Some researchers stress that the essence of the problem of homelessness is a failure of social mechanisms for locating people in more or less defined social positions (especially for graduates from orphanages or former prisoners), and social support from the immediate environment (family, local community), eg . in the case of the old, sick, experiencing domestic violence, unemployment. Kazimierz Frieske draws attention to the fact that the marginalizing effects of exclusion is exacerbated whenever the declining pool of resources to be shared between members of the human community, to them it is less, the sharper becomes the conventional criteria of "normality" and thus - less prone to help people in difficult situations.
An important problem of homelessness is lack of knowledge about the actual number of homeless people, which is based on a variety of sources is determined from 30 to even 300 thousand. The only authoritative source of knowledge in this field is the number of persons to whom assistance has been formally granted by the social welfare centers. This number is changed periodically, oscillating around a value of 30 thousand. In 2002 the figure was 31.382 people.
