Specific populations at risk for suicide differ considerably according to region, country, sex, age, and the most common suicide methods used, highlighting the need for ongoing systematic surveillance to inform prevention efforts. The magnitude of the problem is not limited to suicide deaths. It is estimated that for every suicide, there are 20 more persons who have made an attempt. Individuals who have made a suicide attempt are at increased risk for dying by suicide. This chapter explores differences in the suicide and suicide attempt rates in the general population on different continents, by examining data from the World Health Organization (WHO) Global Health Estimates and the World Mental Health Survey Initiative. Differences across contexts in suicidal behaviours and the need for ongoing monitoring are emphasized.
