The relationship between rural to urban migration and child growth and family structure is reported in a sample of 302 children from families of low socioeconomic status, living in Guatemala City. The sample was divided into three groups: 1) children of parents born outside the city, 2) children of parents born in the city, and 3) children with one migrant and one city-born parent. Children of migrants to the city were the smallest and significantly shorter than children of migrant city-born parents. Migrant parents also had the largest families; family size correlated negatively with growth in height. Growth in weight followed a pattern similar to height, but no significant differences associated with migration status were found between groups.
