Do diverse geographical contexts lead to diverse friendship networks? A multilevel analysis of Belgian survey data

The choice-constraint approach assumes that the choice of one’s friends will be determined by both individual choices and the constraints imposed by one’s interaction context. Trends towards homophily however, might counteract this effect if actors consistently seek interaction partners with the same background characteristics. In this study we investigate the impact of community level diversity on the cultural diversity of friendship networks. Based on a multilevel analysis of recent survey data from Flanders (Belgium), we demonstrate that community level diversity has a significant but limited impact on ethnic and religious friendship network diversity. Controlling for individual level characteristics, residents of ethnically diverse communities report more ethnically and religiously diverse friendships. The fact that ethnic and religious diversity overlap to such a large extent suggests that both divisions are closely related in contemporary secularized European societies. © 2011 Elsevier Ltd.
