Yes, people often consider that, and then they look at the data: http://sfgov.org/lhcb/sites/sfgov.org.lhcb/files/2015%20San%20Francisco%20Homeless%20Count%20%20Report_0.pdf http://sfgov.org/lhcb/sites/sfgov.org.lhcb/files/2015%20San%... 70% of homeless people in San Francisco were housed residents of San Francisco before the became homeless, and most of the remaining 30% were in a city adjacent to San Francisco before coming to SF after becoming homeless. Also, the idea that social services are "widely available" to homless people in San Francisco is a farce. For example, there is only 1 available shelter bed for every 5 homeless people.
