Policy makers, take note.
The Institute for Economics and Peace (IEP), dedicated to developing metrics to analyse peace and to quantify its economic benefits, has created the Global Peace Index (GPI) to measure the national peacefulness. 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 militarization.  These factors are both internal such as levels of violence and crime within the country and external such as military expenditure and wars.
The GPI is composed of 23 qualitative and quantitative indicators from highly recognized sources, covering 99.7 per cent of the world’s population, and it has been estimated since 2008.[Source: Ramon Martinez – Health Intelligence ]
