That, or, maybe certain types are significantly more likely to marry and settle down, which would probably affect things more currently, but didn't most people marry back in the day? If it's based on the society around us, it is possible that certain types will be more numerous according to the society in which one lives. Maybe countries which appreciate certain functions breed children who espouse these functions. Or maybe, like Howe's Generational Theory style, the children begin to pick up the slack.
But I think it's probably going to be difficult to actually find good numbers, because I'm worried about having adequate spread. I mean, potentially certain types are more likely to be bothered participating in any type of self-typing thing. I mean, online forum polls would probably suggest a greater majority of INTj's and etc.
I wish there were equal spreads of each type, that would make everything theoretically a lot more swell. Though I don't think it would give anyone a "chokehold" on distribution of information. One's success is probably more based on what functions a society values, as well as un-type-related things like intelligence, upbringing, motivation, or something like that. Potentially such types could have an advantage romantically, because their dual will suddenly realise, "You're the kind of person I've be waiting for all my life but only just found!" and would treat them like a god. But inversely it could be a disadvantage to them if there are too many from their conflicting quadra, who regard you as "different" (in the bad way) and - because they haven't had to deal types like you - think of you as a nuisance and irregular.
