Social scientists have long emphasised the importance of personal inter-ethnic contact for overcoming prejudices and enhancing social cohesion in mixed societies. But why do some people have more contact with their neighbours of other ethnicity? Using new data from a large-scale German survey, I analyse the brokering roles of children and inter-ethnic partners in explaining inter-ethnic neighbourhood acquaintances. Even on a contextual level, my results suggest that people living in regions with larger shares of children have more inter-ethnic neighbourhood acquaintances, which expands earlier findings on the general integrating function of children. However, I also argue that we should recognise brokering to be context-specific and exemplify this by showing how the brokering role of inter-ethnic partners is evident particularly in interaction with inter-ethnic encounters at local bars and restaurants, while that of children is evident particularly given their frequent inter-ethnic encounters in public parks and playgrounds. On a theoretical level, my results demonstrate the importance of studying the interaction of mechanisms in explaining personal (inter-ethnic) contact.
