Religion and Volunteering in Context: Disentangling the Contextual Effects of Religion on Voluntary Behavior

This study examines whether religion's effect on volunteering spills over to nonreligious individuals through personal ties between religious and nonreligious individuals. We use three different analytic strategies that focus on national, local, and personal network level contexts to identify the network spillover effect of religion on volunteering. We find that if nonreligious people have close friends with religious affiliations, they are more likely to volunteer for religious and nonreligious causes. However, this network spillover effect cannot be inferred from the relationship between volunteering and national or local level religious context-a common approach in the literature. In fact, we find that the average level of local religious participation is negatively associated with volunteering among the nonreligious in the United States. This novel finding suggests that to fully understand religion's civic role in the wider community, we need to consider how religion might influence the civic life of people outside religious communities, not just those within them. Our findings also suggest that in spite of methodological advances, studies that purport to test mechanisms at one level of analysis by using data at a larger level of aggregation run a high risk of committing an ecological fallacy.
