     Today most Chinese teenagers are happy to be favored by two parents and four grandparents in their

families. But have you ever thought about how to take care of four to twelve old people when you grow

up and get married? This could be a problem for most Chinese youths as China is entering new stage of

an aging society.

     An aging society refers to one where lo percent or more of its population is over 60. By the end of 2007,

Chinese over 60 years old have made up 11.7 percent of the nation's total population "China is getting old

before becoming rich," said Cai Chuang, a professor at the Chinese Academy of Social Sciences. The

population increase that has powered Chinese growth for three decades will give way over the next ten years

to a rapid aging of the society. This will lead to weaker economic growth, because of a lack of labor

resources.

     As a result of the family planning policy, it is expected that the country's total working population will

decrease after 2015.

     China is not the only country getting old. More than 60 countries have become aging societies and one

in three people in the European Union is a senior citizen.

     However, experts said that China doesn't have a highly developed social security network to support the

old. Social security is an insurance program protecting those in need, including the old, the disabled and

others.
