Homeless:

FWIW, FEANTSA estimated over 1.2MM homeless in Europe in their most recent report[1]. That's over a population of 515MM so ~23 per 10k population. Us 746k homeless is roughly 22 per 10k population. I suspect that differences in methodology will overwhelm that 1/10k difference, but the order of magnitude seems similar.

1/3 of the US homeless are unsheltered ("Living Rough" in the FEANTSA terminology). A quick skim of the FEANTSA report did not show any countries breaking out their rough-sleepers from the rest of the data. I do suspect that this number is higher than in the EU.
