Nathan Gorenstein, Barbara Boyer and Rose Ciotta of the Philadelphia Inquirer summarized shootings in the city last year: "On average, more than four people a day were struck by bullets. About one in six died. On one day alone - Oct. 22 - 19 people were shot, one fatally. It's a toll of injury and death that falls most heavily on the same few neighborhoods year after year: North Philadelphia. West Philadelphia north of Market Street. The southwestern edge of South Philadelphia." During the past four years, half of all shooting victims were under 25, and most of those were African American males. An interactive graphic displaying shooting victims per square mile is included.
