Whenever I see a researcher or lawyer put a dollar figure on a certain act, I’m always curious how they calculate this figure. Here is another example: a sociologist at Iowa State argues the total monetary cost of a single murder is just over $17 million.

Matt DeLisi, an ISU associate professor of sociology and director of the criminal justice program, led a team of five Iowa State graduate students on the study of 654 convicted and incarcerated murderers. Expanding upon earlier monetization estimates, they calculated the costs of five crimes — murder, rape, armed robbery, aggravated assault and burglary — in terms of the victim costs, criminal justice system costs, lost productivity estimates for both the victim and the criminal, and estimates on the public’s resulting willingness to pay to prevent future violence.

The sociologist argues this calculation was undertaken with crime prevention in mind:

“This area of research has really been run with prevention researchers,” he said. “That’s because what they find is that even if a prevention program is very expensive — and most of them are actually shockingly inexpensive — they’re still more cost effective than allowing these careers to unfold.”

Of course, focusing on prevention can be difficult and it may not eliminate all the crimes. But faced with the high costs of dealing with crimes after they are committed, some may take a longer look at preventative measures.
