The Global Peace Index, an initiative of Institute for Economics and Peace (IEP), provides a ranking for each nation in regards to their peacefulness.

It uses 23 different qualitative and quantitative indicators under three broad themes: the level of safety and security in society, the extent of domestic and international conflict and the degree of militarisation. The index includes a detailed 127 page report and a website with an interactive map that allows the user to click on specific countries and look at how well they are doing against the indicators.


Last year the global GPI score remained stable. However, while the average level of global peacefulness was stable, a number of indicators and countries did deteriorate while others improved. Four out of the nine geographical regions experienced an improvement in peace: Europe, North America, sub-Saharan Africa and Central America and the Caribbean. The other five regions became less peaceful. The most substantial changes in the Index occurred in the Middle East and North Africa (MENA) where several countries suffered from an upsurge in violence related to sectarian strife and civil conflicts, resulting in the region being ranked as the least peaceful in the world.

The societal safety and security domain improved slightly last year, driven by falls in the homicide rate and the likelihood of violent demonstrations. The improvements in homicide rates mainly reflected data updates in some high homicide countries. This improvement was counterbalanced by deteriorations in the ongoing conflict and militarisation domains, owing to increases in deaths from internal conflict, non-payment of UN peacekeeping dues, and a continuing deterioration in the impact of terrorism indicator.
