I don't know. The article talks of 4,400 people, which is roughly (865,000/200=4,325) correct but references this article here: http://projects.sfchronicle.co

I don't know. The article talks of 4,400 people, which is roughly (865,000/200=4,325) correct but references this article here: http://projects.sfchronicle.com/sf-homeless/numbers/ http://projects.sfchronicle.com/sf-homeless/numbers/ where the number of people is counted/estimated as any among: 6,686 6,775 9,975 and the "curious" (I cannot understand its meaning): "Friedenbach estimates there are closer to 13,000 homeless people in the city over the course of an entire year." The 1/200 is already an extremely high ratio, but 7,000 or 10,000 would make double that at around 1/100!
