How are "homeless" defined in different countries? There was an eye-opening 99pi series of podcasts around homelessness in USA where I learned that the definition is ridiculously strict.
Something like "If you slept anywhere other than the street last night, you do not qualify as homeless". I can't remember if tents count, but sleeping on a friend's couch, squatting a derelict building, or staying in your car disqualifies you from the definition of homeless.
That definition is not necessarily applicable to actual research studies, homeless counts, or even government programs. You have to look to the actual study or program details. Unfortunately, the applied definition is rarely reported in the media.
One study I saw of the local schools that breathlessly reported huge homeless rates of schoolchildren counted every child that didn't have a dedicated bedroom. Sleeping on Dad's couch? Homeless.
