bullying stats

I seem to be on various edu-p.r. lists these days, which is interesting. Today's "Media Advisory," from "The National School Boards Association's Council of Urban Boards of Education," contains this result from a survey of "10,270 parents in 112 urban schools from 17 states":

Bullying continues to be an issue at school. Little more than half of the parents surveyed felt that teachers had the ability to stop bullying, with close to 30 percent not sure if this was possible. More than 25 percent of parents have spoken to an administrator about bullying. Parents with students in the middle grades (6-8) were the largest group (nearly 11 percent) to report that their child was bullied during the school day at least once per month.

I'd love to know what figures you'd see in a survey of suburban, parochial, & private school parents.
