I always though like in most societies the numbers are relatively equal. It would be hard for a group to have more of one gender because there is a 50% change of a male or female to be born meaning that it is mostly equal. Unless something happened and a good portion of the male population is killed off. In my opinion, I just believe that most of the males are off doing work for most of the day (Big Mac, and the royal guards for example), Female are more prominent because they have the time to go do things that the males just can't so they show up on camera more often...
