Ethnic residential segregation is a phenomenon that is increasing in prevalence in Swedish societies. Integration is a major challenge in both large and small municipalities. The purpose of this study was to analyze how some Swedish municipalities work to counteract ethnic residential segregation and promote integration, both spatially and in society. A qualitative document study has been made of the four selected municipalities' planning documents, in order to gain an understanding of how ethnic residential segregation can be counteracted by means of urban planning and integration strategies. The municipalities selected are Örebro, Umeå, Borlänge and Luleå, which have varying degrees of ethnic residential segregation. The analysis shows that the subject is very complicated and that there are many factors to consider. In addition to well-thought-out urban planning, short-term solutions for integration into society are also required, which municipalities should take a position on, in the form of developed integration efforts. This can be decisive for how quickly and well immigrants are integrated into Swedish society. Finally, it is concluded that more research is needed on how municipalities should work to promote integration in communities already suffering from ethnic residential segregation.
