And yet the overall rates of child sex crimes and of teen sex are down since the 1990s, as are juvenile crime, school violence and teen fighting. David Finkelhor, director of the Crimes Against Children Research Center at the University of New Hampshire, calls this distance between anxiety and reality ''juvenoia'' and chalks it up to an ''exaggerated fear about the influence of social change on children.''
