Maybe it's generalized, but my first idea would also be identity and connections to culture. Perhaps more urban aboriginal people are just integrated into mainstream society and have those opportunities at hand, and have easier access to them, than aboriginal youth coming from on reserve. They might be a lot more connected with their community, they might want to stay in the community, where the same opportunities might not exist. I think that would be my first idea.
