I take it you mean "which KIND of persons". You're question is too broad and with a membership in excess of 200,000 you're going to find it difficult to answer any of your questions. Maybe the sites admin. could help you but I doubt it as not everyone uses a "name" that could be tied down to "male" or "female" or gives as much information on their bio to enable you to make a guess. Sorry to put a downer on it but IMHO you're not going to get anywhere with these questions!
