This article surveys recent work on the idea of "citizenship", not as a legal category, but as a normative ideal of membership and participation. We focus on two emerging issues. First, whereas traditional notions of citizenship assume that membership and participation are promoted by the possession of rights, many theorists now emphasize civic responsibilities. Second, whereas traditional theories assume that citizenship provides a common status and identity, some theorists now argue that the distinctive needs and identities of certain groups -such (...) as women, ethnic minorities, the disabled - can only be accommodated through "group-differentiated citizenship". The writings of neo-conservatives, participatory democrats, civic republicans, feminists, civil society theorists, virtue theorists and cultural pluralists are surveyed. (shrink)
