Some interesting stats in there.
I know it doesn't reflect all of trans* people everywhere but I found that state that the mtf to ftm ration is 60/40. I had noticed awhile back there just seemed to be more mtf's than ftm's.
13% of respondents listed, "a gender not listed here" when asked what their primary gender identity was today.
21% (the 2nd highest listed) identified as gay/lesbian/same gender and 23% (the highest listed) were bisexual.
The differences between "people can tell I'm transgender even if I don't tell them" where vast between mtf and ftm but honestly I still think a segment society is more anti male to female. If you've got an F on your birth certificate it's a lot more accepted (even by those who would discriminate against an mtf) for you to have male mannerisms, look more male ("tom boy", etc.), dress more male, participate in what could be traditionally defined as male activities, etc.
This one was interesting too, "18% of respondents that identified as transgender did not want to "live in a gender other than assigned at birth".
