What you should know about this indicator

  • This percentage accounts for a portion of income that can be credibly reserved for food, based on observations that the population in low-income countries spend, on average, 52% of their income on food, as derived from the 2017 national accounts household expenditure data of the World Bank's International Comparison Programme (ICP).
  • Income data are provided by the World Bank's Poverty and Inequality Platform. A value of zero indicates a null or a small number rounded down at the current precision level.

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 2.1 differs from Version 2.0 in that 2.1 reflects the latest income data from the World Bank's Poverty and Inequality Platform (PIP) that were updated in the fall of 2023, for the following diet affordability indicators: the share and volume of the population that cannot afford the diet, based on national income distributions expressed in 2017 PPP dollars. Furthermore, Version 2.1 updates and reports population data provided by World Development Indicators.
