Thus, the current definition of homelessness unfortunately allows people to simplistically assume that homeless people, including refugees, are merely "without a place to live" when that is not the case. As numerous studies show, forced migration and displacement brings with it another host of problems including socioeconomic instability, "increased stress, isolation, and new responsibilities" in a completely new environment.For people in Russia, especially the youth, alcohol and substance use is a major cause and reason for becoming and continuing to be homeless. The United Nations Centre for Human Settlements (UN-Habitat) wrote in its Global Report on Human Settlements in 1995: "Homelessness is a problem in developed as well as in developing countries. In London, for example, life expectancy among homeless people is more than 25 years lower than the national average." Poor urban housing conditions are a global problem, but conditions are worst in developing countries. Habitat says that today 600 million people live in life- and health-threatening homes in Africa, Asia, and Latin America. For example, more than three in four young people had insufficient means of shelter and sanitation in some African countries like Malawi. "The threat of mass homelessness is greatest in those regions because that is where population is growing fastest. By 2015, the 10 largest cities in the world will be in Asia, Latin America, and Africa.
They are often faced with reduced access to private and public services and vital necessities:

Difficulty forming trust in relation to services, systems, and other people; exacerbating pre-existing difficulty accessing aid and escaping homelessness, particularly present in the chronically homeless. Statistics from the past twenty years, in Scotland, demonstrate that the biggest cause of homelessness is varying forms of relationship breakdown.There is sometimes corruption and theft by the employees of a shelter, as evidenced by a 2011 investigative report by FOX 25 TV in Boston, wherein a number of Boston public shelter employees were found stealing large amounts of food over a period of time from the shelters kitchen for their private use and catering. Homeless people are often obliged to adopt various strategies of self-presentation in order to maintain a sense of dignity, which constrains their interaction with passers-by, and leads to suspicion and stigmatization by the mainstream public.Homelessness is also a risk factor for depression caused by prejudice. When someone is prejudiced against people who are homeless, and then becomes homeless themselves, their anti-homelessness prejudice turns inward, causing depression. "Mental disorders, physical disability, homelessness, and having a sexually transmitted infection are all stigmatized statuses someone can gain despite having negative stereotypes about those groups."
