Health policies and data

Health Statistics


The OECD carries out work on health data and indicators to improve international comparisons and economic analyses of health systems.

OECD Health Statistics and Health at a Glance are, respectively, the leading statistical database and publication for international comparisons of health and health systems. They help policy makers, researchers, journalists and citizens compare the performance of health systems across OECD and partner countries.

Around 10% of all health spending across OECD countries is paid by private health insurance

After government schemes, social health insurance and out-of-pocket payments, private health insurance is an important source of health financing in many OECD countries. On average, it finances 10% of all health spending across the OECD, but this average masks considerable cross-country variation. Private health insurance accounts for a third of all health spending in the United States, nearly half in Switzerland and around 60% in the Netherlands. On the other hand, in around half of OECD countries it accounts for 5% or less of health spending and plays an almost negligible role in the Czech Republic, Estonia and Sweden. These substantial differences can be explained by the fact that private health insurance plays different roles in countries: It can be the primary way to obtain health care coverage for the entire population of specific population groups or it can supplement, complement or duplicate coverage of a publicly financed benefit package.

Note: Total private health insurance spending is defined as the sum of spending by compulsory private health insurance schemes and voluntary private health insurance schemes. CHE stands for current health expenditure.
* United States: Spending by private health insurance cannot be distinguished between compulsory and voluntary. Since the introduction of the individual mandate to purchase health insurance 2014 as part of the Affordable Care Act, the majority is considered as compulsory.
