Do a search for a study titled: Monitoring Raccoon Rabies In Alabama. My experience over the years has been that, just like coyotes, they tend to concentrate heavily where food sources are easily available. For example, the average per square mile in Southeast Alabama might be 15 or 20, but a heavily managed hunting property with feeders and year round food plots may hold 50 or 60 psm. Just like with hogs, deer feeders are a HUGE attractant.
