Global Peace Index
The Global Peace Index (GPI) is an attempt to measure the relative position of nations' and regions' peacefulness. It is the product of the Institute for Economics and Peace (IEP) and developed in consultation with an international panel of peace experts from peace institutes and think tanks with data collected and collated by the Economist Intelligence Unit. The list was launched in May 2007 and updates have been made on an annual basis since then. It is claimed to be the first study to rank countries around the world according to their peacefulness.
The 2016 index, which analyzed 163 countries and territories, rates Syria the least peaceful country, followed by South Sudan, Iraq, Afghanistan and Somalia. The world’s most peaceful countries are Iceland, Denmark, Austria, New Zealand and Portugal.
