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.
The question has 2 parts — 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 · UNDP’s HDI averages a country’s achievement in health, education and income; the IHDI discounts each of these for how unequally it is distributed — the gap is the ‘loss’ due to inequality.
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 · Growth becomes development only when it is widely shared; tracking the IHDI alongside the HDI keeps India’s policy focused on narrowing the inequality loss.

- UNDP's technical notes: the IHDI draws on the Atkinson family of inequality measures and is a geometric mean of the three dimension indices after each is discounted for its inequality. UNDP, Human Development Report 2025 — Technical notes (Technical note 2: Inequality-adjusted Human Development Index) ↗“which draws on the Atkinson (1970) family of inequality measures. It is computed as a geometric mean of inequality-adjusted dimensional indices.”

UNDP's HDI averages a country's achievement in health, education and income; the Inequality-adjusted HDI discounts each of these for how unequally it is shared, and the gap between the two is the 'loss' due to inequality.
HDI versus IHDI
- Measure: the HDI is a geometric mean of life expectancy, schooling and GNI per capita — an average blind to distribution. The IHDI discounts each dimension by its inequality (Atkinson measure) and equals the HDI only under perfect equality.
- India (HDR 2025): HDI 0.685, rank 130 of 193; inequality lowers it by about 30.7%, among the higher losses in the region.
- Where India loses: concentrated income and wealth, gender gaps such as low female labour-force participation, uneven learning outcomes and regional gaps in health.
Why the IHDI better tracks inclusive growth
- It shows who shares the gains: a rising HDI with a widening loss signals growth that leaves many behind.
- It locates the dimension where exclusion is worst, so policy can target school quality, primary health, jobs for women and lagging districts.
- Limits: it misses group inequality by caste or gender and rests on survey data; read it with the MPI, GDI and GII.
Growth becomes development only when widely shared; tracking the IHDI beside the HDI keeps policy focused on shrinking India's inequality loss, not only raising the average.
