With the rise of the Internet comes new ways for students to torment each other, and student suicides have called new attention to bullying in schools.

As part of National Bullying Prevention Month and World Bullying Prevention Day on Oct. 7, we have compiled some staggering facts about how big a problem bullying is in America's schools. Our sources include the National Education Association, PACER Center, and Make Beats Not Beatdowns.

Bullies often go on to perpetrate violence later in life: 40% of boys identified as bullies in grades 6 through 9 had three or more arrests by age 30.

One of every 10 students who drop out of school do so because of repeated bullying.

75% of school shooting incidents have been linked to bullying and harassment.

64% of children who were bullied did not report it.

Nearly 70% of students think schools respond poorly to bullying.

Bullying has serious side effects — students who are targets experience extreme stress that can lead to symptoms of physical illness and a diminished ability to learn, according to the National Education Association.

Schools have come under fire recently for not doing enough to prevent student suicides related to bullying in schools, and because bullying is becoming even harder to track, some school districts are now paying services to track students on social media.
