The US spends more than any other country in the world on healthcare, at an estimated 17.7% of GDP in 2013. However, growth in healthcare expenditure, which was fester than economic growth for many years, has grown at a slower rate than GDP in each of the past three years.
The Economist Intelligence Unit expects healthcare spending to grow by an average of 4.9% a year in 2014-18, raising healthcare spending as a percentage of GDP to 17.9% by 2018. Population growth means that spending per head will rise by an average of 4.1%.
High US healthcare expenditure is partly explained by problems in incentive structures for healthcare providers and the system of relatively fragmented private coverage, which reduces negotiating power vis-a-vis providers and raises overheads. Many other rich countries have central negotiations with healthcare providers or set prices centrally, and this limits costs.
