Crime in the three biggest American cities (NY, Chicago, LA) is down…and up almost everywhere else. In part, this is due to the aging of the population in those cities. “Together they lost more than 200,000 15-to 24-year-olds between 2000 and 2005. That bodes ill for their creativity and future competitiveness, but it is good news for the police. Young people are not just more likely to commit crimes. Thanks to their habit of walking around at night and their taste for portable electronic gizmos, they are also more likely to become its targets.” Young people, your gizmos are hurting America!
