In this study we investigate organized crime by studying the degree of criminal organization. We use population-level register data on criminal suspicions between 2011 and 2016 to analyze the territoriality of Swedish street gangs in terms of geographical mobility, their collaboration in crime through their co-offending network's clustering and community structure, and their crime versatility. Although Swedish street gangs exhibit varying degrees of geographical mobility and criminal collaboration, overall, they have limited reach along these dimensions, characterized by low clustering and limited crime specialization. Violence seems to become a necessary tool only when a gang reaches a certain degree of organization. By unbraiding criminal mobility and its association with other organizational elements such as criminal collaboration in different settings, we provide insights into the structure and dynamics of criminal organizations and contribute to a richer understanding and conceptualization of how crime is organized.
