An Estimated 2% of the World's Population (160 million) are Homeless .
Homelessness is a mark of failure for communities in providing basic security. Based on national reports, about 2 percent of the world’s population may be homeless and another 20 percent lacks adequate housing. Reasons for homelessness include “shortages of affordable housing, privatization of civic services, investment speculation in housing, unplanned and rapid urbanization, as well as poverty, unemployment and family breakdown. Also contributing is a lack of services and facilities for those suffering from mental illness, alcoholism or substance abuse and displacement caused by conflicts, natural disasters and government housing policies.” Even people with jobs can struggle to keep homes. Homelessness was once considerably less visible. In 1950, for example, 70 percent of the world’s population of 2.5 billion was spread out across rural areas. Housing problems, far removed from urban centers, were largely unnoticed. Today, most of the world’s population of 7.6 billion, 55 percent, is concentrated in urban centers, in close proximity to the politically influential and economically well-to-do. Causes of homelessness across countries are multifaceted, though some factors stand out, including shortages of affordable housing, privatization of civic services, investment speculation in housing, unplanned and rapid urbanization, as well as poverty, unemployment and family breakdown. Also contributing is a lack of services and facilities for those suffering from mental illness, alcoholism or substance abuse and displacement caused by conflicts, natural disasters and government housing policies. In some cases, too, homelessness leads to alcoholism, substance abuse and mental illness. In many countries the prices to buy or rent homes are relatively high and rising faster than wages. Urban “gentrification” leading to rising property values and rental rates push low-income households into precarious living arrangements including slums, squatter settlements and homelessness.
