Our Data Explorers on Armed Conflict and War

Measuring how common and deadly armed conflicts are across the world helps us understand how people’s lives and livelihoods are affected by large-scale violence.

To make related data easier to access and understand, we have created two detailed Data Explorers.

We designed them for people who want to take a closer look at the data. People who are more interested in the key insights and most important charts can find those on our War and Peace topic page and smaller Countries in Conflict Data Explorer.

The first Data Explorer below is primarily structured around types of conflicts. It provides data on all armed conflicts, all state-based conflicts, as well as interstate, intrastate, extrastate, non-state conflicts, and one-sided violence.

For these types of conflicts, we provide data on how deadly and common they are, which countries are involved, and where they take place. You can read more about these different measures in our article about them.

The second Data Explorer uses the same data, but lets you browse the data primarily based on your choice of five data sources:

• Uppsala Conflict Data Program (UCDP)[1]
• Project Mars by Jason Lyall (2022)[2]
• Militarized Interstate Events by Douglas Gibler and Steven Miller[3]
• Correlates of War (CoW)[4]
• Peace Research Institute Oslo (PRIO)[5]

You can learn more about these sources in our article on them.
