Abstract: Suicide deaths are defined as deaths due to “intentional self-harm” in accordance with the International Statistical Classification of Diseases and Related Health Problems 10th Revision. However, “ill-defined and unknown causes of mortality,” “accidents,” and “event of undetermined intent” may also account for hidden suicides. This study compared the state of deaths due to suicide and ill-defined/undetermined causes across urban areas in Japan over the past 15 years using vital statistics.
