Özet	Life-course criminology analyzes both continuity and change in offending across the entire life span, anchored in Sampson and Laub's age-graded theory of informal social control. The core claim is that social bonds that emerge at different ages — strong marriages, stable employment, military service — function as informal social control that can redirect criminal trajectories, so that change is possible at any age and is not fully determined by childhood propensity.	Group-based trajectory modeling (GBTM) is a finite-mixture method that identifies clusters of individuals who follow similar developmental paths of a behavior — most famously offending — over age or time. Introduced to criminology by Daniel Nagin and Kenneth Land in 1993, it replaces the assumption of a single average trajectory with a small number of distinct latent groups, each described by its own polynomial curve and its share of the population.
