I'm 19 and from northern Ohio. I say "on accident" and so do most of my friends. I asked Dad (who's 42) what he says, and he replied "why don't you just say that he accidently broke the vase?" laugh I told him that his answer wouldn't work and that this was for a poll, and he said "well, I'd say on accident." Then I thought that maybe it's a northern Ohio thing. Mom came downstairs shortly after that and I asked her. She said "oh it's definitely by accident." But, she studied English in college so she always speaks correctly smile Well, that's just my two cents.
