The Global Peace Index (GPI) is a measure that ranks countries based on their levels of peace. It evaluates various factors, including levels of violence, conflict, and incarceration rates, to provide a comprehensive overview of how peaceful a nation is. The GPI is published annually by the Institute for Economics and Peace (IEP) and is widely used by policymakers, researchers, and organizations to understand global peace trends. The index uses a scale from 1 to 5, where lower scores indicate higher levels of peace. Countries are assessed on indicators such as military expenditure, political stability, and the presence of organized crime. The GPI aims to promote awareness of peace and encourage efforts to reduce violence and conflict worldwide.
