Demand for elderly care services in China will continue to rise due to the increasing aging population. The number of elderly people aged above 60 was over 200 million in 2012, and will be 300 million in 2025 and 400 million in 2034, according to experts. It will be a tough challenge for China to deal with, due to the increasing rates of urbanization and a decreasing birth rate. The Chinese people will be facing a big challenge if we do not have enough money when we get older. The United Nations defines an aging society as one that has 10 percent of its population at or above the age of 60. When most developed countries were classed as an aging society, their gross domestic product (GDP) per capita stood at between 5,000 to 10,000 U.S. dollars or above. However, China became an aging society in 2001, and its GDP per capita was only 1,000 U.S. dollars. It was 6,000 U.S. dollars in 2012. China’s economic foundation for an elderly society is fragile. On Sept. 13.2013, the State Council issued a guideline to speed up the development of China’s elderly care services, hoping to complete a social care network for its elderly by 2025. 操作提示:通过题干后的下拉框选择题目的正确答案。 1.
