A new study shows that deaths and material costs from terrorism have risen sharply worldwide. The study estimates the economic impact of violence on the world economy in 2016 at $14.3 trillion. The Institute for Economics and Peace released the latest Global Peace Index (GPI) last week. The institute is the idea of Australian businessman Steve Killelea. The group says it seeks to develop understanding of social and economic actions that lead to peace. Researchers were asked to study 23 separate indicators to rate levels of peace in 163 countries around the world. All the measures were related to the domestic and international conflict, safety and security, and each nation’s level of militarization.
