Strategic Vulnerability Index

A transparent, reproducible composite index measuring West African states’ exposure to destabilisation risks. Ranking, method, weights and limitations.

The Strategic Vulnerability Index (SVI) measures, on a 0 to 100 scale, a West African state’s exposure to destabilisation risks. The higher the score, the greater the vulnerability. It does not predict a crisis: it signals a structural fragility that makes a shock more likely and more costly.

It relies solely on public World Bank data, using a published and reproducible method: anyone can check the calculations, challenge the weighting choices and measure their effect on the ranking.

Ranking

Rank 1 = most vulnerable country. The “Robustness” column shows the extreme ranks obtained with the three alternative weightings described below.

Robustness: 11 countries out of 18 keep their rank within two places, whichever weighting is used.

Components and weights

ComponentWeightMeasureSourceNormalisation (0 to 100)
Institutional fragility35 %Government effectiveness, rule of law, control of corruption (average)Worldwide Governance Indicators(2.5 − estimate) ÷ 5 × 100
Political instability and violence25 %Political stability and absence of violenceWorldwide Governance Indicators(2.5 − estimate) ÷ 5 × 100
Armed violence20 %Battle-related deathsUCDP (via Banque mondiale)log(1 + deaths) ÷ log(10,001) × 100, capped at 100; no recorded conflict = 0
Neighbourhood exposure10 %Share of land neighbours within the perimeter with at least 25 battle-related deathsUCDP (via Banque mondiale)affected neighbours ÷ neighbours × 100
Economic fragility10 %GDP per capita (60%) and inflation (40%)World Development IndicatorsGDP: log scale between $300 and $10,000; inflation: 0 to 30%

Final score: weighted average of available components. If a component is missing, the remaining weights are rescaled; no score is computed if less than 60% of total weight is available. For violence, neighbourhood and economy, the latest known value is carried forward for up to two years.

Vulnerability classes

  • Moderate < 40
  • Notable 40 – 50
  • High 50 – 60
  • Very high 60 – 70
  • Critical ≥ 70

Sensitivity analysis

Any weighting is a choice. To measure its effect, the index is recomputed with three alternative weight sets: equal weighting (20% each); security priority (institutions 20%, stability 30%, violence 30%, neighbourhood 15%, economy 5%); governance priority (institutions 45%, stability 25%, violence 15%, neighbourhood 5%, economy 10%). The ranking’s “Robustness” column shows the result.

Limitations

  • Governance indicators (WGI) aggregate expert and survey perceptions; they carry margins of error and react with a lag.
  • World Bank data is published with a one to two-year lag: the index describes a recent situation, not breaking news.
  • Neighbours outside the perimeter (notably Algeria, Libya, Sudan, Central African Republic) are not measured, which underestimates the neighbourhood exposure of Chad, Niger, Mali and Cameroon.
  • Battle-related deaths only cover conflicts reaching the UCDP threshold; lower-intensity criminal or intercommunal violence is not captured.
  • The index is an analytical aid, not a judgement on states or their populations.
