Ok fine I went and calculated the aggregate numbers and indeed the homelessness per capita in Europe (EU) is higher than the US

EU:

1.1 million homeless people https://www.feantsa.org/files/Themes/Overview/2025/ex_summar...

Divided by a population of 451,990,314 https://en.wikipedia.org/wiki/Demographics_of_the_European_U...

= 0.00243

US:

745,652 homeless people https://www.huduser.gov/portal/sites/default/files/pdf/2025-...

Divided by a population of 341,784,857 https://en.wikipedia.org/wiki/Demographics_of_the_United_Sta...

= 0.00218
