While demographics can be a useful tool for marketing, behavioral demographics is a slippery slope. First mistake junior markeeters make is assuming that if someone is a member of a particular group, they will behave like the group. It's statistics 101. 50% of the population has below average intellegence for instance.
The second mistake is extended assumptions. Usually our data is not granular enough to make sweeping assertions based on combining several statistics.
What brought this to mind, was seeing War in Salt Lake. (reminded me of going to Foster Beach in the summertime growing up.) I got into a discussion with one of the concert promoters. It's a delicate equation. They need to balance the cost of the perfomer, overhead and venue against ticket price and sales. Every band appeals to different people.
