Suicide rates are deaths deliberately initiated and performed by a person in the full knowledge or expectation of its fatal outcome. The rates have been directly age-standardised to the 2010 OECD population to remove variations arising from differences in age structures across countries and over time. Comparability of data between countries is affected by a number of reporting criteria, including how a person's intention of killing themselves is ascertained, who is responsible for completing the death certificate, whether a forensic investigation is carried out, and the provisions for confidentiality of the cause of death. Caution is required therefore in interpreting variations across countries. This indicator is measured as deaths per 100 000 inhabitants (total, men, women).

Suicide is death caused by injuring oneself with the intent to die. A suicide attempt is when someone harms themselves with any intent to end their life, but they do not die as a result of their actions. Many factors can increase the risk for suicide or protect against it. Suicide is connected to other forms of injury and violence. For example, people who have experienced violence, including child abuse, bullying, or sexual violence have a higher suicide risk. Being connected to family and community support and having easy access to healthcare can decrease suicidal thoughts and behaviors
