This is a collection of original research reports on the status of street gangs and problematic youth groups in Europe, as well as a set of reports on the current status of American street gang research and its implications for the European gang situation. Seven American papers are joined with reports from England, Norway, Sweden, Denmark, Germany, Russia, Holland, Belgium, France, and Slovenia. Summary chapters by the American and European editors provide overviews of the street gang picture: the associated issues and problems of definition, community context, comparative research procedures, and implications for prevention and intervention. Professionals and students will find these papers easy to comprehend yet fully informative on comparative street gang studies.

Background In July of 1992, approximately sixty scholars and researchers met for a week at the "Fritz Erler Akademie" in Freudenstadt, Germany, to participate in a workshop entitled "Cross-National Lon gitudinal Research on Human Development and Criminal Behavior." The participants represented 15 nations and 45 universities and research centers. Although longitudinal research in criminology has a long history, this workshop represented the first one in the field of criminology in which it was attempted to get together the main scholars in this field from around the world. The largest group of the workshop represented American scholars (19), a reflection of the fact that longitudi nal research in criminology is predominantly conducted in North America. This volume is the result of the workshop process and in particular of the invitations to participants to prepare pre or conference papers. The chapters in this volume were selected from a larger set of pre- or conference papers. As workshop conveners and volume editors, it falls to us to set some of the context for this enter prise. Longitudinal research in criminology became a major approach after the publication of the land mark study by Wolfgang, Figlio, and Sellin "Delinquency in a Birth Cohort" in 1972. Around the same time, when Wolfgang, Figlio, and Sellin started their Philadelphia cohort study, were longi tudinal studies, although different in scope and aim, launched by Shannon in the USA, West in England, Janson in Sweden, and Goppinger in Germany."
