Non-white people are also overrepresented in homeless populations, with such groups two and one-half times more likely to be homeless in the U.S. The median age of homeless people is approximately 35. Statistics for developed countries
In 2005, an estimated 100 million people worldwide were homeless. The following statistics indicate the approximate average number of homeless people at any one time. Each country has a different approach to counting homeless people, and estimates of homelessness made by different organizations vary wildly, so comparisons should be made with caution. European Union: 3,000,000 (UN-HABITAT 2004)
England: 11,580 single households were assessed as rough sleeping at the point of approach in 2021, up 39% from 2019–20, with 119,400 households owed a prevention duty in 2020–21 
Scotland: 27,571 households were assessed as homeless in 2020/21, a decrease of 13% compared to 2019/20 
Canada: 150,000
Australia: On census night in 2006 there were 105,000 people homeless across Australia, an increase from the 99,900 Australians who were counted as homeless in the 2001 census 
United States: The HUD 2018 Annual Homeless Assessment Report (AHAR) to Congress reports that in a single night, roughly 553,000 people were experiencing homelessness in the United States. According to HUDs July 2010 fifth Homeless Assessment Report to Congress, in a single night in January 2010, single-point analysis reported to HUD showed 649,917 people experiencing homelessness. This number had increased from January 2009s 643,067. The unsheltered count increased by 2.8 percent while the sheltered count remained the same.
Also, HUD reported the number of chronically homeless people (persons with severe disabilities and long homeless histories) decreased one percent between 2009 and 2010, from 110,917 to 109,812. Since 2007 this number had decreased by 11 percent. This was mostly due to the expansion of permanent supportive housing programs.The change in numbers has occurred due to the prevalence of homelessness in local communities rather than other changes. According to HUDs July 2010 Homeless Assessment Report to Congress, more than 1.59 million people spent at least one night in an emergency shelter or transitional housing program during the 2010 reporting period, a 2.2 percent increase from 2009. Most users of homeless shelters used only an emergency shelter, while 17 percent used only transitional housing, and less than 5 percent used both during the reporting period. Since 2007, the annual number of those using homeless shelters in cities has decreased from 1.22 million to 1.02 million, a 17 percent decrease. The number of persons using homeless shelters in suburban and rural areas increased 57 percent, from 367,000 to 576,000. In the U.S., the federal governments HUD agency has required federally-funded organizations to use a computer tracking system for homeless people and their statistics, called HMIS (Homeless Management Information System). There has been some opposition to this kind of tracking by privacy advocacy groups, such as EPIC.However, HUD considers its reporting techniques to be reasonably accurate for homeless in shelters and programs in its Annual Homeless Assessment Report to Congress.
