INCIDENT DATA
Preliminary Information on Averted Reports Submitted to Date
National Policing Institute staff, project subject matter experts, and a limited number of individuals directly involved in preventing attacks have developed incident reports shown in the Report Library. 51 incident reports have been developed to date, based largely on open source media reports and court documents on averted school attacks. Reports were developed from incidents selected at random that occurred across the United States between 1999 and 2017, in K-12 schools as well as in colleges and universities. The analysis is preliminary, and it is recognized that the total number of reports represents a small sample size. Question fields are not mutually exclusive, which is why some questions display a total number of answers that is greater than the total number of incidents. Additionally, certain fields were unknown or unable to be answered from open sources, resulting in missing answers for particular questions. Below are preliminary and descriptive findings on aggregate data of the averted incident reports in the system.
This graph illustrates the total number of averted school violence incidents based on the education level. High School overwhelmingly reports higher at 69% while middle school and college come in at 16% and 12% respectively with elementary school reporting 4% of the total averted incidents.
This chart focuses on the percentage of reported averted school violence incidents based on student body size, segmented by K-12 and college. K-12 represent 87% of the reported incidents while college logs 13%. 64% of the total number of reports are from K-12 schools between 500-2000 students.
This graph breaks down the incident reports based on the total number of suspected assailants. 1 suspect is reported 59% of the time while 2 suspects represent 24% of the averted violence reports.
This graph reflects the number of reports based on the school security measures provided. 30% of all averted school violence reporting schools have security officers at or in the school. 15% of ASV reports are from schools that utilize video cameras to monitor hallways.
This chart illustrates the total number of averted school violence incidents based geographical area. Suburban areas report 69% of the averted violence incidents while rural and urban come in at 26% and 6% respectively.
