This article explores different problematizations of young men in masculinity research. It looks at research on young men in school, young men and sports, and young men and violence, as well as the place of young men in more general discussions about masculinity. It is argued that four main problematizations can be identified in this research, depending on whether the focus is on the structure, the group, the experience, or the categorization. Differentiating between different problematizations, it is suggested, may be a helpful way of understanding key differences in research on, as well as in interventions directed at, young men.
