How the score is calculated
The score starts at 8. It adds points from recorded affected, deaths, displaced and casualty counts, plus terms found in the story title, event type or status. For each count, only its highest matching band is used.
- Affected people
- 1–999: +5 · 1,000–9,999: +12 · 10,000–99,999: +20 · 100,000–999,999: +28 · 1 million+: +35
- Deaths
- 1–9: +8 · 10–99: +14 · 100–999: +22 · 1,000+: +30
- Displaced people
- 1–9,999: +6 · 10,000–99,999: +12 · 100,000+: +18
- Casualties
- 100 or more: +8
- Story wording
- +10 for terms such as catastrophe, famine, war, conflict, major earthquake, mass casualty or critical. Otherwise, +5 for active, ongoing, emergency, outbreak, cyclone or hurricane.
Score bands: Watch 0–24 · Moderate 25–49 · High 50–74 · Critical 75–100. Scores are capped at 100. Missing or unparseable figures add no points.
