While demographic profiles provide interesting reading,do not forget they are a but a snapshot in time.To be truly useful you should have at least the same info for the last ten years.Sometimes, then a" cycle" can be detected and a more educated view of the future can be determined. To draw any kind of conclusion from any form of market research is at best a dicey science.
There is and old saying "if you don't know where you have been,you don't know where you are going".
As far as Dirt track goes,what is important is that it is a thilling spectator sport and that it is great fun for the vast majority of the competitors.I would not worry too much about its future,it sits on solid ground.
