The Global Peace Index (GPI) is a report produced by the Australia-based NGO Institute for Economics & Peace (IEP) which measures the relative position of nations' and regions' peacefulness. The GPI ranks 163 independent states and territories (collectively accounting for 99.7 per cent of the world's population) according to their levels of peacefulness. In the past decade, the GPI has presented trends of increased global violence and less peacefulness.
The GPI (Global Peace Index) is developed in consultation with an international panel of peace experts from peace institutes and think tanks with data collected by the Economist Intelligence Unit. The Index was first launched in 2007, with subsequent reports being released annually. In 2015 it ranked 165 countries, up from 121 in 2007. The study was conceived by Australian technology entrepreneur Steve Killelea, and is endorsed by individuals such as former UN Secretary-General Kofi Annan, the Dalai Lama, and 2008 Nobel Peace Prize laureate Martti Ahtisaari. The updated index is released each year at events in London, Washington, D.C., and at the United Nations Secretariat in New York City.
