China's population growth has slowed dramatically in recent decades due to its very low fertility rate of 1.4 children per woman, well below replacement level. This is causing China's population to rapidly age. Younger populations are declining while older populations are increasing faster than projected. In addition, more Chinese are pursuing higher education, reducing the supply of young workers. As a result, China faces challenges around a declining and aging workforce, as well as fiscal challenges supporting its growing elderly population. This demographic shift will require substantial economic and policy changes for China.
