Ratio of What

I wonder what ratio you would come up with if you took the number of people who signed up for military service and divided it by the number of people who tried out for a reality show? I wonder what that ratio would tell you if you monitored it over time or what it would actually say about the America. My assumption in posing this question is that the target audience of military service and reality show (American Idol, X Factor, Real World etc...) is probably about the same age group?
