Arranged marriages are common in countries like Turkey, but almost non-existent in the Western European destination contexts of Turkish migrants. For a better understanding of marital change in migration, this paper maps the prevalence of arranged marriages versus couple-initiated marriages among Turkish migrant families in Europe and stayer families in Turkey. The paper applies the ‘dissimilation perspective’ with a focus on change across marriage cohorts and between family generations. The database used for this study is the 2000 Families study (conducted from 2010 to 2012), which includes three-generational data of migrant and stayer families from five regions of origin in Turkey. Findings suggest a high similarity between migrants and stayers in terms of a strong decline of the arranged marriage mode over time, from well over 80% to about a third of all marriages. At the same time, the percentage of arranged marriages is lower among migrants. The three-generational data suggest multiple patterns of intergenerational change between grandparents, parents and children, both from couple-initiated to arranged marriages and vice versa. Overall, intergenerational transmission is stronger in stayer and weaker in migrant families. This contributes, together with lower starting levels among migrants, to the lower shares of arranged marriages among migrant children.
