China faces the problem of an ageing population as births decline and their are fewer young people to support senior citizens. The shift to a two child limit after the policy limiting children to one per couple has not accomplished the goal of restoring the birth rate. The Central Committee of the Communist Party and the president Xi Jinping have taken the decision to allow three children per family. 

This comes at a time when the old policy meant a fine of 10 times the disposable income for having a third child. The law was not enforced in all regions but acted to deter larger families. Yet there is a cultural effect of decades of having smaller families that will not be easily overcome with a change in the law. In Latin America smaller families are the result of decades of cultural change towards smaller families. Young people are increasingly aware of the cost of raising and educating an additional child, and the effect on the standard of living. Experts say it is too costly to raise another child  and housing is not cheap in China. 

This discussion with 3 billion comments over Weibo in the discussion of this policy in China last week, misses a more obvious point from the graph shown in this report in The Guardian. That graph shows the curve for the birth rate in 2019 dropping faster in South Korea and Japan than in China, so that in 2019 the birth rate in Japan and South Korea was lower than in China. This shows that even without a one child policy the birth rate in Chia would be closer to that of South Korea after industrialization progressed and society experienced profound cultural and economic change. Japan today has the lowest birth rate in Asia. The Latin American experience also confirms this shift to small families.
