Scholars have recently revitalized labeling theory as a developmental theory of structural disadvantage. According to this approach, official intervention increases the probability of involvement in subsequent delinquency and deviance because intervention triggers exclusionary processes that have negative consequences for conventional opportunities. The theory predicts that official intervention in adolescence increases involvement in crime in early adulthood due to the negative effect of intervention on educational attainment and employment. Using panel data on urban males that span early adolescence through early adulthood, we find considerable support for this revised labeling approach. Official intervention in youth has a significant, positive effect on crime in early adulthood, and this effect is partly mediated by life chances such as educational achievement and employment.
