What is the thread that unites tourism and migration? A review of existing literature suggests two forms of tourism linked to migration: visiting friends and relatives and second home tourism. Tourism related to visiting friends and relatives can be stimulated by migratory movements, and, in turn, gives rise to new migrations. Second home ownership, however, serves as the main connection between tourism and migration, promoting tourism that generates from or relates to current and past migrations. This exploratory study is based on a qualitative systematic literature review and focuses on the characteristics of second home and visiting friends and relatives-related tourism, and migration, in order to clarify little studied linkages among them that can affect tourism-related development. The study shows that many of the migration-led tourism segments reflect factors that may promote sustainable development.
