Shock, frustration, and rage. That’s our reaction to the hate-filled video record that Elliot Rodger left behind. The 22-year-old, believed to have killed 6 people in Santa Barbara last night, left behind a terrible internet trail.

I cannot and will not speculate about the “mind of the killer” in such cases, but I can offer a little perspective on the nature and social context of these acts. This sometimes entails showing how mass shootings (or school shootings) remain quite rare, or that crime rates have plummeted in the past 20 years. I won’t repeat those reassurances here, but will instead address the bald-faced misogyny and malice of the videos. It outrages us to see a person look into a camera and clearly state his hatred of women — and then, apparently, to make good on his dark promises. It also raises other awful questions. Are these sentiments generally held? If you scratch the surface, are there legions of others who would and could pursue “retribution” as Mr. Rodger did? Is serious violence against women on the rise?

Probably not. Rates of sexual violence in the United States, whether measured by arrest or victimization, have declined by over 50 percent over the last twenty years. As the figure shows, the rape and sexual assault victimization rate dropped  from over 4 per 1000 (age 12 and older) in 1993 to about 1.3 per 1000 in 2012.  And, if you add up all the intimate partner violence (including all rape, sexual assault, robbery, and aggravated assault committed by spouses, boyfriends, or girlfriends), the rate has dropped from almost 10 per 1000 in 1994 to 3.2 per 1000 in 2012. The numbers below include male victims, but the story remains quite consistent when the analysis is limited to female victims.

Of course, misogyny and violence against women remain enormous social problems — on our college campuses and in the larger society. Moreover, the data at our disposal are often problematic and the recent trend is far less impressive than the big drop from 1993 to 2000. All that said, “retribution” videos and PUA threads shouldn’t obscure a basic social fact:  22-year-olds today are significantly less violent than 22-year-olds a generation ago.
