A criminological research agenda for the next millennium

This article reviews key issues in criminology concerning the development of criminal careers, risk factors or causes of offending, and effective prevention methods. In order to advance knowledge about criminal careers and risk factors, prospective longitudinal surveys are needed. In order to advance knowledge about prevention methods, randomized experiments are needed. Anew research agenda for the next millennium is recommended including (a) multiple-cohort longitudinal surveys with experimental interventions, and (b) a coordinated program of cross-national comparative research.
