About 78 million people in India live in slums and tenements. 17% of the world's slum dwellers reside in India. Subsequent to the release of "Slumdog Millionaire" in 2008, Mumbai was a slum tourist destination for slumming where homeless people and slum dwellers alike could be openly viewed by tourists. Homelessness is in part a direct result of families migrating from rural to urban cities and urbanization. Migration to urban areas can occur for a variety of reasons ranging from loss of land, need for sustainable employment, lack of clean water and other resources, and in some cases like the Bargi Dam Project, loss of all property and complete displacement. Once reaching cities, homeless attempt to create shelters out of tin, cardboard, wood, and plastic. Slums can provide an escape, yet individuals often cannot afford them. Homeless individuals may experience abuse, maltreatment and lack of access to schools and healthcare. Some other problems leading to homelessness include: disability (either mental, physical, or both), lack of affordable housing (a basic apartment in India costs approximately US$70 per month), unemployment (either seasonal or through economic hardships), and changes in industry. Desertion of the old, mentally ill, unmarried pregnant women, helpless divorced women and girl children also are some of the main causes of homelessness in India. Jobs involving heavy industry and manufacturing (that require only a high school level of education) are being replaced by service industry jobs (which may or may not require a higher level of education). Since university is less affordable for the average Indian than it is for the average North American or European citizen due to their lower per capita income level, more people in India are becoming unemployable for the jobs of the 21st century. The average per capita income for a citizen of India is barely more than US$1,200; compared to US$54,510 in Canada and more than US$64,800 in Switzerland. Policymakers attribute the following factors as the main causes of homelessness: drug abuse, mental illness, relationship failures, and domestic abuse. These place responsibility and blame directly on the homeless. Policies related to ‘deinstitutionalization of care for mentally ill people and subsequent abandonment of a family member with mental illness by the family’ have also increased the number of people living without a roof over their heads. Street children fall under the broader category of children in especially difficult circumstances (CEDC), and are considered the most threatened of all children in CEDC.
