Relationship breakdown most common reason for homelessness

Thanks to Bob McCoskrie who sent me this Australian research which finds that relationship breakdown is  the most prolific cause of homelessness. While public perception is that drug taking is the major cause, when people who have actually experienced homelessness are asked, the reasons given are quite different:

"....this research ... shows that people who have experienced homelessness have a more reliable sense of why they found themselves in that situation than the general public.
They cited ‘relationship breakdown and conflict’ as the main cause for homelessness six times more often than substance use (64 per cent vs 10 per cent). In contrast the general public cites ‘marriage or relationship breakdown’ as being the main cause for homelessness less often than that of substance use."

(Naturally public perceptions and research findings are predicated on the definition of homelessness.)
