Los Angeles County now has an interactive map allowing you to view the distribution of the County's current homeless population, as well as sites where shelter or supportive housing already exists or is under development. Info on population numbers and density is drawn from the January 2019 Countywide Homeless Count. New info and capabilities will continue to be added to this map tool, which just launched Dec 12.
