Researchers have examined aspects of gangs and their members for almost a century. This work, however, focuses primarily on youth prior to joining as well as during gang involvement. While comparatively less is known about the leaving processes, work in this area has been increasing in recent years. This chapter will discuss the growing body of research on the processes associated with leaving the gang. Specifically, it will review difficulties associated with defining gang desistance, theoretical perspectives on desistance, variations in motives, methods, and consequences of leaving, barriers to desistance, as well as make recommendations for policy and future research.
