The Atlantic has a fun guess-the-homicide-rate-over-time game!
Turns out I'm really good at this game.
But I shouldn't boast; I have no excuse not to do well. I show this chart literally half a dozen times in each and every class I teach.
What I don't like is how dismissive they are of the current increase in violence, the largest percentage increase in homicide in decades. They quote the Brennan Center, which has been bending over backwards to downplay the recent increase in killing. (Lest there be any evidence of an effect whose name shall not be spoke.... You know, the one that starts with F, son.) The Center wants us to see those dead bodies not as real lives who mattered, but statistical flukes.
