AbstractIntroductionThere is abundant literature about the benefits of social capital in youth, but less is known of the origins of social capital. This study explores whether adolescents' social capital is shaped by their parents' social capital, their family's socioeconomic status (SES), and the socioeconomic profile of their neighborhood.MethodsThe study uses cross‐sectional survey data gathered from 12 to 13‐year‐old adolescents and their parents (n = 163) in Southwest Finland. For the analysis, adolescents' social capital was disaggregated into four dimensions: social networks, social trust, tendency to receive help, and tendency to provide help. Parents' social capital was measured both directly (parents' self‐reports) and indirectly (adolescents' perceptions of their parents' sociability). The associations with the hypothesized predictors were analyzed using structural equation modeling.ResultsThe results suggest that social capital is not directly intergenerationally transmissible the way some biologically heritable traits are. Yet, parents' social capital shapes youngsters' perception of their sociability, and that, in turn, predicts each dimension of adolescents' social capital. Family SES is positively related to young people's reciprocal tendency, but the pathway flows indirectly through parents' social capital and adolescents' perception of parents' sociability. Conversely, a disadvantaged socioeconomic neighborhood is directly negatively associated with adolescents' social trust and tendency to receive help.ConclusionsThis study suggests that, in the studied Finnish, relatively egalitarian context, social capital is (at least partly) transmissible from parents to children, not directly, but indirectly through the mechanism of social learning.
