The nine indicators below are the core comparative measures published by OECD Health Statistics: workforce supply (physicians and nurses per 1,000 population), capacity (hospital beds per 1,000), outcomes (life expectancy at birth and infant mortality per 1,000 live births), financing (health spending as a percentage of GDP and per-capita health expenditure in PPP-adjusted US dollars), and prevention (DTP and measles childhood vaccination coverage). Together they form a compact snapshot of how each OECD economy structures, funds, and delivers healthcare.

How to read these rankings. For workforce and capacity indicators, higher numbers usually signal greater access — though once a country crosses a sufficiency threshold, additional supply yields diminishing returns and may reflect overstaffing of acute-care beds rather than better outcomes. Outcome indicators are mostly self-explanatory: longer life expectancy is better, lower infant mortality is better. Financing rankings need interpretation: spending more as a share of GDP does not automatically buy better outcomes (compare the United States, the highest spender, with peers spending half as much at similar or longer life expectancy).

Caveats. Definitions are harmonised across OECD members but country reporting practices still vary — for example, "practising physicians" excludes researchers and administrators in most countries but includes them in a handful, inflating the headline ratio. Hospital-bed counts include both public and private beds, and some countries classify long-term-care beds as hospital beds while others do not. Health-spending series use the System of Health Accounts (SHA 2011) methodology and convert local-currency spending to PPP-adjusted USD to make cross-country comparisons meaningful. Vaccination coverage is the share of children receiving the recommended dose by age 24 months as estimated by WHO and UNICEF jointly.

Release cycle. OECD Health Statistics publishes annually in July with revisions to prior years; some indicators (notably hospital beds and physician density) are reported with a one- to two-year lag because the source administrative data takes time to consolidate. Each row in the rankings below carries the observation year so you can tell at a glance which countries have current data and which are still showing pre-pandemic or transitional vintages.
