Why do countries with more doctors not always live longer?
More doctors do not automatically mean longer lives because income, diet, sanitation, smoking and violence shape life expectancy as much as physician supply does. The chart makes this plain: 63 countries have more doctors per person than Japan's 2.65 per 1,000 yet shorter life expectancies, including Georgia at 5.64 doctors per 1,000 and 74.7 years, and Russia at 5.11 and 73.4 years. Monaco, the longest-lived country in the set at 86.5 years, pairs that record with 8.61 doctors per 1,000, but Japan reaches 84.0 years with far fewer.
The Economics Observatory notes that in the UK, healthy life expectancy has fallen even as medicine advances, and points to obesity, mental health and musculoskeletal conditions as key drivers of lost healthy years, factors that more doctors alone do not fix.2 Nurses, midwives, pharmacists and the broader health system are not captured in a physician count, and doctors tend to cluster in cities, leaving rural areas with far less coverage than a national average suggests.
What is happening to Cuban doctors abroad and at home?
Cuba's overseas medical missions are shrinking rapidly under US pressure in 2026. Guatemala, Guyana, Jamaica, Honduras, Paraguay and St. Vincent and the Grenadines have phased out or ended their arrangements, and the State Department's August 2026 report counted 15,000 to 18,000 Cuban medical workers in 51 countries, down from 24,000 in more than 58 countries at the start of 2025.3 Uruguay, where 21 Cuban eye doctors have operated since 2005, is now under formal US warning that it risks losing State Department assistance if it keeps the program.3
The debate over the missions is sharp. The US State Department calls the program "forced labor" and "human trafficking," citing passport confiscation and underpayment.1 William LeoGrande, a professor of government at American University, says the countries ending contracts are acting out of fear: "This is typical of Donald Trump's foreign policy, which is based essentially on coercive diplomacy."1 Stephanie Panichelli-Batalla, a professor at the University of Warwick, argues the program "is, in fact, much more complex," noting that doctors volunteer, earn more than they would at home, and return with a higher standard of living, while also acknowledging that passport confiscation is a genuine long-standing problem.1 Cuba's latest doctor count in the chart is from 2021, so none of the 2026 departures are reflected in the data.
Which countries and regions have the worst doctor shortages?
The worst doctor shortages are concentrated in the countries where life expectancy is already lowest. In the 25 countries where people live under 65 years, the median is 0.17 doctors per 1,000 people, meaning fewer than one physician for every 5,000 residents. These are predominantly lower-resource nations in sub-Saharan Africa and parts of South Asia, the same communities that Cuba's medical brigades have historically served, including Angola, Guatemala and Venezuela.1
Panichelli-Batalla raises the direct consequence of the mission rollbacks for these places: "If we start canceling all those programs, what is going to happen with those vulnerable communities that will lose access to health care?"1 The chart's national averages also mask sharp internal gaps: doctors cluster in cities, so rural and deprived areas within any country can have far fewer physicians than the headline figure suggests. The Economics Observatory finds that in England, men in the most deprived areas can expect 49.8 years in good health, against 69.2 years in the least deprived, a gap of nearly 20 years.2
What do health economists say drives life expectancy differences?
The Economics Observatory points to a broad set of factors beyond physician supply that drive differences in life expectancy: advances in sanitation and public health, the decline of infectious diseases through antibiotics and vaccines, and improvements in maternal care have all contributed to longer lives over the past century.2 But in some rich countries, progress has stalled. In the UK, healthy life expectancy fell to 60.9 years for women and 60.6 for men in the period from 2022 to 2024, the lowest since reporting began in 2011, driven by rising obesity, mental health conditions among young people and musculoskeletal problems among older workers.2
The Economics Observatory notes that Italy and Japan show longer lives do not necessarily mean more years in poor health, suggesting that diet, lifestyle and social conditions play a distinct role from doctor counts alone.2 Obesity and excess weight are estimated to cost the UK economy 31 billion pounds a year in lost productivity, illustrating how health shapes economic output as much as economic conditions shape health.2 The chart's own limits echo this: income, diet, sanitation, smoking and violence all shape life expectancy alongside the number of physicians.
How many doctors are in the US per 1,000 people?
The United States has 3.68 doctors per 1,000 people, more than twice the median of 1.67 across the 180 countries in the chart. That puts the US well above Japan's 2.65 and above the median of 3.7 found in the 38 countries where people live 80 years or more. Yet US life expectancy stands at 78.9 years, in the same band as Cuba's 78.3 and well below Japan's 84.0.
For Americans choosing 2027 health plans during open enrollment, which runs to January 15, the comparison is a useful reference point: a relatively high doctor supply does not place the US among the longest-lived nations. The chart does not capture nurses, midwives or pharmacists, and a national average conceals wide gaps between cities and rural areas, where physician shortages can be severe.
