We're 21 weeks into 2018, and there have already been 23 school shootings where someone was hurt or killed. That averages out to more than 1 shooting a week.

The parameters CNN followed in this count are:
  • A shooting that involved at least one person being shot (not including the shooter)
  • A shooting that occurred on school grounds
  • We included grades K through college/university level
  • We included gang violence, fights and domestic violence
  • We included accidental discharge of a firearm as long as the first two parameters are met
