The new book published by the Center for Development Research and Foresight, "Investigation of the Income Distribution Trend of Urban, Rural, and National Households in the Last Two Decades," is tackling the ever-present issue of income inequality in Iran.

Authored by Ali Akbar Khosravi Nejad and Muslim Abiri, the book emphasizes the significance of understanding income distribution patterns for policymakers to address the needs of vulnerable populations. By analyzing these trends, researchers and governing bodies can gain valuable insights to develop effective policies and interventions.

This book offers a detailed analysis of income inequality in Iran over the past two decades. It utilizes various established methods to measure inequality, including:

• Ratios and shares:This approach compares the income levels of different groups within the population.
• Gini coefficient:A common metric for income inequality, where 0 signifies perfect equality and 1 represents absolute inequality.
• Generalized entropy index:This measure captures the overall level of inequality and the distribution of income across various groups.
• Atkinson index:This index goes beyond the level of inequality, considering society's aversion to it as well.

The book's analysis extends beyond income to delve into consumption expenditure trends. It examines how spending patterns on essential categories like food, housing, healthcare, and transportation have evolved over the past two decades across different segments of the Iranian population.

This comprehensive exploration of income and consumption expenditure trends provides valuable insights for researchers, policymakers, and anyone interested in understanding the complexities of income inequality and its impact on different segments of Iranian society.
