This study examines political media consumption among non-resident citizens, and whether following politics in traditional and social media in their country of residence and origin has a mobilizing effect on voting in origin-country elections. The topic of our study is inspired by the trend towards increased enfranchisement of external citizens, improved methods for participation from abroad, and the transformation of the media landscape with enhanced possibilities for external voters to follow politics in their country of origin. Based on a survey directed towards a stratified random sample of Finnish external citizens in 15 countries, we find that politically oriented media consumption in the country of origin substantially increases the likelihood of participating in origin-country elections and that this effect holds for traditional media channels as well as for social media. A corresponding mobilizing effect is, however, not found for following politics in the country of residence. This demonstrates the value of relevant information for political participation.
