Half of the world's kids fear the online bully, report says

In the laundry list of universal kid fears -- monsters, nightmares, kidnappers, mean big kids -- we may soon be able to add cyberbully.

According to data collected by Microsoft's Safety & Security Center, 54% of kids worldwide say they worry about being bullied online, and nearly 1 in 4 say they have experienced online bullying. Additionally, 24% admitted to having bullied someone else online. Online bullying is still less frequent than off-line bullying in almost all the countries included in the report. Worldwide, 72% of kids surveyed said they have been bullied off-line, compared with 37% who say they have been bullied online. The two exceptions to this rule were China and Singapore. The researchers found that 80% of kids in China say they worry about being bullied online and 70% of kids say they have been bullied online. Both numbers are way above the worldwide average.
