Methodology

The Global War Index turns the day's international news coverage into a single, easy-to-read number between 0 and 100 for each type of war risk. Like a fear gauge for markets, it measures how threatening the news feels — not the odds that a war will start.

What we read

Every few hours we collect headlines and summaries from a diverse set of international news outlets and specialist defense, security and nuclear publications. Each story is grouped with other reports of the same event, so a single event covered by many outlets is counted once.

What we look at

Readings are smoothed so that one isolated headline cannot swing an index, while genuinely extreme events can move it quickly.

The scale

The indices

Global War Index
The overall reading, driven most by whichever risks are highest on the day.
Nuclear War
Nuclear threats, strategic force posture, tests, doctrine and incidents around nuclear facilities.
Hybrid War
Cyberattacks, sabotage of infrastructure, state disinformation and coercive economic measures.
Great-Power War
The risk of direct conflict between major military powers.
Civil War
Internal armed conflict, coups, insurgencies and mass political violence.
Biological & Chemical
Use, allegations and programs involving chemical or biological weapons.
Hotspots
Regional readings shown when a region receives sustained coverage.
World map
Each continental region — North America, Central America & Caribbean, South America, Europe (including Russia west of the Urals), Africa, Asia (including Siberia and the Middle East) and Oceania — is scored on the same scale from the events that take place in it or directly threaten it. Regions are shown for context and do not feed the Global War Index.

Limits

The index reflects what the news reports and how it reports it. Coverage can be incomplete, biased or wrong, and quiet but dangerous developments may not register. Treat the index as a barometer of the conversation, not as a prediction.
