(CNN)In the year since a troubled teen gunned down 17 people at Marjory Stoneman Douglas High School, shootings have continued at schools across America.
Since Parkland, by CNN's count, there have been at least 31 incidents at K-12 schools in the United States in which someone was shot. That averages out to a shooting every 11.8 days.
In those shootings 19 people were killed and another 44 were injured.
"School shooting has become a cultural thing in the United States," says Mike Clumpner, president of Threat Suppression, a security consulting company that specializes in active-shooter response.
The parameters CNN followed in this count are:
- Shooting must involve at least one person being shot (not including the shooter)
- Shooting must occur on school property, which includes but is not limited to buildings, fields, parking lots, stadiums and buses
- We included gang violence, fights and domestic violence, but our count is not limited to those categories
- We included the accidental discharge of a firearm as long as the first two parameters are met -- except when the sole shooter is a law enforcement or security officer
As you can see from the map above, the school shootings over the past 12 months touched many regions of the country, although they were rarer in Northern states and the Intermountain West.
They occurred in classrooms, in hallways, in parking lots and on baseball and football fields. The deadliest one since Parkland was in May at a high school in Santa Fe, Texas, where 10 people died -- eight students and two teachers -- after a 17-year-old gunman opened fire in an art class.
The most recent was Tuesday at a high school in Kansas City, Missouri, where a girl was shot and killed in a parking lot during a basketball game.
