At the Cyberbullying Research Center we have been collecting data from middle and high school students since 2002. We have surveyed more than 20,000 students from middle and high schools from across the United States in twelve unique projects. The following two charts show the percent of respondents who have experienced cyberbullying at some point in their lifetime across our ten 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 ten most recent studies have all been random samples of known populations which allows for improved reliability and validity. 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 28% of the students who have been a part of our most recent 10 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 10 studies have admitted that they have cyberbullied others at some point in their lifetime.
