In 2013, health expenditure (excluding investment in the health sector) represented 6.9% of GDP in Korea and is estimated to have increased further to 7.1% of GDP in 2014. Still, the health spending share of GDP remains much lower than the OECD average in 2013 (8.9%). This was about two-thirds of the OECD average and half of the G7 average. Health expenditure per capita in real terms (adjusted for inflation) more than doubled between 2003 and 2013, whereas it increased by only about 1.5 times across the OECD on average.
