(AP) – An investigation by The Associated Press and USA TODAY Network reveals that the highest rates of teenage gun violence in the country are generally in smaller and mid-sized cities.

Wilmington, Delaware, with a population of just 72,000, has by far the highest rates of young people ages 12 to 17 injured or killed in shootings.

Of the top 10 cities with the highest rates, most were smaller cities with populations between 50,000 and 250,000. High on the list were Syracuse, New York, and Savannah, Georgia. Chicago was the lone large-population city ranking high.

Poverty and a sense of hopelessness is a common thread.
