The Korea Institute for Health and Social Affairs published "Some Causes of Psycho-social Anxiety in Korea and How to Address Them" last month.
The report is based on an online survey of 5,000 adolescents aged 14-18 conducted from August to September last year.
In the survey, 79.4 percent of adolescents said Korean society was either very unequal or unequal. Sixty percent said Korean society was unstable or very unstable. A total of 44.2 percent said they did not trust people.
The level of anxiety about the country's future was 6.6 out of 10.
This figure tended to rise with age, with high school students exhibiting more anxiety than middle school students. This is attributed to the concerns over the highly competitive process of getting into university.
University students' level of anxiety was 6.8, presumably because of the tough job market awaiting them on graduation.
The youngsters said they were anxious about frequent changes in education and university entrance policies, followed by politics, foreign affairs and safety.
