Developmental criminology quantifies dynamic concepts for capturing importa
nt ingredients of change and stability. It distinguishes between continuity
and stability and thereby recognizes that manifestations of deviancy in th
e course of individuals' lives may change, while the underlying propensity
for deviancy may remain stable. It considers the course of offending in oth
er developmental contexts, such as life transitions and developmental covar
iates, which may mediate the developmental course of offending. It aims at
generating new knowledge about the etiology and precursors of offending, wh
ich may be relevant for much-needed improvements in future prevention and i
ntervention programs. Activation, aggravation, and desistance are the three
primary developmental processes of offending. Developmental criminology po
ses new questions and therefore encourages innovation in analytic methods t
hat may help to describe and explain longitudinal changes in individuals' o
ffending. These processes do not occur merely as a function of individuals'
chronological age. It is important to search for variables that determine
or mediate the variation of behavior with age. It is possible to operationa
lize individuals' positions within a sequence, distinguishing between indiv
iduals' qualitative and quantitative changes in offending.
