Children in New York and northern New Jersey are some of the more than 320 U.S. children who died in accidental shootings during a 2 ½ year period examined by The Associated Press and the USA TODAY Network.

The investigation of more than 1,000 accidental shootings of children under age 18 between Jan. 1, 2014 to June 30 of this year found that kids were most likely to be shot accidentally in states with a vibrant gun culture, especially the Deep South.

But children died in the Northeast, too, including in states with some of the toughest rules on gun ownership.

Most died in their own homes, often while playing with friends. Victims were most likely to be either very young children or teenagers.
