Aging tsunami coming: the main finding from China’s seventh national population census

China is undergoing great social changes, and its demographic makeup is shifting every year along with those changes. China released key indicators from the seventh national population census on 12 May 2021. The total population of China’s mainland increased to 1.41178 billion in 2020 from 1.33972 billion in 2010 (sixth national population census) with an average annual growth rate of 0.53%. In the past 10 years, the share of the population aged above 60 and 65 years increased by 5.44% (from 13.26% in 2010 to 18.70% in 2020) and 4.6% (from 8.9 to 13.5%), respectively. The share of the population with a college education or above rose from 8.93% in 2010 to 15.47% in 2020, and the illiteracy rate dropped from 4.08% in 2010 to 2.67% in 2020. In the next decade, China is likely to face many changes, including the increasing proportion of older adults in the population, declining births, and economic transformation. In an effort to respond to the changed demographic landscape, the authorities should adopt new laws and strategies to improve government services for older adults and consider ways to support women and families and make childbearing more attractive to and feasible for women.
