I don't think that's necessary to refute the original point. The point I was disagreeing with was that automatic doors have "won" and doormen are no longer relevant. Whether 25,000 is a higher proportion of New Yorkers now than it was in 1930 isn't really a key point. 25,000 remains a large enough number that it is not true that doormen have been wiped out.

That said, to your actual points, as an intellectual exercise: while the population of New York has increased since 1930 (from around 7m to around 9m), the number of doormen has gone up much much faster (from "a few thousand" according to NPR to 25,000). So on the criteria you listed there, the number of doormen has increased as well.

The doorman example remains true.
