In this study, we use population-based linked administrative data to document the full child protective service (CPS) histories of arrested youth and young adults. We extracted records for all individuals aged 24 and under who were arrested in California in 2014 and 2015. These records were probabilistically linked to statewide CPS records dating back to 1998. Overall, 43.4% of those arrested had a history of CPS involvement. Among individuals with uncensored CPS records (born in 1998 or later), 60.2% had past CPS involvement. Findings indicate that youth and young adults booked for a felony offense were more likely to have a history of CPS involvement than those booked for misdemeanors. A multinomial model served to confirm bivariate findings. This study provides further evidence that community concerns of childhood maltreatment were common among criminal justice-involved young adults.
