Spiel nicht mit den Schmuddelkindern?

This study analyses the causal effect of the social composition of differently scaled socio-spatial contexts while considering different threshold values. This is made possible by elaborate and, as far as German research in this field is concerned, unique analysis of different data sources. On the one hand, the book reveals heterogeneous effects of social composition on the probability of a child attending a higher-level secondary school, and on the other hand, the added value of its methodologically complex approach becomes clear. Its results show that social composition can be understood as a factor that induces social inequalities, which highlights the relevance of taking spatial factors into account in other research subjects as well.
