The nutritious price index and food security of urban and rural households in Iran
High food inflation rate in Iran in recent years places many low-income households at risk of malnutrition. Since food security and nutrition are essential dimensions of the Sustainable Development Goals (SDGs), this paper aims to create a reliable measure of food security in Iran among different income decile groups and urban and rural areas. The paper also attempts for the first time, to extract health-related indicators from the consumer price index (CPI) and the Household Income and Expenditure (HIES) surveys historically conducted by the Statistical Center of Iran (SCI). This study reaggregates CPI price data to calculate the nutritious food price index (NPI) for urban and rural households in Iran. Moreover, the “Cost of a Recommended Diet (CoRD)” method is used to measure the trends and spatial variations in the costs of nutrition. The paper presents the results of using the CoRD method for regional levels and decile income groups. Results show that the cost of a healthy diet increased in recent years. Likewise, the healthy food price index is higher than the overall food price index. Finally, the results indicate that the NPIs in urban areas are higher than in rural areas.
