Data from the Food and Agriculture Organization (FAO) represent 3-year averages.
Hunger rates of 2.5% or undernourishment totals of 10000 or lower should be considered minimal approximations rather than precise measurements.
The Global Hunger Index (GHI) compiles the values of four indicators: Undernourishment (1/3), Child Mortality (1/3), Child Stunting (1/6), and Child Wasting (1/6), and places the result on a 100-point scale.
The best possible GHI score is 0 (no hunger) and the worst is 100. Scores from 20-34.9 are considered Serious, 35-49.9 are Alarming, and anything higher Extremely Alarming.
Countries with GHI scores below 5 are collectively assigned an index value of 5, without individual ranks.
2024 data for Burundi, Lesotho, and South Sudan were incomplete. As such, the scores for those nations were given by the original source as provisional ranges rather than a single number: 10-19.9 for Lesotho and 35–49.9 for Burundi and South Sudan. These ranges have been converted to their approximate median values to preserve numerical sorting.
