Using Pierre Bourdieu's theories of social class differentiation and class reproduction, this paper provides an analysis of class-based identity politics in contemporary suburban America. Through a critical ethnography of the emergent, American, upper-middle-class "soccer mom" phenomenon, this study contributes to a growing body of research that interrogates class-based, cultural practices of status differentiation. As part of a larger, longitudinal ethnographic study, this paper specifically focuses on the ways in which women, who are driven by upper-middle-class habitus, contest and construct their identity as mothers of young, soccer-playing children.
