I personally think it's moreso younger ages. Yeah, people have been posting that they know more people in their teens and twenties playing, but this is a forum. Most six through ten year olds aren't on forums, at least not more... well, professional forums, like pokecommunity. So, I think that while the people we know who play Pokemon, and we ourselves, might be like thirteen through twenty-five and even higher, the majority of the kids who are drawn into Pokemon games seem to be the younger generation who got hooked at either the releases of R/S/E or D/P.
