The Los Angeles region is thought to have the largest concentration of homeless persons in the country. In its biannual census of 2005, the County counted nearly 90,000 homeless persons living in the county at any given night. A quarter of a million are expected to be homeless at any time of the year. A 50-block area in downtown Los Angeles called Skid Row has a homeless population as large as the homeless population of San Francisco. Hollywood and the city of Santa Monica also suffer from visible homelessness. To combat homelessness, public and private service providers launched a new initiative called Bring LA Home, a program that would build 50,000 housing units for homeless persons and end homelessness within 10 years.
