Actually, the official designator is already in the books: Generation Y.
They're the people born after the last of the X'ers .... from 1981 or 1982 (better) onward, until 2001. Those born after the World Trade Center fell, are "Generation Z".
I forget which generation is the one also called "Millennials".
Yes....but there’s a group of Obama voters who are trying to get “Generation O” into the mainstream lexicon.
Google “Generation O, Obama” and you’ll see what I mean.
