Homelessness, as a form of life, is one of the most serious social and welfare problems nowadays. The problem of homelessness shows the defects of welfare (unemployment care, child and youth care), different social (law enforcement) systems of provision and certain legal regulations (e.g. no proper regulations protecting the rights of tenants). On the other hand homelessness can be the cause of other serious - not yet solved - problems like criminality, alcoholism and the lack of solidarity of the society. According to examinations alcoholism goes together with homelessness, it is a kind of escape from a hopeless situation and in many cases it is the first step of becoming homeless. In these social groups in most of the cases crime is the result of anger caused by alcohol or crime simply makes it easier to become a victim. There are others who become homeless after serving their prison sentence. These problems must not be separated; they should be examined and treated as a whole because they are in a very close connection. We have to try to find the right solutions and apply the right means in order to solve the problem of homelessness.
