Fewer people than 100 years ago, compare that to Bay Area. https://en.wikipedia.org/wiki/Vienna#Demographics

100 years ago there were 4 families in the now single apartment I live in. There was an extreme housing crisis and the current system started then as a direct response to that extreme overcrowding.

Bay Area could learn a lot from Vienna. Especially about building up.
