different political structures may face different implementation challenges in the U.S. context. This does not make the peer-country evidence irrelevant, but it does mean that direct policy transplantation is not straightforward.
These caveats do not undermine the basic conclusions the comparative data supports: that the United States spends dramatically more than peer countries, achieves worse average outcomes across most measures, has unique coverage gaps, and generates administrative overhead that consumes a share of spending with no parallel elsewhere. The comparisons establish the scale of the gap. They do not, by themselves, determine the right path for closing it — that is the work of the reform debate examined in The Full Range of Reform Proposals and How Other Countries Have Achieved Universal Coverage.
What the data does establish, clearly and consistently, is that the American healthcare system’s combination of high spending and mediocre outcomes is not an inevitable feature of advanced healthcare — it is the product of specific structural choices that other wealthy countries have made differently. Understanding those choices, their consequences, and what changing them would require is what the rest of this hub is for.
