What the threat reading is made of
| Conflict | 0 |
|---|---|
| Unrest | 0 |
| Security | 0 |
| Spillover from neighbours | 10 |
| Natural hazard | 50 |
| Resilience | 76 |
Each is 0 to 100. Resilience runs the other way to the rest: a high number is a country better able to absorb a shock, not a country in more trouble.
