2012 U.S. Peace Index Shows Continuing Reduction in Violence
Thinking About Corrections


“The last twenty years have seen a substantial and sustained reduction in direct violence in the United States.”

This quote from the Executive Summary is just one highlight of the second annual 2012 United States Peace Index (USPI).  The USPI is produced by the Institute for Economics and Peace (IEP) and provides a comprehensive assessment of U.S. peacefulness at the state and city levels and analysis of the costs associated with violence and the socio-economic measures associated with peace.USPI

Key Findings from the USPI include:

  • Maine is the most peaceful state for the 11th consecutive year, Louisiana least peaceful state.
  • Wyoming has improved the most while Arizona records the biggest fall.
  • Cambridge metro area is the most peaceful, Detroit the least peaceful.
  • The U.S. is more peaceful than at any time in the last 20 years.
  • Further improvements in peacefulness would generate hundreds of billions of extra economic activity.
