The 2012 United States Peace Index (USPI) has found that the U.S. is more peaceful now than at any other time over the last twenty years.
The second annual edition of the index, produced by Institute for Economics and Peace, provides a comprehensive analysis of peacefulness at the state and city levels, as well as an analysis of the costs associated with violence and the socio-economic measures associated with peace.
The USPI measures peacefulness according to five indicators: the number of homicides, number of violent crimes, the incarceration rate, number of police employees and the availability of small arms.
It is the only statistical analysis of crime, and the cost of crime, in all 50 states and, for the first time this year, the 61 most populous metropolitan areas.
- 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.
