At the Cyberbullying Research Center we have been collecting data from middle and high school students since 2002. We have surveyed more than 30,000 students from middle and high schools from across the United States in fourteen unique projects. The following two charts show the percent of respondents who have experienced cyberbullying at some point in their lifetime across our twelve most recent studies. Our two earliest studies (from 2004 and 2005) are excluded from this because they were online convenience samples and therefore cannot be easily compared to the other studies. The twelve most recent cyberbullying studies have all been random samples of known populations which allows for improved reliability, validity, and generalizability. Please see our Research in Review addendum for more details about each of the samples.
As illustrated in the chart above, the rates of cyberbullying victimization have varied over the years we have studied the phenomenon. On average, about 29% of the students who have been a part of our most recent 12 studies have said they have been the victim of cyberbullying at some point in their lifetime. The rates of cyberbullying offending have also varied among the research studies we have conducted. On average, about 16% of the students who have been a part of our last 12 studies have admitted that they have cyberbullied others at some point in their lifetime.

When it comes to more recent experiences, an average of about 12% of students have been cyberbullied across all of our studies within the 30 days prior to the survey. There does appear to be a trend over the last 5 years or so of this rate increasing steadily. For offending, across all of our studies, 6% of students admit to cyberbullying others.
