Purpose: The etiology of suicide can be biological, genetic, psychological, or sociological. However few studies have been done about socioeconomic etiology. This study investigates the relationship between the suicidal rate of countries in the world and their socioeconomical factors such as national products, income, and population density.
Materials and Methods: The men and women’s suicidal rates and socioeconomic variables of the countries in the world were adopted from the Human Development Report 2013 by United Nations Development Programme and The World Factbook 2012 by the Central Intelligence Agency of the United States. The relationship between these variables were analysed by Pearson’s correlation coefficient.
Results: Male suicidal rate was higher than female’s and the national rates of suicide showed statistically different values according to their geographical location. Male and female suicidal rate had a positive correlation with each other and both male and female suicidal rates had positive correlation with Human Development Index 2013. Gross domestic product per capita and gross national income per capita showed positive correlation with female suicidal rate, and trust in national government had a negative correlation with only male suicidal rate.
Conclusion: Socioeconomic variables such as Human Development Index, gross national income or
domestic products per capita, and trust in government, had correlation with the suicidal rate of countries in the world. These results suggest that socioeconomic factors may also explain a part of the suicidal rate of the country as well as already well-known genetic, biological, and psychiatric factors.
