The Global Peace Index (GPI), Portugal, at number 13, has also improved slightly, although its recent package of cutbacks will be a test of its social cohesion. The USA is the 85th most peaceful nation, according to the ranking. The Global Peace Index is compiled by the Institute for Economics and Peace, which uses data from the research and predictions department at The Economist. The figures are a compound score based on a variety of factors including national crime rate, security spending, relations with neighboring countries, prison population and human rights record. It is the report’s conclusion that the world is less peaceful now than last year. The development is driven by economic woes which have seen crime rates increase, violent protests in capital cities and more people are becoming victim to violent acts.
