Gender Ratios

So MMO Champion has been working on a lot of stats lately and the first they have released is the Gender Ratio numbers. Now this is for level 85 characters and some of the results are very surprising to me. Look at the numbers here for the races male to female

Human 66.48% 33.52%

Orc 89.34% 10.66%
Dwarf 86.72% 13.28%
Night Elf 56.2% 43.8%
Undead 77.4% 22.6%
Tauren 85.82% 14.18%
Gnome 69.43% 30.57%
Troll 74.24% 25.76%
Goblin 72.44% 27.56%
Blood Elf 55.05% 44.95%
Draenei 47.73% 52.27%
Worgen 80% 20%

Looking at these numbers some things are rather surprising. One being that dwarf female is not the lowest as it has been stated for years that this is the least played race and gender. What it probably relates to is the fact that more people play orcs than dwarves so the percentage of female dwarves is actually higher. I really think the Blood Elf and Night Elf numbers must be skewed some how. There really is more males than females? Have I been playing on the wrong server to actually change my thoughts on this? I can understand why Draenei Female is higher for the fact that male casting animations and the way their tail design works can be bothersome. Also I always thought there was many more female Undeads, maybe this is because the number of male Undead rogues that I have been unable to see because they must be stealth all the time.

So what is everyone's thoughts on this? Think the way I do or do you completely believe this?
