CNN — Some staggering numbers, from a new study on gun violence affecting school-age children in the U.S.
The study says close to 39-thousand American kids were killed by guns between 1999 and 2017.
The research, conducted by Florida Atlantic University, accounted for children between five and 18-years-old.
A senior author of the study says more school-age children die from guns than on-duty police officers or military members.
The study found that of the deaths, 86-percent involved boys.
Black children accounted for 41-percent of those killed.
The study will be published in the American Journal of Medicine.
