Portrayal of Copenhagen's Middle Eastern community

I noticed that in this film there were no characters of Native Danish decent. It seemed that the middle eastern community shown lived in a kind of isolation.

The film showed that these indiviuals lived in the city of Copenhagen and yet were so isolated from the rest of Danish society. I did notice when I was there last year, that there is a large middle eastern population within this city. I really wonder if this ethnic community is really as isolated as shown in this film..
