These are all known tornadoes resulting in student deaths at primary and secondary schools in the United States from 1865 to 2015.Two high fatality events after 1953 occurred in Mississippi (23 in 1955) and Illinois (13 in 1967); accounting for 82% of 1952–2006 deaths, both from violent class tornadoes.More tornadoes with deaths in schools have occurred in the Southeastern United States—23 events or over half the national total—than any other region.This is probably chiefly due to three reasons: the low population density, greater tornado awareness (and better visibility affording more warning), and the time of year and of day that most tornadoes strike the Great Plains.One school fatality tornado event has occurred in Ohio, Louisiana, Iowa, Colorado, Kansas, South Carolina, Maryland, Virginia, North Carolina, New York (although this event was probably a downburst instead of a tornado), Minnesota, and Florida.
