I've always wondered about the Rush Limbaugh demographic, and while I'm still looking for relatively unbiased radio statistics (there is a Vanity Fair article out there, but I'm not sure it's all that credible), I did find some stats for his website from what appears to be a credible source:
Over Age Age 35 (79%)...with the majority of that being over age 50
Has No Kids (76%)...most likely because the kids have grown & moved out
Earns More Than $60k/Year (67%)...with the majority earning over $100k/year
Attended College/Grad School (80%)
Bottom Line: (not so shockingly) older white people.
I'll keep looking for the radio demographic, but I do have a few ideas as to what I'll find...
...it will be as white
...it will be even more male
...it will be even wealthier
...it will be older (maybe much older; Vanity Fair claims an average listener age of 67)
