Bourdieu’s key conceptual tools, including the forms of capital and habitus, have recently come to be deployed with greater frequency in criminological research. Less attention has been paid to the concept of the field, which plays a crucial role in Bourdieu’s vision of how the social world operates. We develop the concept of the "street field" as a tool for scholars of crime and deviance. The concept serves as a guide for research and an instrument of vigilance, drawing attention to the agonistic nature of social relations and the role of domination, the importance of contextual factors in shaping the objects we study, the skillfulness of agents, and the transformative effects of remaining within semi-enclosed domains of social action over extended periods of time.
