This chapter examines the global epidemiology of suicidal behaviour. Up to one million people die by suicide every year, and about three quarters of these are in low- and middle-income countries. Twenty to thirty times this number harm themselves or attempt suicide. Global rates are probably under-reported, and the iceberg model of suicidal behaviour (showing that much suicidal behaviour is ‘under the waterline’ and thus hidden) is a helpful way of conceptualizing this. In most countries, men are greatly over-represented amongst people who die by suicide. There is a current concern about men in midlife in many high-income settings. Although suicidal behaviour can vary widely in incidence, it tends to share common antecedents. However, it should be borne in mind that the results of large population-based studies do not always apply to individuals.
