The book is focused on the religiosity of a migrant group that has hardly been researched so far. Using young adults with Vietnamese roots as examples, it shows how intergenerational changes in religiosity take place in the diaspora. By means of biographical-narrative interviews with more than 20 young adults in Switzerland and Germany, the publication provides an insight into processes of identity formation, strategies of action of young adults and changed forms of religiosity. The author uses methods from qualitative social research, social network analysis and ethnography for her research.
