Analyzing data from "2010 Survey of Children Development in Beijing",schools attended by migrant children can be divided into three types,namely schools of exclusively migrant children,public schools attended by many migrant children and the public schools attended by few migrant children.Migrant children attending different types of schools generally come from different social strata of floating population.There are increasing trends in socio-economic levels,quality of social networks,proportions of only child,and family education expectations and conditions across the three types of schools.No significant differences exist in either school performances or family conditions between migrant and local children in public school attended by few migrant children.
