Although research has been conducted on individual social and psychological factors on suicide rates, there has yet to be any exploration into the role of civil society participation. This article investigates whether civil society participation influences suicide rates cross-nationally. The study hypothesizes that both political and non-political participation can reduce suicide rates by providing social and psychological benefits. Using data from 2000 to 2019 across 156 countries, as well as controlling standard variables and endogeneity, they find that both political and non-political civil society participation have a negative and statistically significant effect on suicide rates. The conclusion is that engagement in civil society, whether political or non-political, may help lower suicide rates nationally.
