Despite the danger of excessive internet use and the threat of bullying, most teenagers around the world are "relatively" happy with their lot, a major OECD survey showed Wednesday.
Asked to rate their satisfaction with life on a scale of 0 to 10, some 370,000 15-year-olds gave a mean score of 7.3, the Paris-based group said.
The respondents were among 540,000 from 72 countries that took part in a larger survey conducted by the OECD's Programme for International Students Assessment (PISA) in 2015.
The survey found great disparities between countries, with fewer than four percent of students in the Netherlands saying they were "not satisfied" with life, a figure that rises to more than 20 percent in South Korea and Turkey.
Boys were happier overall, with 39 percent reporting being "very satisfied" compared with 29 percent of girls, the Organisation for Economic Cooperation and Development report said.
In 34 of the countries studied, more than 10 percent of the students said their classmates make fun of them several times a month.
Around four percent reported being hit or pushed several times a month, while 7.7 percent said they were victims of physical harassment several times a year.
