Universal Health Coverage
The global UHC Service Coverage Index rose from 45 in 2000 to 68 out of 100 by 2021, but progress has stalled since 2015. About 4.5 billion people — more than half the world — are still not fully covered by essential health services, and over 1 billion face catastrophic out-of-pocket spending. Coverage remains highest in Europe and the Western Pacific and lowest across Africa.
Key Universal Health Coverage Insights
Coverage Rose, Then Stalled
The global UHC Service Coverage Index climbed from 45 in 2000 to 68 out of 100 by 2019 and stayed flat through 2021. The annual rate of improvement slowed from 1.5% over 2000–2015 to just 0.5% afterwards, as the COVID-19 pandemic diverted resources and service coverage fell in 84 countries between 2019 and 2021.
Billions Still Left Behind
In 2021 roughly 4.5 billion people — more than half the global population — were not fully covered by essential health services. Coverage is highest in the Western Pacific (80), Europe (79) and the Americas (77) and lowest in the African Region (46), so the people furthest from coverage are concentrated in the poorest settings.
Health Costs Push People Into Poverty
More than 1 billion people — about 14% of the world — faced catastrophic out-of-pocket health spending exceeding 10% of their household budget in 2019, up 76% since 2000. Roughly 1.3 billion were pushed or pushed deeper into poverty by health costs, including 300 million already living in extreme poverty.
Coverage and Protection Diverge
Even as service coverage expanded, financial protection worsened. Fewer than a third of countries improved on both fronts over two decades. The poorest households are hit hardest: 3 in 4 of the poorest experienced financial hardship from health costs, versus fewer than 1 in 25 of the wealthiest.
Global UHC Service Coverage Index (2000–2021)
Population-weighted index, 0–100 scale
Key Finding: The index rose from 45 in 2000 to 68 by 2019 but flatlined through 2021 as the pandemic stalled gains — far off the pace needed to reach universal coverage by 2030.
UHC Service Coverage Index by WHO Region (2019)
Index value, 0–100 scale
Key Finding: Coverage is highest in the Western Pacific (80), Europe (79) and the Americas (77) and lowest in the African Region (46), a 34-point gap between the best- and worst-covered regions.
People Not Fully Covered by Essential Services (2021)
Billions of people
Key Finding: About 4.5 billion of the world's roughly 7.9 billion people were not fully covered by essential health services in 2021 — more than half the global population.
Catastrophic Out-of-Pocket Health Spending (2000–2019)
Billions of people spending over 10% of household budget on health
Key Finding: The number of people facing catastrophic health spending rose 76% since 2000, passing 1 billion in 2019 — financial protection has steadily worsened.
Annual Rate of Service-Coverage Improvement
Annualized change in the service coverage index (%)
Key Finding: Gains in service coverage slowed to one-third their earlier pace, from 1.5% a year over 2000–2015 to just 0.5% a year afterwards.
Understanding Universal Health Coverage Data
What the Service Coverage Index measures
SDG indicator 3.8.1, the UHC Service Coverage Index (SCI), is the geometric mean of 14 tracer indicators grouped into four areas: reproductive, maternal, newborn and child health; infectious diseases; non-communicable diseases; and service capacity and access. It is reported on a 0–100 scale, where higher values mean broader coverage. The global figure is population-weighted, so large countries such as China, India and Indonesia heavily shape the trend.
Catastrophic spending and financial protection
SDG indicator 3.8.2 tracks the share of people facing catastrophic out-of-pocket health spending — payments exceeding 10% (or 25%) of a household's total budget. A related measure counts people impoverished by health costs, pushed below or further below the poverty line after paying out of pocket. Together these capture whether using health services causes financial hardship.
Why coverage does not equal quality
The SCI measures whether services are received, not how good they are. A high index can mask gaps in quality, effective treatment or outcomes, and tracer indicators are proxies rather than a full picture of every service a population needs. Effective-coverage measures that adjust for quality typically score lower than the headline SCI.
Caveats and data lags
Figures combine survey, administrative and modelled data, so they carry uncertainty and are revised as new evidence arrives — WHO's 2024 update restated the global series (54 in 2000 to 71 in 2023). The numbers on this page follow the 2023 Global Monitoring Report, which reports 2021 service-coverage data and 2019 financial-protection data, the latest fully comparable years in that report.
