By the mid-2010s, it has already become apparent that China was facing a serious demographic crisis as the population of retirees boomed while the number of working-age people shrank. This poses serious challenges for any attempts to implement social support for the elderly and imposes constraints on China's future economic prospects. In 2018, about 17.8% of China's population, or around 250 million people, was at least 60 years old. The Central Government has been considering raising the retirement age, like many other countries have done, though this is controversial among the Chinese public, who dislike postponing their pensions. As of 2020, China's retirement age is 60 for men and 55 for women working for the government or in other white-collar jobs. But China's demography is such that the nation's pension funds will be "insolvent" by 2035 if current trends continue, according to an official report.
