| 1 The data from 1999–2000 onward are subject to change until interviews with school and law enforcement officials have been completed. The details learned during the interviews can occasionally change the classification of a case. For more information on this survey, please see appendix A. |
| NOTE: A school-associated violent death is defined as "a homicide, suicide, or legal intervention (involving a law enforcement officer), in which the fatal injury occurred on the campus of a functioning elementary or secondary school in the United States" while the victim was on the way to or from regular sessions at school or while the victim was attending or traveling to or from an official school-sponsored event. Victims include students, staff members, and others who are not students. Estimates were revised and may differ from previously published data. |
