China's transformation to a predominantly urban society is key to realizing the government's goals of boosting consumption and raising living standards amid slowing economic growth.
China's vast countryside has lagged far behind urban areas in income growth, public services and job creation, prompting millions of Chinese to move to the cities. With public services in major urban areas such as Beijing, Shanghai and Guangzhou now strained almost to the limit, China is attempting to steer urban growth toward smaller cities with more space to expand.
While the overall population has grown by a relatively small 40 million in the past five years, the proportion aged 59 or under has fallen slightly while the percentage of those 60 or over has grown by 2.89 percent to make up 16.15 percent of the population. That is slightly smaller than the 16.52 percent of the population aged 14 or under.
The bureau's data also showed that China already has 34 million more men than women, a gap that's expected to widen as a result of the traditional preference for male children and the aborting of female fetuses.
