China's fertility rate dropped from 5.91 children per woman in 1967 to 1.6 in 2012. The one-child policy is a factor behind this development. According to the Chinese Central Government, the one-child policy prevented approximately 400 million births. Experts continue to debate this figure, however. Some argue that such a drop in fertility is typical for a rapidly industrializing country while others believe it actually accelerates the aging process. According to demographer Zhen Binwen of the Chinese Academy of Social Sciences, China's labor force would peak in 2015. Almost 7% of China's population were 65 years or older in 2000, a benchmark after which the United Nations considers a population to be aging. China is in fact aging quite quickly. UN figures show that China's ratio of people aged 60 and over increased 3.8% between 2000 and 2010, higher than the global average of 3% between 1950 and 2010. Therefore, China is one of the developing countries with aging populations. The nation's quickly growing and export-driven economy will slow down, as the advantage of abundant and cheap labor fades away. Life expectancy in China rose from 43 in 1960 to 73 in 2010, thanks to improved standards of living, better nutrition, and access to healthcare and education.
