Half of all high school students say they have bullied someone in the past year, with nearly as many saying they have been the victims of bullying, according to a new study released this week.

The study of the “Ethics of American Youth” released Tuesday surveyed more than 40,000 high school students and has been conducted every other year since 1992.

The study by the non-profit Josephson Institute of Ethics also found that one-third of all high school students say that violence is a big problem at their school, and nearly one in four say they do not feel very safe there. The problem is much less pronounced at private schools, where the figures drop to less than 10 percent in those two categories.

Weapons are also a part of the mix with 10 percent of all students saying they took a weapon to school at least once in the past 12 months, and 16 percent admitting that they have been intoxicated at school. More than half admit to hitting someone within the last year because they were upset.
