According to the internationally accepted standard, a region in which the percentage of the population aged 65 and over has reached 7 percent is called an aging society. When the population that is age 65 and over reaches 14 percent, It is called an “aged” society. When those over 65 exceeds 20 percent, it is called a “hyper-aged” society.
According to China’s 7th National Census data, in 2020, 149 cities had a population in which those over 65 years of age exceeded 14 percent, thus becoming “aged” cities. In terms of regional distribution, 41 of them are from the eastern coastal region, 36 are from the northeast region, and 72 are from the central and western regions. Overall, the “aged” cities are concentrated in the northeast and the central region, the Yangtze River Delta, the middle and lower reaches of the Yellow River, and the Chengdu-Chongqing city clusters.
A major reason is the exodus of young adults and the low percentage of working age population. The eastern cities of Shandong, Jiangsu and Zhejiang have many “aged” cities. In these more economically developed regions, the fertility rates tend to stay low.
