Male Wota VS Female Wota

I'm using the term wota to mean any H!P fan for this. After the chat came up on H!O on this picture post, I had to use my math skills to show how many female fans there is per male.
One example I wrote at H!O:
Judging by the registered member list there is 138 pages of female members, with 20 on each, except the last one (with 2) it would equal 2,742 girls here. And 4,640 male. Lol, and 71,589 (3580 pages) members only 7,382 have specified their gender. So males are double to females registered here, with their gender set. So I can totally see why people think the female fans are almost non existent.
For every ~1.70 (yeah 3/4 a person) male fan there is one female at H!O. So if you take the Nine Smile concert final day hall seating capacity (imagine if I used the EC graduation numbers) which is 2,062. So if 2,062 gender set H!Onliners went to the Nine Smile concert only only about ~1,212 of those attendees would be female. (Coincidentally when divided equal out to 1.70, I think?) So males have a upperhand but females are around just not as many.

But if you factor in minors (as in age) I'm not sure the numbers will stay the same

Average Ratio - ~1.28 males per female

Females seem to be out numbered with the exception of MM-BBS. So many leechers!

Now to compare that to the Elder Club graduation at Yokohama arena, much like I did with Nine Smile. The capacity is 17,000, which is nothing to the 8,043 people. I will pretend I have 17k. Let's say the arena was sold out, looked like it was anyway. :P I divided by the 1.28 ratio = 13,281 males would have attended. Making it 3,719 females at that concert. Quite a huge gap!! Ratio - ~3.57 males per female.

Summary:
-It's seems males generally dominate, idols are projected to them purposely. Which can explain this.
-What can't be explained is what draws females to idols.
-The variable of children/minors can affect this.
-For every 3 and 1/2 males that attended equaled 1 female.

Hmmmmm......TBC
