So, this is population chart and population pyramid  for China. The dependency ratio is 38.8, it’s low.

The birth rates of China have a slightly increase recently, while the death rates have a mineral decline. With the comparison of both sides of the population pyramid, the numbers of female and male are mostly balanced in most the age groups. But for cohorts under 40, there are fewer women/girls. Also, there is a large amount of population in the suitable workers’ age group. Accordingly, China now is on the stage 4, with two convex sides on the population pyramid, it’s a contracting population pyramid, where peoples have longer life expectancy with low birth rate and low death rate.

The big concern for China is the aging population that will require more social services and a lack of a workforce to pay for that. That’s why they recently exchanged the One Child Policy into a Two Child Policy.
