On average, public spending on health care services amounts to around 6% of GDP, constituting the largest part of total health spending of around 9% of GDP (OECD Health Data). Total health spending is by far highest in the United States, with more than half accounted for by private health spending. Among European countries, France, Germany, Austria and Belgium are the countries with the highest levels of overall spending on health care (in excess of 10%), whereas Estonia, Poland and the Czech Republic spend the least (below 7%). Differences across countries are also substantial when only public expenditures are considered, ranging from 2.6% (Mexico) to almost 8% (Germany and France).
