This dissertation examines the role in the migration process between Sweden and Finland of the Swedish-speaking minority group, the Finland Swedes. The causes underlying migration, as well as the integration of the group in Sweden, constitute the main focuses of the study.

It is concluded that Finland Swedes are over-represented in the total migration process from Finland to Sweden. As such, the process is culturally embedded in the group’s ethnic identity, which causes migration both through the practical minority situation in Finland, and through ethnic affinity with Sweden. Further causes include the substantial, circular networks of cultural, social and economic contacts between Sweden and Finland.

In the integration process, the transformation of the group’s ethnic identity is the central area of analysis. Initially, the ethnic affinity with Sweden is transformed into strengthened loyalties to Finland. As early as the first generation of migrants, however, the Finland Swedes enter into a process of assimilation in Sweden.

The migration process reveals the complex identity construction of the Finland Swedes. The ethnic identity is constituted of relations both towards the Finnish-speaking majority group, and towards Sweden as an extended Swedish-speaking area. The ethnic identity is mediated through national and personal identities, which are linked to both Sweden and Finland.

The findings have been produced within the methodological framework of critical realism, using a multiple-method research design. An individually based, statistical data set focused on the extension of the Finland-Swedish migration pattern, whereas an in-depth interview study was used to analyse the deeper causes of migration and integration.
