The purpose of this study is to describe and analyze homelessness in a medium-sized municipality from an organizational perspective. Some of the central questions in this study are: How is the cause of homelessness explained? How do different actors in the community address, prevent and combat homelessness? Who is responsible for the homelessness? This study is based on four semi-structured interviews with organizations that work with homelessness. The analysis is based on problem definition theory. The result of this study shows that homelessness is a problem in this medium-sized municipality even if it is not a big one and that it is often closely combined with substance abuse. The responsibility for the homeless is on the homeless themselves and the social service because that causes is, according to this study, individual based.
