Abstract: China’s Sixth Population Census suggests that in the first ten years of the 21st century,population profile clearly exhibits different characteristics from the past.On the one hand,the growth of population size has been effectively curbed,and fertility has become even lower.Meanwhile,population age structure has been changed greatly: the proportion of those under age 15 in the total population has dropped fast,while the pace of population aging has been faster than expected.Moreover,the problem of sex ratio at birth has become even more severe,and population distribution has largely reshaped.Migration has been an important driving force of these changes.On the other hand,it is clear that China’s population profile has become more complicated than earlier years,and population size,quality,structure and distribution are interrelated,intertwined and interdependent.These present challenges to the government in terms of how to reformulate public policies to solve population-related issues currently and in the future.This forum invites Xuejun Yu from National Population and Family Planning Commission of P.R.China,Xin Yuan from Nankai University,and Rongqing Huang from the Institute of Population Studies,Capital University of Economics and Business,to discuss aforementioned important issues from various perspectives utilizing the latest population census data.They examine the trajectory of population change with a particular focus on population size,structure,and distribution,as well as future population policy.
