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 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.
Share of population that cannot afford a nutrient adequate diet
Percentage of the total population unable to afford a nutrient adequate diet. A diet is considered unaffordable when the diet cost plus expenditures for basic non-food needs exceed income per capita per day.

Sources and processing

This data is based on the following sources

Food Prices for Nutrition provides indicators on the cost and affordability of healthy diets in each country, showing the population's physical and economic access to sufficient quantities of locally available items for an active and healthy life. It also provides indicators on the cost and affordability of an energy-sufficient diet and of a nutrient-adequate diet. These indicators are explained in detail in the Food Prices for Nutrition DataHub.

Version 3.0, estimated in July 2024, uses the 2021 global food retail price data from the International Comparison Program (ICP) and updates the methodology of calculating the affordability indicators, including indicators measuring the ratio between diet costs and international food poverty lines and indicators measuring the share and volume of the population unable to afford each diet, and they are based on the latest Poverty and Inequality Platform (PIP) data expressed in 2017 purchasing power parity dollars (PPP).

Estimates for the prevalence and number of people unable to afford a healthy diet were imputed for countries with missing information based on their regional and global aggregates. Countries' income classifications at the aggregate reporting level follow the calendar year of 2022 standard (the fiscal year of 2024 of the World Bank).
