Population experts including Liang Zhongtang a demographer at the Shanghai Academy of Social Sciences, are not convinced the change in the one-child policy in 2013 will have come in time to reverse the trend in increase of elderly population relative to the younger population. Zhongtang says the whole policy should have been removed. According to UN projections China's labor force will lose 67 million workers from 2010 to 2030. During this period the elderly population is expected to increase from 110 million in 2010 to 210 million in 2030. Wang Feng, a demographer at Fudan University in Shanghai, is skeptical about how much difference the new policy will make. He says the figures by population experts showing a maximum of 2 million additional childbirths over the next 3 years, starting about 10 months from now won't make much difference, and these additions will not enter the labor force for another 20 years.
