It will be interesting to see these numbers over time to tell how much of this is people being more open due to less fear of judgement, compared to how much of this is a fad and younger people seeking to identify as something to fit in with their peer group, or to have an easy in to a peer group.

With bi making up 50%, that seems like an easy in to the group, gives the person some political power, and they really don’t need to do anything different than what they were doing before. I’d be curious to see the gender breakdown on the bi category, I have some assumptions on what is happening there.
