The data maintained by Everytown for Gun Safety also shows that these shootings have occurred throughout the country. In all, 31 states have had an incident of gun violence at a school. Georgia has witnessed far more incidents than others, with 10 happening at schools there since Sandy Hook. There have been seven school shootings in Florida, five in Tennessee, four in North Carolina and four in California.
The majority of the school shootings, 39, have taken place at K-12 schools. The remainder of them have happened at colleges or universities.
Not surprisingly, schools tend to be safer when they are not in session. The longest gap between school shootings appears between mid-June and mid-August of 2013, which falls during summer break, when the majority of students are not enrolled in classes. Other gaps of weeks or longer fall during periods when schools are typically on winter, spring or summer breaks.
