The small city of Wilmington, Del., is known for big banks and Fortune 500 firms, not teenage shootings. But the Associated Press and USA TODAY Network discovered through a data analysis that the city leads the country dramatically in its rate of shootings among people younger than 18. The rate there is nearly double Chicago’s.

Most of the cities with the highest rates of teen shootings were not metropolises like Baltimore or Los Angeles; most of them had populations less than 250,000 people.
