Simple request for stats like I've asked for how many times now? Literally how many times have you ducked this?
This may or may not be surprising, but nobody is publishing this data. This is in large part because there are no clear definitions.
CHDS kept a database, but they apparently stopped adding data after Uvalde. Also, their database included things like pellet guns ... pumping numbers to try and make things look worse than they are.
Examples - Does "School" include colleges? Do we include incidents at 2 AM on a weekend? What constitutes "mass shooting"?
Also, I'm not clear what data is wanted ... number of students killed? Total deaths? Number of shootings regardless of any deaths? Do sporting events and arguments count? How far back?
For overall reference, there have been a total of 115 shootings (including those with zero deaths) at schools of all sorts (including colleges) of the nature we think of them as popularized by the media in 58 years of data.
Sticking with the FBI's usual definition of "4+" for "Mass Shooting" (not necessarily 4 dead), and looking at post-covid, I can find this:
2021: Ethan Crumbley killed 4 students at Oxford High School in November.
2022: Uvalde was BY FAR the deadliest incident, with Salvador Ramos killing 21 people (19 kids, 2 teachers). Ramos killed more students than all school "mass shootings" in 2023 combined all by himself. In fact, this was the 2nd deadliest school shooting in US history. The last shooter before him, and after Ethan, was Raymond Spencer, he was also Hispanic.
2023 had a total of 3 incidents, with the deadliest mass school shooting committed by Audrey Hale, a woman (Covenant School). She killed 6 people, 3 kids and 3 adults. 7th deadliest ever. (Everyone remembers, this is the one where her manifesto can not be released because ... well, I have no idea how an investigation can be ongoing this long, but apparently it is. Or so it is claimed.)
Huguenot High School had 7 people killed at a graduation ceremony. The killers were black males.
Westinghouse Academy had 4 shot (0 dead). A black male shooter.
I can start gathering data on 2024, but I don't think this list is shaping up the way you imagined it would ...
6 incidents
1 White Male
1 White Female
2 Hispanic Male
2 Black Male
