Sao Tome and Principe
Higher means more vulnerable. All countries share the same 0–1 scale. Shading shows the range across 20 imputations, not a confidence interval.

The seven indicators in 2023
Bars use direction-adjusted normalized values: longer always means more vulnerable. Values beside titles retain published units; raw and normalized fields may reflect different imputation stages.
Feed import dependency
0.0%Import dependency of the feed basket, weighted by reported feed tonnes.
Food import burden
254.0%Food imports as a percentage of merchandise exports. Source observations are three-year averages; 100% is the scoring saturation threshold.
Supplier concentration
4,224Concentration of import suppliers, aggregated across commodity groups. 10,000 means a single supplier within a group.
Production concentration
1,973Concentration of domestic production by tonnes. Heavy products can dominate this provisional measure.
Climate exposure
0.793Normalized cereal-yield and population projections. This projection-based component is largely constant over the study window, not annual weather.
Adaptive capacity
0.370ND-GAIN readiness. Higher is better: stronger capacity to respond to a shock. Darker shading indicates lower readiness.
Behind the import-dependency figure
The score uses bounded dependency values. These additional measures retain the underlying trade picture.
- Gross dependency, uncapped
- 67.5% Can exceed 100% for processing or re-export hubs.
- Net import dependency
- 53.6% Imports minus exports, relative to domestic supply; negative for net exporters.
- Self-sufficiency ratio
- 46.4% Basket-weighted domestic production relative to supply.
- Calorie coverage
- 93.4% Share of basket calories with usable dependency ratios; standalone IDR ranking requires at least 80%.
