This is the ninth edition of the Global Peace Index (GPI), which ranks the nations of the world according to their level of peacefulness. The index is composed of 23 qualitative and quantitative indicators from highly respected sources and ranks 162 independent states, covering 99.6 per cent of the world’s population. The index gauges global peace using three broad themes: the level of safety and security in society, the extent of domestic and international conflict and the degree of militarisation.
In addition to presenting the findings from the 2015 GPI and its eight-year trend analysis, this year’s report provides an updated methodology to account for the economic impact of violence on the global economy. The report also contains a new analysis on Positive Peace and describes its relationship to development and other significant and positive societal outcomes. A detailed thematic analysis of the three aforementioned domains of the GPI is also included.
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.
