In November 2013, the government announced that it would loosen decades-long one-child population policy, allowing couples to have two children if one of them is an only child.

The change of policy is of great importance and a practical step toward balanced population development in China.

The one-child policy was introduced in the late 1970s to rein in the surging population by limiting most urban couples to one child. The policy was later relaxed and if both parents were only children they could have a second child regardless.

With the one-child policy, authorities believed they had set the stage for an economic boom and social advancement, and there is no doubt that the policy has been very effective in that respect.

Statistics from the National Health and Family Planning Commission (NHFPC) contend that China's population (1.34 billion) would be 400 million higher were it not for the policy.

The latest change comes as Chinese society ages and the growing burden of social pensions poses great challenges to society as a whole.

The falling birthrate that resulted, however, has thrown the growth of the aging population into sharp focus and led to shrinkage of the working-age population.

China's sixth national census in 2010 showed a fertility rate between 1.5 and 1.6, almost the same as some developed countries which are now plagued by aging populations.

China's peak population should be about 1.5 billion with a birthrate around 1.8. In addition, the labor force (940 million) decreased by 3.45 million in 2012, the first absolute decrease, and is expected to decrease by about 29 million by the end of the decade.

The elderly population meanwhile, keeps on growing with those aged 60 and over numbering nearly 200 million, 14.3 percent of the total, far ahead of the international norm of 10 percent. The figure is forecast to exceed one third of the population by 2050.
