If I might, one thing I want to point out is that these types of subjects are precisely the subject matter of much of the research in social science today. I would refer you to Professor David Wolfe, from the University of Toronto, who has done extensive work on clusters and hubs.
This research is generally available and the international examples are clear, so the questions are these: can we access it; how do we need to access it; and what can we learn from that? It is available.
