This paper examines the consequences of parental migratory strategies for children in three types of Mexican families: those living with their migrant parents in the United States, those living with parents who migrated and returned to Mexico, and those living in Mexico with parents who have never migrated. Using data on 804 children from the Health and Migration Survey (HMS), we found significant differences in children's health across the three types of families. Results also revealed robust effects on child health of the size of immediate and extended social networks and migration experience after controlling for potential mediators such as mother's general health, receipt of social support, and child's age and sex. Findings suggest that social networks and migration affect children in complex ways, offering health benefits to those with migrant parents in U.S. households but not to those living with parents who migrated in the past and returned to Mexico.
