In the language of my country's homeless charities, there are "rough sleepers" - people who are literally sleeping in shop doorways and on park benches - but there's a much larger number of the "hidden homeless" - people who are sleeping on an accommodating friend or family member's couch, or some other temporary arrangement like the government paying for them to stay in a bed and breakfast. Rough sleepers may well have untreated addiction and mental illness problems - there's a reason they've exhausted the patience of their loved ones - but many people among the hidden homeless have simply been priced out of the housing market.
