During successive ethnographic studies, based at the University of Warwick, children and young people have articulated their religious identities. This article reflects retrospectively on elements in the identity formation of children and young people from a range of ethnic and faith backgrounds. With particular reference to religion, but also noting other aspects such as ethnicity and caste, this article examines the children’s and young people’s disclosures of their identities and whether they are discovering or constructing them. Their articulations of identity suggest changes and continuities for individuals during their school years, as well as similarities and divergences between the experience of individuals from diverse backgrounds and over several decades. They reveal the situational and interactive aspect of identity and of self-differentiation from ‘others’, the contribution of family members, supplementary classes, school (teachers and peers), of technology and of the researcher. The research interview, it is suggested, both facilitates young people’s articulation of their identity and exemplifies the encounter-based narrations that cumulatively constitute identity.
