Background: It is recognized that socioeconomic status (SES) has a significant impact on health and wellbeing; however, the effect of SES on suicide is contested. This study explored the effect of SES in suicide deaths and de-composed inequality into its determinants to calculate relative contributions.Methods: Through a cross-sectional study, 546 suicide deaths and 6,818 suicide attempts from January 1, 2010 to December 31, 2014 in Ilam Province, Western Iran were explored. Inequality was measured by the absolute con-centration index (ACI) and decomposed contributions were identified. All analyses were performed using STATA ver. 11.2 (Stata Corp., College Station, TX, USA).Results: The overall ACI for suicide deaths was -0.352 (95% confidence interval, -0.389 to -0.301). According to the results, 9.8% of socioeconomic inequality in suicide deaths was due to addiction in attempters. ACI ranged from -0.34 to -0.03 in 2010–2014, showing that inequality in suicide deaths declined over time.Conclusion: Findings showed suicide deaths were distributed among the study population unequally, and our re-sults confirmed a gap between advantaged and disadvantaged attempters in terms of death. Socioeconomic in-equalities in suicide deaths tended to diminish over time, as suicide attempts progressed in Ilam Province.
