A blogger spent a morning on the NYC subway, making simple demographic notes on who rides, when — fascinating stuff:
3:00-4:00 AM:
Drunks of all sorts, club kids, and winos. Late night workers, busboys, getting off their shifts. Only a handful of people per car. 6:1 male/female ratio.4:00-5:00 AM:
Transit workers changing shifts. Maybe 6 people per car. All male.5:00 AM – 6:00 AM:
Blue-collar laborers, minorities, immigrants. Half the car is asleep. Maybe 20 or 25 people per car. 9:1 male/female ratio.6:00 AM – 7:00 AM:
Construction workers, blue-collar laborers, hospital workers. 75% of seats in car are taken. 7:3 male/female ratio.
