Indians/pakistanis tend to live together in areas where you wouldn't see them unless you went there, then they obviously have to go to their local town for the shops/bank etc which is the only other time you might see them. Black people do seem to mix in a but more slightly in terms of where you live, like you are more likely to have a black person living on your street than having an indian/pakistani family on your street. Pakistanis are either non existent in an area or have taken over the area, they don't mix in with us and from what I have seen they don't want to either.
More on topic, when they have black people on TV I think that is to help us get use to living with them but when they have these massive indian/pakistani families I think that is purely so they don't feel left out and start complaining about it.
