Suicide rates from a global sample of 73 countries over the period 1990–2010 are empirically explored. We find evidence of an ‘N-shaped’ suicidal Kuznets curve between per capita income and suicide rates in the male population of 25–34, 34–54 and 55–74 age groups and the female population of the 55–74 age group. These results remain firm to several robustness checks.
