Falling crime rates in the U.S. are due in part to mass incarceration
For[edit | edit source]
- Academic Steven Levitt says in a 2004 paper, "Using an estimate of the elasticity of crime with respect to punishment of .30 for homicide and violent crime and .20 for property crime, the increase in incarceration over the 1990s can account for a reduction in crime of approximately 12 percent for the first two categories and 8 percent for property crime, or about one-third of the observed decline in crime."

- According to an article from the Guardian, "Researchers at the Brennan Center for Justice placed crime statistics from all 50 states over the past four decades against 13 other potential explainers of crime reduction, including decreases in alcohol consumption, growth in income and data-driven policing techniques. The conclusion was that the sharp increase in prison numbers has had a negligible effect on the downward trend in crime, with mass incarceration responsible for around 6% of property crime reduction in the 1990s and less than a single percentage point in the 2000s."
