Global Peace Index (Institute for Economics and Peace) – The GPI ranks states and territories based on the level of peacefulness. It does so by using qualitative and quantitative indicators to measure the state of peace under three thematic domains: level of Societal Safety and Security; the extent of Ongoing Domestic and International Conflict; and the degree of Militarisation.
The GPI studies the relationship between actual peace in the country and the concept of positive peace, i.e. the attitudes and institutional structure necessary for peaceful societies. The index shows how the deficit in positive peace is often an indicator of future increase in violent conflict and how an increase in positive peace can have positive economic outcomes.
