Bullying is a type of violence experienced by youth and it can happen in person and through technology.
Preventing bullying involves teaching kids safe ways to stand up against it and enhancing their interpersonal skills, like empathy and conflict management.
What is bullying?
CDC defines bullying as any unwanted aggressive behavior(s) by another youth or group of youths, who are not siblings or current dating partners. It involves an observed or perceived power imbalance, and is repeated multiple times or is highly likely to be repeated.
Bullying may inflict harm or distress on the victim including physical, psychological, social, or educational harm.1 Common types of bullying include:
Physical such as hitting, kicking, and tripping.Bullying can also occur through technology, called electronic bullying or cyberbullying.1 A young person can be a perpetrator, a victim, or both (also known as a "bully/victim").
Quick facts and stats
Bullying is an adverse childhood experience that is widespread in the United States. Bullying harms all youth involved including those who are bullied, those who bully others, and bystanders who witness it.
Bullying is common. About one in five high school students reported being bullied on school property in the past year. More than one in six high school students reported being bullied electronically in the past year including through texting and social media.2
Some youth experience bullying more than others. Female students were more likely than male students to experience bullying, both on school property and electronically. LGBTQ+ students were more likely than cisgender and heterosexual students to experience bullying, both on school property and electronically.
Additionally, Asian students and Native Hawaiian or other Pacific Islander students were less likely than Hispanic, White, and Multiracial students to be bullied at school. Native Hawaiian or other Pacific Islander students were less likely than students from most other racial and ethnic groups to be electronically bullied.2
Bullying is a frequent discipline problem. A national survey found that 28% of middle schools, 15% of high schools, and 10% of elementary schools reported the occurrence of bullying at school at least once a week. About 37% of middle schools reported the occurrence of cyberbullying at least once a week, followed by 25% of high schools and 6% of elementary schools.3
Warning signs
Not all children who are bullied show warning signs, but StopBullying.gov suggests being aware of these common signs:
Unexplained injuries.Outcomes
Bullying can result in physical injury, social and emotional distress, self-harm, and even death. It also increases the risk for depression, anxiety, sleep difficulties, lower academic achievement, and dropping out of school.
Youth who bully others are at increased risk for substance misuse, academic problems, and experiencing violence later in adolescence and adulthood.4 Youth who bully others and are bullied themselves suffer the most serious consequences and are at greater risk for mental health and behavioral problems.
Prevention
We all have a role to play in preventing bullying. Youth and adults play important roles in preventing violence and creating safe communities where young people can thrive.
A bystander (someone who witnesses bullying, either in person or online) can make a positive impact by becoming an upstander. An upstander is someone who sees what happens and intervenes, interrupts, or speaks up to stop the bullying. Learn more about becoming an upstander and take action against bullying.
Keep the lines of communication open by checking in with kids often and listening to them.

Additionally, school-based programs that strengthen youths' interpersonal and emotional skills, including empathy, conflict management, and teamwork, can reduce bullying. Explore example program resources.
All young people deserve to grow up safely and thrive. We can all be upstanders and help stop bullying in our communities.
