Q. Examine the rationale behind expanding the Index of Core Industries from eight to nine industries. What does the inclusion of Iron Ore indicate about India's industrial structure? (15 marks, 250-350 words)

The Index of Core Industries (ICI), compiled monthly by the Office of Economic Adviser, DPIIT, is India's key high-frequency barometer of basic and infrastructure industries. Its revised series with base year 2022–23, released on 20 July 2026, expands the basket from eight industries to nine by adding Iron Ore [1] — a change driven by both statistical necessity and structural shifts in the economy.

Rationale for the expansion - Rebasing for representativeness: the 2011–12 base no longer mirrored current production patterns; the new base aligns ICI with the rebased IIP series (2022–23), from which ICI weights are derived and redistributed pro-rata [1][2]. - Criterion of intensive use: Iron Ore qualifies as "core" because of its intensive use across the production chain and its contribution to industrial development [1]. - Methodological cleanup: only raw coal is now counted, dropping coal middlings and washed coal to avoid duplication, while steel shifts from net to gross production data — improving accuracy [1]. - Comparability: a back series from April 2023 ensures continuity for trend analysis and policy use [1].

What Iron Ore's inclusion signals - Deepening of the metals value chain: iron ore's entry reflects India's growing domestic ore-to-steel integration rather than reliance on imports or exports of raw ore. - Capital-goods and construction-led growth: mining now visibly anchors an infrastructure-heavy growth cycle; iron ore recorded the highest growth among core sectors in June 2026 [1]. - Widening beyond energy: the earlier basket was energy-dominated — coal, crude oil, natural gas, refinery products, electricity — with all eight comprising 40.27% of IIP weight [3]; adding a mineral input broadens the index's coverage of upstream industry.

The expansion is therefore less a technical footnote than a mirror of India's shift toward a mining-and-manufacturing-intensive growth path. Sustaining it will require aligning ore availability with the National Mineral Policy and sustainable mining norms, so that statistical modernisation is matched by a resource base capable of supporting long-term industrial self-reliance.
