Abstract

In this online appendix we provide additional information and analyses to support "The Determinants of Social Connectedness in Europe." We include a number of case studies illustrating how language, history, and other factors have shaped European social networks. We also look at the effects of social connectedness. Our results provide empirical support for theoretical models that suggest social networks play an important role in individuals' travel decisions. We study variation in the degree of connectedness of regions to other European countries, finding a negative correlation between Euroscepticism and greater levels of international connection.
