As the incarceration rate has exploded over the past 40 years, parental incarceration has become an increasingly common event in the lives of American children, particularly minority children and children of poorly educated parents.  Recent studies have explored the implications of parental incarceration for children’s behavioral problems, academic achievement, health, and housing stability, but no one has yet examined the social experiences of children affected by parental incarceration.  In light of previous research suggesting that the composition of adolescent social networks is important for exposing adolescents to, or insulating them from, disadvantageous peer relationships and providing social support during a critical developmental period, this paper examines the social networks of adolescents who experience parental incarceration.  Using network data from the National Longitudinal Study of Adolescent Health, I examine the relationship between parental incarceration during childhood and adolescents’ number of social ties, social location within their schools, and friend characteristics.  My results indicate that, on average, children of incarcerated parents are more socially isolated than other adolescents and have fewer friends who are more disadvantaged, less academically successful, more delinquent and less optimistic about the future than the friends of other adolescents.  These findings have important implications for the types of support programs that may be beneficial for children of incarcerated parents.
