These are based on the US Census American Community Survey poverty numbers. These are estimates based on the number of people living in poverty (the higher the number, the higher percentage falling into homelessness). These are based on the broader Dept of Education definition of homelessness and not the silly HUD definition of homelessness used by the shelters. These have nothing to do with the January "Complete Count" that the County and HUD release. Those numbers are mandated by Congress, but have no basis in fact. These numbers can be found for each year on our Research Section of our website under "Overall Numbers" for each year. This gives further explanation of the definition and methodology.
