Which factor contributes to special education placement of students from culturally diverse backgrounds?

Different educational placement of student with culturally diverse backgrounds is a manner of segregation, in opposition to current trend in eduation models that foster universal integration instead.

The model of urbanization is a factor that contributes to these new forms of segregation. Children usually attend the public school which is the closest to their home. If cities are structured in such a way, that people from different cultural backgrounds tend to live in different neighbourhoods, their children will also attend different schools.
