Promotion of mental health and well-being is recently recognized as a health priority at the global level. In Mongolia, mental health issues have been on the rise. However, less is known on socioeconomic inequality in mental health in the country. The aim of this study is to examine socioeconomic inequality in mental health in the adult population in Mongolia. This study analyzed the data of 30,567 adults from the Household Socio-Economic Survey, collected in 2012 by the National Statistical Office of Mongolia. Self-reported mental health was used as a health outcome variable. Socioeconomic status was measured by household income. We employed the Wagstaff's concentration index to assess the degree of socioeconomic inequality in mental health. The results show that the prevalence of self-reported mental health was 1.17% among the respondents. The adults living in urban areas suffer significantly more with mental illness compared to the adults living in rural settlements. The Wagstaff's concentration index for mental health was significantly negative (-0.243), indicating that mental health problems were concentrated among the lower-income groups. The decomposition results show that education, economic activity status and marital status were the main contributors to socioeconomic inequalities in mental health after removing age-sex related contributions. Socioeconomic inequality in mental health exists in the adult population in Mongolia, which was mainly explained by the education level, employment and marital status. Prospective policies are needed to reduce socioeconomic inequality in mental health in the country. Socioeconomic inequality in mental health exists in Mongolia. It calls for further policy actions.
