And you have to think back to the turn of the 20th century, when comparing populations. Cincinnati had a much larger percentage of the population at that time than it does now. It was the 10th largest city in the US in 1900, and the 16th largest in 1920. It's hard to tell if the lack of the subway was a factor in the lower rate of growth or if the lower rate of growth meant the subway wasn't needed after all.
