The Company You Keep: Adolescent Mobility and Peer Behavior*

Abstract

Residential mobility has been linked to a variety of problematic behaviors during adolescence, but the reasons for this association are not well understood. This analysis examines the relationship between adolescent residential mobility and the academic and deviant behaviors of members of adolescents’ friendship networks. Using data from approximately 12,000 respondents in the National Longitudinal Study of Adolescent Health (Add Health), we find that residentially mobile adolescents belong to school-based friendship networks whose members exhibit weaker academic performance and expectations, less school engagement, and higher rates of deviance than do members of the friendship networks of nonmobile adolescents, even after controlling for adolescents’ own academic and deviant behaviors. These differences in the behavioral composition of adolescent friendship networks are not ephemeral, but appear to persist for several years. Moreover, these differences are equally pronounced among older and younger adolescents and among girls and boys. We also find that parental socioeconomic status is positively associated with adolescents’ involvement in high-achieving and prosocial friendship networks. Directions for future research exploring the impact of residential and school mobility on adolescent development and functioning are discussed.
