I don't know... I guess I can kind of see a reasoning for some of those locations, like Iowa and Minnesota. These are places which are more rural... it may give them a good place to get used to our culture and technology without being overwhelmed by the big cities. Most of the more diverse places in the country are also the densly populated, more urban environments (in my experience). I would think that placing these refugees directly into a setting like that would be a nightmare for both the city and the people themselves.
