Although China has made remarkable economic progress over the past few decades, its citizens' health has not improved as much. Since 1980, the country has achieved an average economic growth rate of ten percent and lifted 400–500 million people out of poverty. Yet Chinese official data suggest that average life expectancy in China rose by only about five years between 1981 and 2009, from roughly 68 years to 73 years. (It had increased by almost 33 years between 1949 and 1980.) In countries that had similar life expectancy levels in 1981 but had slower economic growth thereafter -- Colombia, Malaysia, Mexico, and South Korea, for example -- by 2009 life expectancy had increased by 7–14 years. According to the World Bank, even in Australia, Hong Kong, Japan, and Singapore, which had much higher life expectancy figures than China in 1981, those figures rose by 7–10 years during the same period.
