Information on vital status was obtained from the Population Register Center, which tracks all vital events in Finland. Dates of death and emigration were obtained to 2011. Causes of death were obtained from Statistics Finland. Suicide cases were identified from International Classification of Diseases rubrics. Forensic autopsy by specialist forensic pathologists with support from forensic chemical analyses is mandatory in Finland for sudden and unexpected deaths. Thus the diagnosis of suicide on official death certificates in Finland is considered reliable and valid (Varnik et al. 2012).
