Below, I've posted the graph that was included in the article. Note a few things:
1. Traffic deaths are essentially level from through 2006, then have declined steadily. Presumably this comes from safer cars???
2. Drug deaths increased steadily as abuse may have increased and the number of prescriptions of heavy narcotics may have increased. I wonder if the increase corresponds to similar increases in the number of prescriptions. This would directly correspond to accidental deaths from teens taking parents drugs, etc... Note that the prescription drug death red line has remained steady since 2006 and more recently declined.
3. We are really fucking good (and steady) at firearm deaths in the US.
