This chapter describes current changes in migration flows and politics in Sweden, before presenting and discussing the reactions to these changes in civil society – the mobilization of both pro- and anti-migration sentiments – which reflect the polarized sentiments towards immigration in Swedish society.First, this report conveys information about migration flows to Sweden before, during and after the refugee reception crisis of 2015. In 2016 in particular, Sweden had a major intake of asylum seekers, which prompted new legislative measures to manage this. Second, we emphasize transformations in the party-political landscape before, during and after the refugee reception crisis of 2015. In this period there was also a rhetorical shift in mainstream politics, heralding an emphasis on security in order to protect the Swedish model. The mainstream-right bloc was also split in two. Third, we study the actions and reactions in response to these changes in civil society. The everyday experiences of problems with integration stand in contrast with international norms of solidarity. We conclude that the crisis enabled a window of opportunity for the mobilization of both pro- and anti-migration sentiments in civil society.
