Vision for Humanity has compiled the Global Peace Index (GPI) for 2012. The GPI is a composite index that measures the peacefulness of countries around the world. It considers 23 weighted quantitative and qualitative indicators such as perceived criminality in society, access to weapons, imports of weapons, military expenditure, homicides, political instability, jailed population, weapons exports, violent crime, among others.
The lower the score, the more peaceful the nation. I that context, the most peaceful country is Iceland, followed by Denmark, New Zealand, Canada and Japan. On the other end of the spectrum, the least peaceful country is Somalia, followed by Afghanistan, Sudan, Iraq and the Democratic Republic of Congo.
