Introduction
 
Data - Animation
China's Population by Age & Sex, 1950 - 2050 (population in 1000)
Male Female  
In this animated population pyramid one can watch population change in China unfold over a 100 year period - between 1950 and 2050.
For the period 1950 to 1995 the pyramid is based on population estimates of the UN Population Division; the data for 2000 to 2050 are from the most recent medium variant UN population projection.

One can see how the "baby boom" generation from the 1960s and early 1970s "moves up" the age pyramid. The animation also visualizes the aging of the Chinese population, which is caused by the significant fertility decline since the mid-1970s (and the further increase in life expectancy). Within the next 3 decades the number of elderly people in China will increase massively (see also the discussion of China's aging problem).
