The most common causes of suicide were relationship issues, and the method mostly utilized was drugs or chemicals. The rate of suicide attempts for the age under 24 has increased with calendar years, and this is consistent with the national data. During the period affected by the COVID-19 pandemic (2020 and 2021), both the rate of suicide attempts and suicidal ideation under the age of 24 rose noticeably.
