The US spends more on healthcare than any other country, reaching $2.7 trillion in 2011 or $8,680 per person, while UK spending was 142.8 billion pounds or 9.4% of GDP. In the US, most receive insurance through employers or private purchase, while 31% use public insurance and 16% are uninsured. In contrast, UK citizens receive universal public healthcare through taxation. While the US spends more, it has lower life expectancy and poorer health outcomes than other wealthy nations, including the UK which was rated as having the most efficient and cost-effective system. The data shows clear differences between the privately-run US system and the government-run UK system.
