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.

Food import burden

9809.0%

Food imports as a percentage of merchandise exports. Source observations are three-year averages; 100% is the scoring saturation threshold.

Production concentration

7,404

Concentration of domestic production by tonnes. Heavy products can dominate this provisional measure.

Climate exposure

0.593

Normalized cereal-yield and population projections. This projection-based component is largely constant over the study window, not annual weather.

Adaptive capacity

0.630

ND-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
62.6%
Can exceed 100% for processing or re-export hubs.
Net import dependency
60.6%
Imports minus exports, relative to domestic supply; negative for net exporters.
Self-sufficiency ratio
39.4%
Basket-weighted domestic production relative to supply.
Calorie coverage
53.7%
Share of basket calories with usable dependency ratios; standalone IDR ranking requires at least 80%.
