The results of the Global Peace Index (GPI) for 2010 suggest that the world has become slightly less peaceful in the past year. The GPI, which gauges ongoing domestic and international conflict, safety and security in society and militarisation in 149 countries, registered overall increases in several indicators, including the likelihood of violent demonstrations and perceptions of criminality. In some nations, an intensification of conflicts and growing instability appears to be linked to the global economic downturn in late 2008 and early 2009. This is the fourth edition of the Global Peace Index (GPI). It has been expanded to rank 149 independent states and updated with the latest-available figures and information for 2008-09. The index is composed of 23 qualitative and quantitative indicators from respected sources, which combine internal and external factors ranging from a nation's level of military expenditure to its relations with neighbouring countries and the level of respect for human rights.
