Prevalence of unaffordability of a nutrient adequate diet
The indicator estimates the percentage of individuals in a population whose disposable income, net of the amount needed to acquire basic non-food goods and services, is lower than the average cost of the least-expensive nutrient adequate diet in a country. The expenditures for basic non-food needs are calculated as average non-food expenditure shares of low-income consumers multiplied by international poverty lines set by the World Bank. The non-food expenditure share is 37% and 44% in low-income and lower-middle-income countries for the second quintile of consumers, and 54% in upper-middle-and-high-income countries for the first quintile of consumers, according to household surveys compiled by the World Bank. The international poverty lines are $2.15/day for low-income countries, $3.65/day for lower-middle-income countries, $6.85/day for upper-middle-income countries, and $24.36/day for high-income countries, in 2017PPP$. Countries' income classifications follow the calendar year of 2021 (fiscal year of 2023 of the World Bank) as the base year of the latest ICP cycle.
