Nigeria carries a composite country risk of 79.5 out of 100 — the high band, rank 2 of 50 countries in the Tieron reference catalog. Below: the four published indices behind that number with their weights, and what the composite becomes once it is combined with each of 33 manufacturing sectors.
| Factor | Published value | Risk | Weight | Source |
|---|---|---|---|---|
| Labour rights violation | ITUC rating 5 (1 best – 5+ worst) | 100.0 | 0.35 | ITUC Global Rights Index 2025 |
| Public-sector corruption | CPI 26 of 100 (higher = cleaner) | 74.0 | 0.25 | Transparency International CPI 2024 |
| Environmental performance | EPI 37.9 of 100 (higher = better) | 62.1 | 0.20 | Yale EPI 2024 |
| Rule of law | WGI -0.89 (−2.5 … 2.5) | 67.8 | 0.20 | World Bank WGI 2023 |
INFORM Risk layers, 0–10. Continuity rather than compliance: these drive site-level disruption risk once a supplier site has a location.
| Layer | Value (0–10) | Relative |
|---|---|---|
| INFORM Risk (overall) | 6.8 | |
| Natural hazard | 4.8 | |
| Earthquake | 0.1 | |
| Flood | 8.2 | |
| Cyclone | 0.0 | |
| Drought | 3.1 |
Country composite combined with each sector’s process risk, riskiest first.
