Western European countries do careful planning of which municipalities get how many of which migrants - it just turns out that people tend to move where their family and friends from their home countries are. This is how ghettoization actually happens at scale, same story with Czechs and Poles in the US back in the day. You can't mandate that i.e. a Moroccan family cannot live within a mile of another, that would be crazy.
