I see World Happiness Report as primarily a measure of what's considered the most socially acceptable way to discuss happiness across cultures. In the USA, people often brag about how miserable they are, for example.
Americas mistakes are not as unique to us as Europeans keep telling themselves.
1,700 people out of ~50 million K-12 students in a 22 year period.
.003352% chance of injury or worse over 22 years. And now I realize the denominator should be bigger because it doesn't count faculty/staff or college students.
There's no reason to live in fear of school shootings. (But there should still be much greater gun control.)
I also think that it's fair to think about other examples of exposure to violence and not just the Parent's example of weekly school shootings. Speaking of gun violence, I'm not sure I know anyone personally in the USA who haven't been impacted by it, whether that's knowing someone who was hurt, having to lock down at work or home, having to drive a different route home because of an active shooting, or just hearing it and then hearing the sirens. Of course, these are not all equal, but it's interesting to think about.
From wikipedia it looks like there's 13,000 school districts in the US - so 1 in 10 (!!!!) has had a school shooting in the last 22 years. Am I doing this right?
But I agree with you that it affects the school and community deeply, even in surrounding communities. I live in Texas, and the whole state was deeply affected after Uvalde. A relative's school got evacuated a few weeks later out of what happened to be a false alarm, with the relative forced to exit the school hands above their head to show they didn't have a gun. They were on the complete other side of the state, probably like a 6 hour drive away.
