This section pulls together fundamental information about bullying, including:
Definition of Bullying
In 2014, the Centers for Disease Control and Department of Education released the first federal definition of bullying. The definition includes three core elements:
- unwanted aggressive behavior
- observed or perceived power imbalance
- repetition or high likelihood of repetition of bullying behaviors
This definition helps determine whether an incident is bullying or another type of aggressive behavior or both.
Research on Bullying
Bullying prevention is a growing research field that investigates the complexities and consequences of bullying. Important areas for more research include:
- Prevalence of bullying in schools
- Prevalence of cyberbullying in online spaces
- How bullying affects people
- Risk factors for people who are bullied, people who bully others, or both
- How to prevent bullying
- How media and media coverage affects bullying
What We’ve Learned about Bullying
- Bullying affects all youth, including those who are bullied, those who bully others, and those who witness bullying. The effects of bullying may continue into adulthood.
- There is not a single profile of a young person involved in bullying. Youth who bully can be either well connected socially or marginalized, and may be bullied by others as well. Similarly, those who are bullied sometimes bully others.
- Solutions to bullying are not simple. Bullying prevention approaches that show the most promise confront the problem from many angles. They involve the entire school community—students, families, administrators, teachers, and staff such as bus drivers, nurses, cafeteria and front office staff—in creating a culture of respect. Zero tolerance and expulsion are not effective approaches.
- Bystanders, or those who see bullying, can make a huge difference when they intervene on behalf of someone being bullied.
- Studies also have shown that adults can help prevent bullying by talking to children about bullying, encouraging them to do what they love, modeling kindness and respect, and seeking help.
Here are federal statistics about bullying in the United States. Data sources include the Indicators of School Crime and Safety: 2019 (National Center for Education Statistics and Bureau of Justice) and the 2017 Youth Risk Behavior Surveillance System (Centers for Disease Control and Prevention).

State and Local Statistics
Follow these links for state and local figures on the following topics:
According to the UNESCO Institute of Statistics:
- One third of the globe’s youth is bullied; this ranges from as low as 7% in Tajikistan to 74% in Samoa.
- Low socioeconomic status is a main factor in youth bullying within wealthy countries.
- Immigrant-born youth in wealthy countries are more likely to be bullied than locally-born youth.
Bullying and Suicide
The relationship between bullying and suicide is complex. The media should avoid oversimplifying these issues and insinuating or directly stating that bullying can cause suicide. The facts tell a different story. It is not accurate and potentially dangerous to present bullying as the “cause” or “reason” for a suicide, or to suggest that suicide is a natural response to bullying.
- Research indicates that persistent bullying can lead to or worsen feelings of isolation, rejection, exclusion, and despair, as well as depression and anxiety, which can contribute to suicidal behavior.
- The vast majority of young people who are bullied do not become suicidal.
- Most young people who die by suicide have multiple risk factors.
