How much a country spends on health care over time relative to spending on all other goods and services in the economy can be down to both growth in health spending itself as well as how well the economy is performing overall. In 2016, health spending is estimated to have accounted for 9.0% of GDP on average across OECD countries, largely unchanged in recent years. This comes after a period of health spending growth above that of the overall economy in the 1990s and 2000s that saw health expenditure as a share of GDP rise sharply in many OECD countries.
