The low fertility rate in China cannot be reversed in a short time. A National Bureau of Statistics' survey in 2014 showed 43 percent of the targeted group (couples either of whom were the only child of their parents and thus were eligible to have two children) was willing to have a second child. But a National Health and Family Planning Commission survey in early 2015 showed only 39.6 percent of the eligible couples wanted to have two children.

Till the end of May 2015, about 1.45 million couples from across the country applied to have a second child, and about 1.39 million of such applications were approved. But the increase in the number of newborns depends on whether these couples will really have a second child, which, in turn, will be determined by their financial conditions. Only when couples desirous of having two children actually have them can they help gradually correct the population imbalance in China.

But instead of waiting for such a development to take place, the authorities should improve maternal and childcare services, and policies related to them such as risk assessment. And the central and local authorities have to monitor and evaluate the newborn population and fertility rate to ensure medical and health resources are properly distributed.

China could learn from the childbearing welfare policies of countries such as Sweden and Canada, and implement them in the country, albeit with Chinese characteristics. A robust national childbearing policy, after all, can help ease the burden of families that want to have two children and thus improve China's dwindling demographic dividends.
