【Abstract】The article, applying the Dynamic Monitoring and Survey over Migrating Population of China in 2013, explores the changing status of the sex ratio at birth of migrating population as well as those key factors which lead to a high ratio and key regions where people migrate in or out. The result shows that the sex ratio at birth of migrating population, rising at first and then dropping, is 119.43 from 2001 to 2013, which is slightly higher than that of the total population. It indicates that migrating population shall be given serious consideration. The control over the sex ratio at birth of migrating population shall focus on people with their second child, with rural hukou (China’s nationwide household registration system), or migrating across provinces, especially those moving from the central and western regions of China to the east region. Thus, we suggest that a cooperation mechanism of the family planning services and management shall be established among key regions where migrating population flow in or out, so as to promote a comprehensive control.
