Previous valuable research has examined the effect individual-level social and psychological factors have on suicidality. However, scholarship has yet to investigate the role civil society participation plays in suicide rates cross-nationally. Thus, this study examines the effect civil society participation has on suicide rates in 156 countries from varying levels of development from 2000 – 2019 from Africa, Asia, Europe, Latin America, the Middle East, and North America. When including standard controls and controlling for potential endogeneity, the findings indicate that civil society participation, both political and non-political, has a negative and statistically significant effect on suicide rates. The results suggest that both political and non-political forms of civil society participation may produce positive social and psychological benefits that are associated with lower suicide rates.
