How the Member of Floating Family Gradually Moves to Destination, with Reference to Shanghai, China.

China’s economic development closely related to the fast increase of floating population to urban areas. Based on the 2010 national census, the proportion of floating population accounted for almost 20% in China. We take Shanghai, the largest city in China, as an example. The data come from Shanghai monitoring sampling survey conducted in May 2012. The sample covers 14993 floating people aged 15-59, whose household registration area is separated from Shanghai. The total number of the family member for the 14993 sampled objects is 44674, the average number of a floating family is 2.98. Among all family members, 37162 of them have already moved to the Shanghai, where the target object lives. The objective of this research is to disclose the structure of the floating family both in Shanghai and out of Shanghai, and how the family member gradually flows to the destination areas based on timing and ordering of their entry. Cox model for the timing will be used.
