Growing by less than 40% in 100 years is slow. Austrians hardly had to scramble to provide housing for themselves.
(Now this line of reasoning is simplified quite a bit, because housing is area dependent. Even if the population in some country remains constant, say that everyone suddenly decides that a very tiny area of the country is the only worthwhile place to live. They all concentrate there and now there is a housing problem now. Well, not everywhere, just in that spot! In other spots there are empty, cheap houses.)
