Distinguish between the Human Development Index (HDI) and Inequality-adjusted Human Development Index (IHDI) with special reference to India. Why is the IHDI considered a better indicator of inclusive growth?
Introduction
The Human Development Index (HDI), introduced by the United Nations Development Programme (UNDP), measures a country's average achievements in health, education, and standard of living. However, it does not account for inequalities within a population. To address this limitation, the Inequality-adjusted Human Development Index (IHDI) was developed, which adjusts the HDI for inequality in the distribution of each dimension. For a diverse and unequal country like India, the IHDI provides a more nuanced understanding of development.
Key Differences Between HDI and IHDI
| Parameter | HDI | IHDI |
|---|---|---|
| Definition | Measures average achievements in health, education, and income. | Adjusts HDI to reflect inequality in the distribution of these dimensions. |
| Focus | Focuses on aggregate national performance. | Focuses on equitable distribution of development outcomes. |
| Inequality Adjustment | Does not account for inequality. | Penalizes HDI score based on the level of inequality. |
| Value Range | Always higher or equal to IHDI. | Always lower or equal to HDI. |
| Relevance to Policy | Provides a broad overview of development. | Highlights disparities, aiding in targeted policy interventions. |
Why IHDI is a Better Indicator of Inclusive Growth
1. Accounts for Inequality
- HDI assumes equal distribution of resources, which is unrealistic in countries like India with significant disparities.
- IHDI penalizes inequality, making it a more accurate measure of inclusive growth.
2. Reflects Real Development Outcomes
- HDI may overestimate development by ignoring disparities. For instance, India’s HDI in 2021 was 0.633, but its IHDI was significantly lower at 0.475 (UNDP Report 2021). This gap highlights the impact of inequality.
3. Focus on Marginalized Groups
- IHDI emphasizes the need to uplift vulnerable sections such as women, Scheduled Castes, Scheduled Tribes, and rural populations, aligning with SDG Goal 10 (Reduced Inequalities).
4. Policy Implications
- IHDI provides actionable insights for targeted interventions in health, education, and income distribution, ensuring equity-driven growth.
India’s Performance: HDI vs. IHDI
- HDI Rank (2021): 132 out of 191 countries.
- IHDI Rank: Lower due to stark inequalities in income distribution, gender parity, and access to education.
- Regional Disparities: States like Kerala perform well on both indices, while states like Bihar show a significant gap between HDI and IHDI.
Way Forward
- Reducing Inequalities: Focus on inclusive policies such as targeted welfare schemes (e.g., PM Jan Dhan Yojana, Ayushman Bharat).
- Improving Social Indicators: Strengthen education and healthcare systems, especially in rural and marginalized areas.
- Gender Equality: Promote women’s participation in the workforce and address gender-based disparities.
- Data-Driven Policies: Use IHDI insights to design state-specific interventions for equitable growth.
Conclusion
While the HDI provides a broad measure of development, the IHDI is a more comprehensive and realistic indicator, especially for a diverse and unequal country like India. By highlighting disparities, the IHDI aligns with the principles of inclusive growth and helps policymakers focus on reducing inequalities, ensuring that no one is left behind.
