Well yes, CMA does a great job of doing the statistics every year. And they are free for everyone to make something of. Here's the one for 2008 http://www.cmaworld.com/media/pdf/marketing/2008_cma_industry_overview.pdf

Statistics can be useful, if you are really good at reading them. But if you think you can make something out of statistics without a particular emphasis, you can forget it. As a songwriter mailnly in country and adult contemporary (well, I do drift some also), these stats are useful as a broad framework for knowing the target audience. I can use it to interpret which point of view's will be commercially viable, and decide which images and values that will most probably be commercially viable to include in my writing. So the demographics can at best help me to better the odds of getting a cut, knowing and acting on some of these things.

But when that is said, I don't think a lot about them in the creative process. When I listen to your songs on your Myspace site, they more comes across as folk/rock, and the closest commercial reference that comes to mind is Bruce Springsteen.

If that premise is accepted, then you might ask, but what are the demographics for that? I'd say the male counterparts of the country stats. Male listeners between 30-50, just about..
