　　Not exactly. New York City, for instance, is safer than its ever been; its ranked 136th in crime among all American cities. Nationwide, stranger kidnaps are extremely rare; theres a one-in-a-million chance a child will be taken by a stranger, according to the Justice Department. And 90 percent of sexual abuse cases are committed by someone the child knows. Mortality rates from all causes, including disease and accidents, for American children are lower now than they were 25 years ago. According to Child Trends, a nonprofit research group, between 1980 and 2003 death rates dropped by 44 percent for children aged 5 to 14 and 32 percent for teens aged 15 to 19.

　　Then theres the whole question of whether modern parents are more watchful and nervous about safety than previous generations. Yes, some are. Part of the problem is that with wall-to-wall Internet and cable news, every missing child case gets so much airtime that its not surprising even normal parental anxiety can be amplified. And many middle-class parents have gotten used to managing their childrens time and shuttling them to various enriching activities, so the idea of letting them out on their own can seem like a risk. Back in 1972, when many of todays parents were kids, 87 percent of children who lived within a mile of school walked or biked every day. But today, the Centers for Disease Control report that only 13 percent of children bike, walk or otherwise get themselves to school.
