Does Religion Stave Off the Grave? Religious Affiliation in One’s Obituary and Longevity

Abstract

Self-reported religious service attendance has been linked with longevity. However, previous work has largely relied on self-report data and volunteer samples. Here, mention of a religious affiliation in obituaries was analyzed as an alternative measure of religiosity. In two samples (N = 505 from Des Moines, IA, and N = 1,096 from 42 U.S. cities), the religiously affiliated lived 9.45 and 5.64 years longer, respectively, than the nonreligiously affiliated. Additionally, social integration and volunteerism partially mediated the religion–longevity relation. In Study 2, exploratory analyses suggested that the religion–longevity association was moderated by city-level religiosity and city-level personality. In cities with low levels of trait openness, the nonreligiously affiliated had reduced longevity in highly religious cities relative to less religious cities, consistent with the religion-as-social-value hypothesis. Conversely, in cities with high levels of openness, the opposite trend was observed, suggesting a spillover effect of religion. The religiously affiliated were less influenced by these cultural factors.
