Ridiculously strong negative correlation between U.S. homicide and suicide rates, 2001-2013

Seriously?


This is U.S. data on suicides and homicides from 2001 to 2013. The correlation between those two lines is -.96! It's an almost perfect negative correlation. Homicide rate is dropping, hurrah! But suicide rate is climbing, as if compensating for the decline in homicides. The suicide rate increased 18% just as the homicide rate dropped by 20%.


Could those psychodynamic guys have been onto something?
