Abstract:Using an individual-level dataset drawn from the China Health and Nutrition Survey in 2000, 2004, 2006, and 2009, this paper investigated whether the parental labour migration is associated with defi ciencies in the nutrition intakes of children left at home in the rural area. Th e results show that the parental migration increases the probability of deficiency in the energy and protein intake of children left at home. Although several studies have pointed out that the parental remittances can increase the economic well-being of their children at home, this study points to an undesired cost of the parental migration. Governments should establish eff ective policies to promote the benefi ts of migration while minimizing the potential costs. In particular, specifi c social welfare programs targeting on children in the rural area can be designed to insecure the nutritional health of children left at home in the rural area.
