One thing I haven't seen anywhere is, how many people die in a normal year's Hajj? Obviously this is higher, but it's said to be over a million people, and so I have to think some people die every year. Is this 10x the normal amount? 100x?
From what I can find there are no steady numbers. In 2023 there were 500 recorded deaths, but there's a suspicion that the numbers are higher (much as with this year). Famously in 2015 2000+ people died in a single crowd-crush event.
It's a dangerous thing, but worry not, Muslims believe that to die on Hajj is to be martyred, and sent straight to paradise, which no doubt contributes somewhat to lax safety standards.
