A configurational approach to transnational families: Who and where is one's family in the case of mobile older adults?

<jats:title>Abstract</jats:title><jats:p>This article introduces a novel transnational family configuration (TNFC) approach to study the diversity of family forms across kinship and geographical boundaries. Integrating theoretical insights from family sociology and transnational family research, it examines contemporary families as personal networks that encompass both subjectively identified and potentially transnationally dispersed kin and non‐kin members. Drawing on original survey data and in‐depth interviews with adults aged 55+ living in Switzerland, it compares migrants’ and non‐migrants’ personal family networks. The results indicate that these networks are both diverse and transnational. Although there is a strong correlation between transnationality and migration background, other life‐course factors also contribute to the development of transnational family networks beyond the scope of migrant ‘exceptionalism’. By advocating the adoption of a TNFC approach to the study of contemporary families, in diverse population groups and various cultural contexts, this study paves the way for future research in this area.</jats:p>
