The mean girls — and boys — may be losing members.

April 13 is International Day of Pink, a day against bullying and discrimination, but there’s some good news to report: The rate of school bullying among children ages 12 to 18 fell to 22% in 2013 after stubbornly remaining at 28% in 2005, 2009 and 2011 and briefly rising to 32% in 2009, according to a report released by the U.S. Department of Education’s National Center for Education Statistics in 2015. Cyber bullying among that age group also fell from 9% in 2011 to 7% in 2013, the latest date for which data is available. The report cites data from the government’s 2013 School Crime Supplement of the National Crime Victimization Survey, the nation’s primary source on crime and victimization, which comprises 90,000 households and 160,000 people of all ages.

Other studies, however, suggest that school bullying could be moving online. One in five adults said technology makes bullying easier, according to a Harris Poll of over 2,000 adults released in February 2016. The lifetime cyberbullying victimization rates average 26% of the overall population over the last decade, but has risen to 34% in February 2015 from 24% in October 2013 and 19% in May 2007, according to the Cyberbullying Research Center. On average, about 16% of the students who have been a part of the center’s nine studies involving 15,000 students since May 2007 have admitted that they have cyberbullied others at some point in their lifetime, although teen cyberbullying has fallen to 14.6% in February 2015 from 17% in January 2014. Any decline is good news, Esquith says, “but at the same time there’s still a lot of work to be done.”

The International Day of Pink, started in 2007, encourages schools to take an anti-bullying pledge and put up posters to combat school bullying. Other annual anti-bullying events include National Bullying Prevention Month in October, originally started as an awareness week in 2006 by the Parent Advocacy Coalition for Educational Rights or PACER, a Bloomington, Minn.-based nonprofit. It encourages people to sign a digital petition, “The End of Bullying Begins With Me.” Bullying is still a public health problem: A study published in the June 2015 edition of the British Medical Journal found that 13-year-olds who were bullied are three times as likely to be bullied as adults, and childhood bullying is ultimately responsible for 30% of depression in adults.

What’s more, a higher percentage of females than males ages 12 to 18 reported being bullied at school in 2013 (24% versus 19%), the U.S. Department of Education’s National Center for Education Statistics also found. A higher percentage of white (24%) and black students (20%) than Hispanic (19%) and Asian students (9%) reported being bullied. Higher percentages of students in grades 6 through 11 than of students in grade 12 also reported being bullied at school during the school year. Approximately 14% of 12th-graders reported being bullied at school, compared with 28% of sixth-graders. “Bullying remains a serious issue for students and their families,” the report concluded.

“ Some studies suggest that school bullying could be moving online, rising to 34% last year from 19% in 2007 ”

It appears that there are few safe spaces for the victims of bullying in schools. Bullying most often occurs in the hallway or stairwell of schools and in classrooms, most likely between lessons, says David Esquith, director at the Office of Safe and Healthy Students at the Department of Education. Bullying was identified if another student had made fun of them, called them names, or insulted them; spread rumors about them, threatened them with harm; pushed, shoved, tripped, or spat on them; tried to make them do something they did not want to do; excluded them from activities; and/or destroyed their property. An adult was notified in less than 50% of cases.

Students’ chances of being bullied rise 25% if they move from a group with average popularity to the 95th percentile, beyond which victimization begins to drop, according to a paper, “Causality of Social Combat: School Networks of Peer Victimization and Their Consequences,” published in the April 2014 American Sociological Review, which surveyed 4,200 high-school students. (Popularity was based on friendship nominations among students.) Those with higher social status also experienced stronger adverse psychological consequences when bullied as they felt like they had more to lose.

Why the decrease in bullying, at least in schools? “Anti-bullying campaigns at the federal, state and local level may be paying off,” Esquith says. “Parents and schools and students are also working together to prevent it and help those kids who are being bullied.” StopBullying.gov, for instance, coordinates with the Federal Partners in Bullying Prevention Steering Committee, an interagency effort led by the Department of Education. The “It Gets Better Project,” started by writer Dan Savage and his husband Terry Miller brought attention to the issue of teenagers who committed suicide because they were gay or their peers thought they were gay.
