This really doesn't mean anything to me without a citation. Wikipedia led me to this [1] article, that states "Nearly half of the homeless money, $81.5 million, goes for rent subsidies and programs to assist the 6,355 people living in "permanent supportive housing" - long the cornerstone of the city's program for helping the down and out.".

I'm not sure if the 6,355 in the supportive housing contributes to the 7000 "homeless" statistic, but dollar spent per homeless person seems like a measurement that's at best misleading and at worst a propaganda soundbyte.
