Source: Duan Chengrong et al., estimation based on the 2000 and 2010 Population Censuses, and the 2005 One Per cent Population Sample Survey conducted by the National Bureau of Statistics.
The number of migrant children and left-behind children increased significantly in 2010, compared to 2000 and 2005. While the number of migrant children increased more rapidly between 2005 and 2010, the number of left-behind children was more stable. This reflects the current shift in the tendency of migrants "moving with spouses" to the pattern of "moving with spouses and children". A continuation of this trend implies that the number of migrant children in China will continue to increase in the future.
