Membership categorization analysis (MCA) is a tradition of qualitative empirical research focused on the understanding of membership categories as they are used by people in talk and social interaction as well as in texts and other media of communication. Membership categories refer to identities, and MCA is focused on the study of identities as they are achieved or contested, organized, and understood within the practical contexts of social interaction and language use.
