This study analyzed the relation between the friendship networks of parents and the peer networks of their children. Subjects were 255 second- through fifth-grade children of an inner-city primary school in the western part of Berlin, Germany, who were interviewed about friends. In the interview, children were asked to name other children with whom they shared activities outside school. In the second phase of data collection, a subsample, composed of the parents of 116 children, were interviewed separately at home about their social networks. Analysis revealed that the number of mothers' and fathers' leisure-time friends was positively related to the number of the children's peer relationships with non-classmates, but not with classmates. In the case of fathers, the relation was similar for sons and daughters. For mothers, the relation depended on their employment status: for mothers employed full time, the number of leisure-time friends correlated positively with the number of peer relationships of girls, but negatively with the number of peer relationships of boys. For mothers who were not employed full time, the number of leisure-time friends was positively related to their sons' and daughters' peer relationships with non-classmates.
