Median age of the population in China 1950-2100

Since 1970, the median age of China’s population has continued to increase from around 20 years to around 37 years in 2015. According to estimates from the United Nations, the increasing trend will slow down when the median age will get close to 50 years in the middle of the 21st century and will remain at around 50 years up to 2100.

China’s aging population

Although the median age of China’s population is still lower than in many developed countries, for example in Japan, the consequences of a rapidly aging population have already become a concern for the country’s future. As the most populated country in the world, the large labor force in China contributed to the country’s astonishing economic growth in the last decades. Nowadays however, the aging population is going to become a burden for China’s social welfare system and could change China’s economic situation.

Reasons for the aging population

Like in many other countries, increasing life expectancy is regarded as the main reason for the aging of the population. As healthcare and living standards have improved, life expectancy in China has also increased. In addition, the one-child policy led to a decreasing fertility rate in China, which further increased the share of older people in the society. Even though the one-child policy has been abolished in 2016, many young people are refraining from having children, largely due to the high costs of raising a child, career pressure and the pursuit of freedom.
