Frontiers in Developmental and Life-Course Criminology advances the field of developmental and life-course criminology (DLC) by highlighting some recent methodological innovations, and exploring the ways in which DLC criminologists are helping to bridge the gap between science and service by their engagement with policymakers and government and non-government agencies. The book is united by three related themes: the use of new data sources including government administrative data systems, the development of intervention and prevention strategies grounded in DLC research, and resilience, prosocial behaviour, and strengths-based approaches. This book opens up new possibilities for the future of DLC research, orienting the DLC field as one that prioritises the achievement of better outcomes for individuals and society.
