Definition
Developmental criminology asks how criminal behaviour unfolds over a person's life — when and why offending begins (onset), why it continues (persistence), and what causes it to stop (desistance). It treats the offender's trajectory, not the discrete offence, as the unit of analysis, and links each phase to risk factors at the individual, family, peer, and neighbourhood levels.
The tradition crystallised in the 1990s through David Farrington's Cambridge Study in Delinquent Development and Terrie Moffitt's distinction between adolescence-limited and life-course-persistent offenders. Both showed that early-onset offending, combined with childhood adversity, predicts longer and more serious criminal careers, while most adolescent offending fades without intervention.
Why it matters
How it works
Developmental criminologists track cohorts over decades, recording offending alongside family, school, and peer variables. Patterns emerge: poor parental supervision, low impulse control, antisocial peers, and concentrated neighbourhood disadvantage predict earlier onset and longer careers. The framework supports targeted prevention — parenting programmes, early-years education, mentoring — aimed at altering trajectories before they harden.
The model has limits. It can drift toward biological determinism if risk factors are read as fixed traits, and it understates how policing and labelling produce the very persistence it measures. Critics from labelling and critical criminology argue that the system reacts more harshly to early-onset cases, making the "life-course-persistent" category partly an artefact of social reaction.
