The 2012 United States Peace Index (USPI) finds that the US is more peaceful now than at any other time over the last twenty years. This edition 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.
