The aim of the thesis is to investigate swedish lifestyle migrants living in Barcelona, the reason for the migration and how they affect and experience the ongoing gentrification of the city. The research method was qualitative with interviews. Four swedish lifestyle migrants that have been living in Barcelona for 2 to 14 years were interviewed. The interviews focused on the interviewees migration and lifestyle, housing situation and their experience and perception of Barcelona and its inhabitants.The result showed that the swedish lifestyle migrants moved to Barcelona because they were longing for a new lifestyle, rather than there was a reason they moved to Barcelona specifically. The swedish lifestyle migrants experience the gentrification of Barcelona through social resistance from the locals. With this, the open climate within the international community results in a self-segregation. In the beginning, the swedish lifestyle migrants usually live in the most touristic, central parts of Barcelona. After establishing an everyday life, the swedish lifestyle migrants tend to move to less touristy, but still central areas. By doing so the swedish lifestyle migrants affects the gentrification of the city by contributing to the displacement of the locals and changing the social atmosphere of the area.
