In a world where conflicts and tensions seem to dominate headlines, how do we measure something as complex as peace? It’s not just the absence of war or violence-peace is multifaceted, encompassing societal safety, international relations, and military preparedness. This is where the Global Peace Index comes in, offering a comprehensive framework to understand and compare the peacefulness of nations across the globe.

What exactly is the Global Peace Index?
The Global Peace Index (GPI) is the world’s leading measure of global peacefulness, produced annually since 2007 by the Institute for Economics and Peace (IEP), an international think tank dedicated to quantifying peace and its economic benefits. The index was conceived by Steve Killelea, an Australian technology entrepreneur and philanthropist, who recognized the need for a data-driven approach to understanding peace.
What makes the GPI particularly valuable is its scope and rigor. The index ranks 163 independent states and territories according to their level of peacefulness, covering an impressive 99.7 percent of the world’s population. This comprehensive coverage ensures that the index provides a truly global perspective on peace, leaving virtually no corner of the world unexamined.
How does the GPI measure peace?
The beauty of the GPI lies in its systematic approach. Rather than relying on subjective assessments, the index uses 23 qualitative and quantitative indicators from highly respected sources to compile a comprehensive picture of each nation’s peacefulness. These indicators are carefully selected and reviewed annually by an international panel of peace experts from various peace institutes and think tanks, with data collected by the Economist Intelligence Unit.
Think of these 23 indicators as different lenses through which we view peace. Some examine violent crime rates and homicides, while others look at the impact of terrorism or the number of refugees and internally displaced persons. Still others assess military expenditure, weapons imports and exports, or a nation’s participation in UN peacekeeping missions. Each indicator is scored on a scale of one to five and then normalized, allowing for meaningful comparisons across countries.
The three domains of peace
To make sense of these 23 indicators, the GPI organizes them into three broad domains that capture different aspects of peacefulness. The first domain, Ongoing Domestic and International Conflict, uses six indicators to investigate the extent to which countries are involved in internal and external conflicts. This domain examines not just whether conflicts exist, but also their intensity, duration, and the number of deaths they cause. For instance, it tracks both battle deaths from internal organized conflict and deaths from external conflicts.
The second domain, Societal Safety and Security, comprises eleven indicators that evaluate the level of harmony or discord within a nation. The assertion is that low crime rates, minimal terrorist activity and violent demonstrations, harmonious relations with neighboring countries, a stable political scene and a small proportion of the population being internally displaced can be equated with peacefulness. This domain captures the everyday security that citizens experience-whether they fear walking in their neighborhoods, whether their government is stable, and whether they live in harmony with neighboring nations.
The third domain, Militarisation, uses six indicators to reflect the link between a country’s level of military build-up and access to weapons and its level of peacefulness. This includes measuring military expenditure as a percentage of GDP, the number of armed service personnel per capita, and the availability of weapons. Interestingly, it also considers positive contributions, such as financial support for UN peacekeeping missions and nuclear disarmament efforts.
What makes a region peaceful?
When we look at what the GPI reveals about peaceful regions, certain patterns emerge. According to the index’s findings over the years, peaceful regions tend to share several key characteristics. Low crime rates are fundamental-when people feel safe in their daily lives, it creates a foundation for broader societal peace. This extends beyond just violent crime to include perceptions of criminality and the effectiveness of law enforcement.
Another critical factor is minimal terrorist activity and peaceful demonstrations. While protests and dissent are healthy parts of democratic societies, violent demonstrations signal deeper societal tensions. Peaceful regions typically see their citizens expressing disagreement through non-violent means, reflecting mature civic institutions and respect for diverse viewpoints.
Harmonious relationships with neighboring countries cannot be overstated. Nations that maintain positive diplomatic relations, engage in cooperative trade agreements, and resolve disputes through dialogue rather than threats create stable regional environments. Think about the European Union-despite its challenges, the framework for cooperation among member states has helped maintain one of the most peaceful regions in the world.
A stable political environment is equally crucial. This doesn’t necessarily mean unchanging governments, but rather the presence of strong institutions, respect for democratic processes, and smooth transitions of power. When citizens trust that political changes will happen through legitimate channels rather than coups or violence, it contributes significantly to overall peacefulness.
Finally, low internal displacement serves as an important indicator. When large proportions of a population are refugees or internally displaced persons, it typically signals serious underlying problems-whether conflict, persecution, or governance failures. Conversely, regions where people can remain in their homes and communities tend to be more peaceful and stable.
Current global peace trends
The GPI doesn’t just provide a static snapshot-it reveals concerning trends over time. The most recent reports show that global peacefulness has deteriorated for the 13th time in the last 17 years, with the world becoming increasingly fragmented. There are currently 59 active state-based conflicts worldwide-the highest number since the end of World War II.
What’s particularly worrying is that conflicts are becoming more internationalized. Rather than remaining contained within borders, modern conflicts draw in multiple countries through various forms of involvement, making resolution more complex. Additionally, the nearly two-decade trend of falling militarization has reversed, with many countries increasing their military spending and capabilities.
However, it’s not all negative news. Some indicators show improvement, particularly in areas like homicide rates and perceptions of criminality in certain regions. The GPI helps us see both where progress is being made and where urgent attention is needed.
Why the GPI matters for public economics
Understanding peace through the GPI framework has profound implications for public economics. The economic impact of violence is staggering-recent calculations show it represents a significant percentage of global GDP. When governments must allocate resources to managing conflict, maintaining large militaries, or dealing with displaced populations, those funds cannot be invested in education, healthcare, or infrastructure development.
For policymakers and economists, the GPI provides valuable data for decision-making. It helps identify which interventions might be most effective, where resources should be allocated, and how different policy choices impact overall peacefulness. A country that scores poorly on the Societal Safety and Security domain might benefit from investments in community policing and social programs, while one struggling with the Militarisation domain might need diplomatic engagement and arms control agreements.
Moreover, the index helps us understand the relationship between peace and economic development. Countries with higher levels of peace tend to have better economic outcomes, as investors prefer stable environments, trade flourishes in peaceful regions, and human capital can be developed without the disruptions of conflict.
What do you think? Looking at the factors the GPI measures-from crime rates to military spending to relationships with neighbors-which do you think is most important for creating lasting peace? How might your own country or region improve its peacefulness based on these indicators?
