Considerable numbers of individuals are first-time convicted for offenses committed at age 25 or later; adult-onset offending is relatively more prevalent among females than among males

Highlights
•    The current study uses prospective population-based longitudinal conviction data.
•    Considerable numbers of individuals are first-time convicted for offenses committed at age 25 or later.
•    Adult-onset offending is relatively more prevalent among females than among males.
•    Adult-onset females account for a substantial share of all female adulthood convictions.

Abstract

Purpose: The current study explores male and female adult-onset offending careers in a Swedish population-based longitudinal dataset comprising five successive birth cohorts which are followed prospectively on the basis of detailed conviction data to age 50.

Methods: Adult-onset offenders are compared to juvenile-onset offenders on a number of criminal career measures. Growth curve analysis is employed to visualize average trajectories for convictions during adulthood.

Results: The study found that 22% of convicted males and 38% of convicted females were convicted for the first time for offenses committed between ages 25 and 50. The adult-onset males contributed 19% of all male adulthood convictions and 16% of male violent convictions in adulthood. The adult-onset females contributed 47% of all female adulthood convictions and 48% of female violent convictions in adulthood. While the adolescent-onset trajectories displayed generally decreasing trends for offending in adulthood, adult-onset females displayed increasing trends in relation to trajectories of violence and drug/alcohol-related offending as they approached middle adulthood.

Conclusions: There is a need for developmental and life-course theories of crime to be explicit in explaining adult-onset offending, particularly in relation to gender disparities.
