For this story, 36 San Francisco Chronicle reporters spent a 24-hour period meeting members of San Francisco’s homeless community in the shelters, the streets, and on public transit to help paint a portrait of the city’s growing homelessness crisis. From the chronically homeless — those who have lived on the streets for more than a year — to young families struggling to get by in a city with skyrocketing rents, to students living in vans to get through school and military veterans seeking peace from their demons, this disparate group of people share a goal: to satisfy their basic needs for food, shelter, and safety on a consistent basis.
