Homelessness and mental health

In a study in Western societies, homeless people have a higher prevalence of mental illness when compared to the general population. They also are more likely to suffer from alcoholism and drug dependency. A 2009 US study, estimated that 20–25% of homeless people, compared with 6% of the non-homeless, have severe mental illness. Others estimate that up to one-third of the homeless have a mental illness. In January 2015, the most extensive survey ever undertaken found 564,708 people were homeless on a given night in the United States. Depending on the age group in question and how homelessness is defined, the consensus estimate as of 2014 was that, at minimum, 25% of the American homeless—140,000 individuals—were seriously mentally ill at any given point in time. 45% percent of the homeless—250,000 individuals—had any mental illness. More would be labeled homeless if these were annual counts rather than point-in-time counts.
