The index consists of different indicators for internal and external peace (weighting: 60 to 40 percent). The lower the index value, the higher the peacefulness.
Iceland was the most peaceful country in the world in 2025 with an index value of 1.1. Ireland, New Zealand, and Austria followed behind.
What is the Global Peace Index?
The Global Peace Index is an effort by the Institute for Economics and Peace to measure the degree of peacefulness in countries across the world and rank them accordingly. The first list was created in 2007 and has since then been published annually. The index includes a number of indicators relating to both domestic and international peacefulness.
International indicators
In regards to international affairs the majority of indicators relate to involvement in military conflict or the efforts of the state in question to resolve conflict and ensure the safety of those affected. For example those states that give more financial support to UN peacekeeping missions are considered to be more peaceful while those who have a higher military expenditure as a percentage of gross domestic product (GDP) are considered to be less peaceful. The United States never reached the top 20 of the list, in part due to it having a high level of military spending as a percentage of GDP.
Domestic factors
Domestic indicators focus on both the amount of violence and crime in addition to incarceration rates. Again, the United States fails to reach levels akin to other countries. The country’s incarceration rates are significantly higher than in other OEDC countries. Moreover, the number of deaths from gun violence also contributes to the relatively low peacefulness ranking of the United States.
