The study has been conducted on behalf of the Region Västra Götaland in co-operation with the City of Göteborg, The Göteborg Region Association of Local Authorities (GR) and Business Region Göteborg. The study is about migration. Positive migration is the single most important sign that people believe that there are opportunities and a possibility of living a good life in a city or region. The more opportunities people see, and the more people who see these opportunities, the larger the net inflow will be. This is valid for people with radically different backgrounds: for rich and for poor; for people seeking the most advanced, well-paid jobs and for people seeking any kind of work; for people just looking for a better life and for people trying to escape oppression and violence. This is important. A city or region has to be attractive for all groups: for the native population as well as for people coming from abroad with different skills, cultures and resources. Only diverse, heterogeneous places are attractive. Sustainable migration can therefore only exist if there is attractiveness, openness and integration in a city or region.
