Approach: Memorisation framework for GHI componentsThe Global Hunger Index (GHI) uses the mnemonic
UWSC:
- U -- Undernourishment (% of population with insufficient caloric intake)
- W -- Wasting in children <5 years (weight-for-height <-2 SD)
- S -- Stunting in children <5 years (height-for-age <-2 SD)
- C -- Child mortality (under-5 mortality rate)
The under-5 mortality rate captures deaths from birth through age 4 years 364 days. The
Infant Mortality Rate (IMR) captures only deaths in the first year of life (0-365 days) and is a SUBSET of under-5 mortality, but it is NOT separately listed as a GHI indicator.
The GHI scoring gives equal weight (1/3 each) to: undernourishment, child undernutrition (wasting + stunting averaged), and child mortality.
