What you should know about this indicator

  • A healthy diet meets nutritional standards set by dietary guidelines, with sufficient diversity and quantity within and between food groups to achieve nutrient adequacy and protect against diet-related diseases.
  • This indicator is calculated as the percentage of a country's population that is unable to afford a healthy diet, multiplied by the country's population.
  • Population counts all residents regardless of legal status or citizenship.
  • 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 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).

Population data are sourced from the United Nations Department of Economic and Social Affairs (UN DESA) 2022 revision of the World Population Prospects and World Development Indicators (WDI) of the World Bank. The WDI source data from:
