Аннотация:The intersubjective dialogic exercise through which identities and knowledge are constructed exists in a dialectic relation with the ‘place’ of the interview. The in situ nature of interviewing should not be overlooked. Two case studies of interviews conducted with older people in Britain about their social network and support are used to illuminate two aspects of the socio‐spatial construction of interview data. First, interview sites can yield important information about the way participants construct their individual and social identities. Second, such identities can influence interviewer–interviewee dynamics.
