Homelessness solution must address health as well as housing

California has the unfortunate distinction of having the largest homeless population of any state in our country. On any given night, 20 percent of our nation’s homeless are on California’s streets or in our shelters. Anyone who strolls down our city’s streets can witness San Francisco’s homelessness crisis. Despite years of effort and billions of dollars, we have nearly 7,000 homeless residents in our city, which should not be the case for one of our nation’s most progressive, innovative and wealthy cities.
