I liked this post by u/Cal_Ibre on China's demographics:

. Under the two child policy, a smaller percentage still are.
Unregistered people, called heihaizi (black children) in China do not appear in hospital birth registries, household registries, or the census. Your article claims:
The 2000 census showed that only 14.08 million were born in 2000, but the statistics bureau revised it to 17.71 million. However, there were only 14.26 million secondary students in 2014, and 13.57 million people aged 15 in the 2015 micro-census.
17.71 million is 26% higher than 14.08.
There is no conspiracy by the bureau of statistics to fabricate the population. Every year, births are adjusted to account for unregistered persons, and every year this adjustment follows foreign estimates of the number of unregistered births.
China is aging faster than almost any industrialized country
That's not what your articles say. They say China is aging faster than other industrialized countries
did when they were developing.
According to the UN, it will take China just 20 years for the proportion of the elderly population to double from 10% to 20% (between 2017-2037). The next closest is Japan where it took 23 years. By comparison, it took 61 years in Germany and 64 years in Sweden. China’s dependency ratio for retirees -- those aged 65 or older divided by total working population -- as at 2015 was 14%. The UN estimates this could rise as high as 44% by 2050 with the number of those over 65 rising from approximately 100 million in 2005 to approximately 330 million in 2050, roughly the population of the United States and twice the current population of Russia.
