Share of population that cannot afford a nutrient adequate diet
What you should know about this indicator
- A nutrient adequate diet meets all essential nutrient requirements, with sufficient diversity and quantity of locally available foods to stay within the upper and lower bounds for total protein, fats, and carbohydrates as well as essential vitamins and minerals required to avoid nutrient deficiencies or toxicity.
- Non-food expenses are estimated by looking at how much low-income people typically spend on things like housing, clothing, and transportation.
- This amount is calculated as the average share of non-food expenditure for a low-income consumer, multiplied by the international poverty line.
- The average share of non-food expenditure is based on the spending habits of specific income groups (quintiles):
- In upper-middle-income and high-income countries, the first quintile of consumers is considered (the poorest 20% of consumers), where people spend around 54% of their income on non-food needs.
- In low-income and lower-middle-income countries, the second quintile is considered (the second lowest 20% of consumers), where people spend about 37% and 44% of their income on non-food needs, respectively.
- The international poverty lines (in international-$ at 2017 prices) are:
- For low-income countries: $2.15/day.
- For lower-middle-income countries: $3.65/day.
- For upper-middle-income countries: $6.85/day.
- For high-income countries: $24.36/day.
- A value of zero indicates a null or a small number rounded down at the current precision level.
