The table below provides the GPI rankings for the 144 countries analysed in 2009. Rankings for the 140 countries analysed in 2008 and the 121 countries analysed in 2007 are also included. Countries most at peace are ranked first. A lower score indicates a more peaceful country. The index was collated by the Economist Intelligence Unit for a new thinktank called the Institute for Economics and Peace. It uses a weighted mix of 23 criteria, including foreign wars, internal conflicts, respect for human rights, the number of murders, the number of people in jail, the arms trade, and degrees of democracy. This year's results found the economic downturn had made the world a little less peaceful. That, say the authors, "appears to reflect the intensification of violent conflict in some countries and the effects of both the rapidly rising food and fuel prices early in 2008 and the dramatic global economic downturn in the final quarter of the year. "Rapidly rising unemployment, pay freezes and falls in the value of house prices, savings and pensions is causing popular resentment in many countries, with political repercussions that have been registered by the GPI through various indicators measuring safety and security in society." The results come from a groundbreaking study, released alongside the 2009 GPI, which estimates the economic impact of lost peace on the global economy at $7.2tn (£4.4tn) a year. Of this, $4.8tn is made up of business activities that never see the light of day because of violence; a further $2.4tn relates to the redeployment of resources and expenditure away from industries benefiting from violence to those that benefit from peace. "The reality is that the net economic benefit of peace to humanity is substantial, and governments and businesses should seriously consider how adopting practices and policies that promote peace helps their bottom line," said Clyde McConaghy, who oversees the index at the institute. "It is this kind of thinking that the Institute for Economics and Peace will promote."
