The Global Peace Index (GPI) is a report produced by the Australia-based NGO Institute for Economics & Peace (IEP) which measures the relative position of nations' and regions' peacefulness.[2] The GPI ranks 163 independent states and territories (collectively accounting for 99.7 per cent of the world's population) according to their levels of peacefulness.
The 2025 GPI indicates Iceland, Ireland, New Zealand, Austria, Switzerland, Singapore, Portugal, Denmark, Slovenia, Finland, the Czech Republic, and Japan to be the most peaceful countries, and Russia, Ukraine, Sudan, the Democratic Republic of the Congo, Yemen, Afghanistan, Syria, South Sudan, Israel, Mali, Myanmar, Burkina Faso, Somalia, the Central African Republic, and North Korea to be the least peaceful.
In 2017, 23 indicators were used to establish peacefulness scores for each country. The indicators were originally selected with the assistance of an expert panel in 2007 and are reviewed by the expert panel on an annual basis.
An additional aim of the GPI database is to facilitate deeper study of the concept of positive peace, or those attitudes, institutions, and structures that drive peacefulness in society. The GPI also examines relationships between peace and reliable international measures, including democracy and transparency, education and material well-being. As such, it seeks to understand the relative importance of a range of potential determinants, or "drivers", which may influence the nurturing of peaceful societies, both internally and externally.[
Researchers have determined that Positive Peace, which includes the attitudes, institutions, and structures that pre-empt conflict and facilitate functional societies, is the main driver of peace. The eight pillars of positive peace are well-functioning government, sound business environment, acceptance of the rights of others, good relations with neighbours, free flow of information, high levels of human capital, low levels of corruption, and equitable distribution of resources.
