Global, I guess. It has a wikipedia page: https://en.wikipedia.org/wiki/Housing_crisis

There's specific pages for some individual countries, too:

https://en.wikipedia.org/wiki/Housing_crisis_in_the_United_S...

https://en.wikipedia.org/wiki/Affordable_housing_in_Canada#A...

This one is about housing crisis, not "western homeless crisis".

At least in Europe it is not (yet?) causing very large scale of homelessness problem.

I find the name "housing crisis" misleading, because if I look at average floor area per capita, I think we should call this "expectations changed faster than buildings". For example https://doi.org/10.2908/ILC_HCMH01 (variation between 43 to 141).

I'd say it's a bit more complex as you have to deal with capital financing and a number of regulations like parking in cities that lead to issues.
