This actually reminds me of MLP:FiM, there was a long running fan theory that Ponyville took place in a gated lesbian community due to there only being five males present in town for the longest time while everyone else was female. (Mr. Cake, Big Macintosh, Snips, Snails, and Spike.)

I think they started doing more equal gender representation in crowd shots after awhile if memory serves, but it's been awhile.
