In this chapter I review the social psychological underpinnings of identity, emphasizing social cognitive and symbolic interactionist perspectives and research, and I turn then to key themes of current work on identity–social psychological, sociological, and interdisciplinary. I emphasize the social bases of identity, particularly identities based on ethnicity, race, sexuality, gender, class, age, and (dis)ability, both separately and as they intersect. I also take up identities based on space, both geographic and virtual. I discuss struggles over identities, organized by social inequalities, nationalisms, and social movements. I conclude by discussing postmodernist conceptions of identities as fluid, multidimensional, personalized social constructions that reflect sociohistorical contexts, approaches remarkably consistent with recent empirical social psychological research, and I argue explicitly for a politicized social psychology of identities that brings together the structures of everyday lives and the sociocultural realities in which those lives are lived.
