Expenditure on health gives a measure of the final consumption of health goods and services (i.e. current health expenditure). This includes spending by all types of financing arrangements (such as government-based programmes, social insurance and out-of-pocket spending) on medical services and goods, population health and prevention programmes, as well as administration of the health system.

I’d like some clarity as this chart on its face is pretty damning.
