1. What is the Global Hunger Index (GHI)?

Definition: The GHI is a tool designed to comprehensively measure and track hunger at global, regional, and national levels.

Purpose: It provides a way to compare levels of hunger between countries and regions and to raise awareness of hunger issues worldwide.

2. How Does the GHI Calculator Work?

The calculator uses the formula:

Where:

• \( GHI \) — Global Hunger Index score
• \( U \) — Undernourishment (% of population)
• \( CW \) — Child Wasting (% of children under 5)
• \( CS \) — Child Stunting (% of children under 5)
• \( CM \) — Child Mortality (% of children under 5)

Explanation: The GHI combines four component indicators into one index score, giving equal weight to each indicator.

3. Importance of GHI Calculation

Details: The GHI helps policymakers and organizations understand hunger severity, track progress, and allocate resources effectively to combat hunger.

4. Using the Calculator

Tips: Enter the percentage values for all four indicators. All values must be ≥ 0. The calculator will compute the average (GHI score).

5. Frequently Asked Questions (FAQ)

Q1: What do the GHI scores mean?
A: GHI scores are categorized as: ≤9.9 (low), 10-19.9 (moderate), 20-34.9 (serious), 35-49.9 (alarming), ≥50 (extremely alarming).

Q2: Why are all four components equally weighted?
A: Equal weighting ensures a comprehensive view of hunger, capturing both current (wasting) and chronic (stunting) malnutrition.

Q3: Where can I find official GHI data?
A: The International Food Policy Research Institute (IFPRI) publishes annual GHI reports with country-level data.

Q4: How often is GHI calculated?
A: The global GHI is typically updated annually, though some country data may be less frequent.

Q5: What are limitations of the GHI?
A: The GHI doesn't capture micronutrient deficiencies or seasonal variations in hunger, and relies on available national data.
