CHICAGO (CBS) — A survey of Illinois high school students indicates that younger white teenage girls are the most likely of any demographic to be bullied.

As WBBM Newsradio’s Mike Krauser reports, 21 percent of Illinois high school students report being bullied at school, according to the survey by researchers at Lurie Children’s Hospital. Eleven percent reported being involved in a physical fight.

“And that tends to be heavier for younger kids, and that’s pretty typical – all the risk behaviors, kind of the 9th and 10th graders, and then by 11th and 12th, they kind of settle down a little bit,” said Dr. Jennifer Cartland, who directs research for the hospital.

Cartland says surprisingly, girls are twice as likely as boys to be bullied electronically.

“Well, I’m not a psychologist, but I do think in general, it’s understood that girls tend to deal with bullying issues – they’re more likely to use verbal means, and they’re more likely to use social isolation and other techniques, and maybe those things are easier to do through the Internet.

The study concluded that younger white teenage girls are the most likely of all to be bulled. It also showed that white students most frequently report being bullied at school and electronically, and boys are twice as likely as girls to report being in a physical fight at school.
