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?
Approach · directive: “distinguish / why”
What it asks · Set the HDI against the IHDI in concept and measurement, read India’s numbers through both, and argue why the IHDI better shows whether growth is shared.
It asks 2 things — answer each
- Distinguish between the HDI and the IHDI in concept and measurement, with special reference to India's numbers
- Explain why the IHDI is considered a better indicator of inclusive growth
Open with · India's HDI is 0.685 (2023, rank 130 of 193), yet inequality cuts it by 30.7% (HDR 2025); that gap is the case for the IHDI.
Cover
- HDI: geometric mean of life expectancy, schooling (mean and expected years) and GNI per capita — an average that is blind to distribution.
- IHDI: each dimension is discounted for inequality; it equals the HDI only under perfect equality — the percentage gap is the inequality loss.
- India (HDR 2025): HDI 0.685, rank 130 of 193; inequality lowers the value by about 30.7%, among the higher losses in the region.
- Sources of India’s loss: income and wealth concentration, gender gaps (low female labour-force participation), unequal learning outcomes, regional gaps in health.
- Why IHDI suits inclusive growth: it shows who shares the gains — a rising HDI with a widening loss signals growth that leaves many behind.
- Policy use: points to targeting — school quality, primary health, jobs for women, lagging States and districts (Aspirational Districts approach).
- Limits: it does not capture group inequality (caste, gender) directly, depends on survey data, and ignores freedoms; read it with the MPI, GDI and GII.
Close with · Tracking the inequality loss beside the headline HDI is how India measures progress on SDG 10, 'reduce inequality within and among countries', and makes growth shared, not merely averaged.

Model answer· 215words · Minimalist IAS
India's HDI is 0.685 (2023, rank 130 of 193), yet inequality cuts it by 30.7% (HDR 2025, per a Deccan Herald report). That gap is the whole case for the IHDI.
How the HDI and the IHDI differ
- HDI: a geometric mean of life expectancy, schooling and GNI per capita, blind to distribution.
- IHDI: each dimension is discounted by its Atkinson inequality measure; it equals the HDI only under perfect equality.
- Loss: the percentage gap between them is the 'loss due to inequality'.
| Aspect | HDI | IHDI |
|---|---|---|
| Asks | Average achievement | Achievement after distribution |
| India, HDR 2025 | 0.685, rank 130 | about 30.7% lower (press report) |
Why the IHDI better indicates inclusive growth
- Shows who gains: a rising HDI with a widening loss means growth that leaves many behind.
- Locates exclusion: India's loss stems from concentrated income, low female labour-force participation and uneven learning and health, pointing policy to school quality, primary health and women's jobs.
- Targets regions: dimension-wise losses support district focus, as in the Aspirational Districts approach.
- Limits: it misses caste and gender group gaps and rests on surveys; read it with the MPI, GDI and GII.
Tracking the inequality loss beside the headline HDI is how India measures progress on SDG 10, 'reduce inequality within and among countries', and makes growth shared, not merely averaged.
