Feeling unsafe in a multicultural neighbourhood has been related—especially in the case of indigenous inhabitants—to the presence of groups of young immigrant men in public space. However, indigenous inhabitants differ in their response to the presence of immigrant men. Our goal is to examine (in a qualitative and quantitative way) whether interethnic social involvement has added value when it comes to explaining the experience of fear of crime, as compared to general social involvement. We conclude that our thesis regarding the relevance of interethnic social involvement for explaining the experience of safety is sustained by our material. Therefore, we advise that interethnic social involvement should be integrated in future studies on the fear of crime.
