These picture charts are compiled by certain posters on the forums. While not taking away from their work, I tend to put a lot more weight on the most recent estimates, by the feds, of these families. And the estimates for New England, Philadelphia, and Chicago have all been more or less the same.

Furthermore, if the Outfit were so much bigger, as some still think (almost putting it on par with the NY families) you'd expect to see significantly more activity in Chicago than New England or Philadelphia. But you don't. The amount of indictments over the past decade are also comparable.
