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. It is 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 suffer from 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<unk>  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. Being chronically homeless also means that people with mental illnesses are more likely to experience catastrophic health crises requiring medical intervention or resulting in institutionalization within the criminal justice system. Majority of the homeless population do not have a mental illness. Although there is no correlation between<unk> , those who are dealing with<unk>  are struggling with psychological and emotional distress. The Substance Abuse and Mental Health Services Administration conducted a study and found that in 2010, 26.2 percent of sheltered homeless people had a severe mental illness. Nikes and Homeless Studies have found that there is a correlation between<unk>  and incarceration. Those with mental illness or substance abuse problems were found to be incarcerated at a higher frequency than the general population. Fischer and Breakey have identified the chronically mentally ill as one of the four main subtypes of homeless persons; the others being the street people, chronic alcoholics, and the situationally distressed. The first documented case of a psychiatrist addressing the issue of<unk>  was in 1906 by Karl Wilmanns.
