“Video game popularity and real-world youth violence have been moving in opposite directions. Violent juvenile crime in the United States reached a peak in 1993 and has been declining ever since. School violence has also gone down. Between1994 and 2001, arrests for murder, forcible rape, robbery and aggravated assaults fell 44 percent, resulting in the lowest juvenile arrest rate for violent crimes since 1983.”
Our survey of more than 1200 middle school students found that 29 percent of girls who played video games listed at least one M-rated game among the games they’d ‘played a lot’ during the previous six months. One in five specifically listed a Grand Theft Auto game. In fact, among these 12- to 14-year-old girls, the Grand Theft Auto series was second only to The Sims in popularity.”
