Previous research has shown a robust association between different childhood and adolescent vulnerabilities and youth offending. However, these investigations have primarily focused on youths from high-income Western countries. Consequently, the generalizability of these findings to better inform global justice policies remains uncertain. This study aimed to address this gap by examining the relationship between individual, familial, and contextual vulnerabilities and criminal versatility during young adulthood, accounting for sociodemographic factors and cross-national differences. Data were derived from a diverse sample of 4,182 young adults. Results indicate that child maltreatment, substance abuse, and delinquent peers are global risk factors for criminal variety. Moreover, they are independent among males and females and youths living in countries ranked
differently on the Human Development Index (HDI). In addition, some childhood vulnerabilities showed different predictive ability across sexes (e.g., school failure), and across countries ranked differently on the HDI (e.g., family dysfunction).
