most of these are legal immigrants, so the country decided to accept them, and yet failed to build enough to keep up with demand that they allowed.

I agree that both things are caused by one level or government or another. I'm just saying that under building is not the only explanation. It's probably not even the most natural one. It's maybe a second or effect once you've decided to admit multiple cities' worth of people each year.

Curious, what happened to their previous homes ? Did they become Airbnb rentals on the cheap too by any chance ?

[robertlagrant]

That would be an odd thing to assume. Net immigration has long predated AirBnB.

Obviously I wonder about post-AirBnB migrants... or maybe also can we see changes in the source countries between pre- and post- ?
