More than half the world’s countries have some form of national healthcare, though the systems vary dramatically in how they’re funded, who delivers the care, and what’s actually covered. The list includes most of Western Europe, Canada, Australia, Japan, South Korea, Taiwan, and dozens of other nations across every continent. What unites them is a commitment to covering all (or nearly all) residents, but how they get there differs enough that “national healthcare” doesn’t mean one thing.
Three Main Models, Dozens of Variations
National healthcare systems generally follow one of three blueprints. Understanding which model a country uses tells you far more than just knowing it has universal coverage, because the day-to-day experience of getting care looks quite different under each one.
The first is the government-run model, sometimes called the Beveridge model after the architect of Britain’s National Health Service. Here, the government both pays for and largely delivers healthcare through tax revenue. Many hospitals and clinics are publicly owned, and doctors may be government employees, though private physicians also participate and collect fees from the state. Countries using this approach include the United Kingdom, Spain, Norway, Sweden, Denmark, Finland, and New Zealand. Italy and Portugal also run variations of this system.
The second is the social insurance model, built around “sickness funds” financed jointly by employers and employees through payroll deductions. Doctors and hospitals tend to be private. Germany, where the system originated, has roughly 240 different insurance funds, but tight government regulation keeps costs controlled in a way that resembles single-payer systems. Countries using this model include Germany, France, Belgium, the Netherlands, Japan, and Switzerland, with variations found across parts of Latin America.
The third is the national health insurance model, where the government runs a single insurance program but care is delivered by private doctors and hospitals. Canada and Taiwan are the clearest examples. South Korea and Australia also use versions of this approach. Taiwan’s system contracts with about 93% of all medical institutions nationwide, and patients can visit any facility freely, paying only a small fixed copayment. Taiwan’s administrative costs are among the lowest in the world, under 1% of total medical expenses, largely because claims processing is fully automated.
Full List by Region
The countries below all provide some form of publicly funded healthcare to their populations, though coverage depth and quality vary considerably.
- Europe: United Kingdom, France, Germany, Spain, Italy, Sweden, Norway, Denmark, Finland, Netherlands, Belgium, Switzerland, Austria, Portugal, Ireland, Iceland, Luxembourg, Greece, and most of Central and Eastern Europe including Poland, Czech Republic, Hungary, Croatia, Slovenia, Romania, and Bulgaria
- Asia-Pacific: Japan, South Korea, Taiwan, Thailand, Australia, New Zealand
- Americas: Canada, Brazil, Cuba, Costa Rica, Argentina, Chile, Colombia, Mexico
- Middle East and Africa: Israel, Turkey, Saudi Arabia, Rwanda, Ghana, South Africa (in transition)
Many middle-income countries are still expanding their systems. Ghana’s National Health Insurance Scheme, for instance, has been running for over a decade but covers only about 36% of the population and faces financial sustainability challenges. Thailand has made faster progress by separating the organizations that purchase care from those that provide it and creating an oversight board with civil society participation. Brazil has been experimenting with new ways of contracting primary care at the state level to improve both efficiency and quality.
What National Healthcare Costs
One of the most striking facts about national healthcare systems is that they cost less than the U.S. system, which lacks universal coverage. In 2024, the United States spent 17.2% of its GDP on health. Comparable high-income countries with national systems, including Australia, Canada, France, Germany, Japan, the Netherlands, Sweden, Switzerland, and the United Kingdom, averaged 11.2% of GDP. That gap has persisted for decades, and it widens most on administrative costs and drug prices.
Lower spending doesn’t always mean identical access, though. These systems make trade-offs, and the most visible one is wait times.
The Trade-Off: Wait Times
In a 2025 OECD survey of ten countries with national healthcare, 18% of people reported waiting more than a week to see a primary care provider, and over half waited two days or longer. Canada, New Zealand, and France had the longest waits for basic appointments.
Specialist care is where the delays become more noticeable. On average, 52% of people across surveyed countries waited a month or more to see a specialist. In Canada and the United Kingdom, more than 10% of patients reported waiting over a year. These long waits for non-urgent specialist care are one of the most common criticisms of tax-funded systems, and both countries have made reducing them a policy priority.
The UK’s NHS, for example, is investing an additional £485 million in GP contracts for 2026-27, bringing the total estimated value to nearly £13.9 billion. Part of that funding is specifically aimed at recruiting more general practitioners and ensuring that clinically urgent patients are seen the same day. New rules will also prevent online consultation systems from capping the number of patient requests during working hours.
What’s Typically Not Covered
Having national healthcare doesn’t mean everything is free at the point of use. Most systems exclude or limit coverage for dental care, vision correction (eyeglasses and contact lenses), and hearing aids beyond a basic allowance. Prescription drug coverage varies widely: some countries cover nearly all medications with small copayments, while others require supplemental insurance for prescriptions.
Cosmetic procedures, fertility treatments, and private hospital rooms are commonly excluded. Mental health services are technically covered in most systems but often face the longest wait times and the thinnest staffing, creating a gap between what’s promised on paper and what’s available in practice.
Many countries have developed a two-tier reality where public coverage handles the essentials and private insurance fills in the gaps. In the UK, roughly 10% of the population carries private insurance to access faster specialist appointments. In France, most residents buy supplementary insurance (known as a “mutuelle”) to cover copayments and dental or optical care. In Australia, the government actively incentivizes private coverage through tax penalties for higher earners who don’t carry it.
Why the U.S. Is the Outlier
The United States is the only wealthy, industrialized nation without a universal healthcare system. It uses a patchwork of employer-sponsored insurance, government programs for specific populations (Medicare for seniors, Medicaid for low-income residents, and the VA system for veterans), and individual market plans. This hybrid means Americans interact with elements of every model described above, but without the unified cost controls or guaranteed coverage that define national systems elsewhere.
The result is higher spending, higher administrative overhead, and a population where coverage depends heavily on employment status, age, income, and state of residence. Countries that implemented national healthcare typically did so in the decades following World War II, when there was broad political consensus for social safety nets. The U.S. came close several times but never crossed that threshold, and the existing infrastructure of private insurance has made the transition increasingly complex to envision.
