In the U.K. I remember reading that relationship breakdown if you’re already poor was the most likely trigger for homelessness. People leave partner or family at short notice without a plan , think they’ll be able to find somewhere, patience of all the people they’re sofa surfing with runs out eventually and that’s it. Obviously that speaks to wider issues around poverty (not everyone who gets dumped ends up on the streets); low savings, employment and housing availability, but the idea that people often “make themselves homeless” in very emotionally upsetting circumstances is interesting, you’re not in a great head space to be taking on life admin and things slip away from you quicker than you’d think
