Q. Distinguish between the Human Development Index (HDI) and the Inequality-adjusted Human Development Index (IHDI) with special reference to India. Why is the IHDI considered a better indicator of inclusive growth?

Model Answer:

Published by the UNDP, HDI measures average achievements in health, education, and income, whereas IHDI discounts these averages to account for inequality.

1. Distinguishing HDI and IHDI (Indian Context)

• Measurement Approach: HDI calculates average national achievements, while IHDI applies Atkinson’s inequality measure to penalize disparities.
• Development Perspective: HDI reflects “potential” human development; IHDI reflects the “actual” development experienced by citizens.
• India’s Reality Check: In the UNDP HDR 2023-24, India’s HDI is 0.644, but its IHDI sharply falls to 0.444.
• Inequality Penalty: This 0.200 drop signifies a severe ~31.1% loss in India’s overall human development due to structural inequalities.

2. Why IHDI Better Captures Inclusive Growth

• Unmasks Skewed Averages: Prevents outlier wealth from masking mass deprivation (Oxfam: Top 1% hold 40% of India’s wealth).
• Highlights Distributional Inequity: Accurately tracks unequal grassroots access to essential healthcare and quality education (urban-rural divides).
• Real Capability Assessment: Reflects the true standard of living experienced by the bottom pyramid, moving beyond per-capita illusions.
• Drives Equitable Policy: Shifts governmental focus from aggregate GDP growth to targeted redistribution mechanisms (DBT, MGNREGA).

Integrating IHDI into macroeconomic policymaking is essential for India to transition from mere aggregate growth to authentic “Sabka Saath, Sabka Vikas”, directly advancing SDG 10 (Reduced Inequalities).
