The Ministry of Statistics and Programme Implementation (MoSPI) has launched a fresh series of the IIP. The overhaul aligns the index with the current industrial structure and introduces new sectors, a revised basket of goods, and finer granularity.
Key Developments
- Base year shifted from 2011‑12 to 2022‑23, the first revision in over a decade.
- New sector added: Gas Supply and Water Supply, Sewerage & Waste Management, expanding coverage beyond the traditional Mining, Manufacturing and Electricity.
- Weights now derived from GVA data in the National Accounts Statistics (base 2022‑23) and the Annual Survey of Industries.
- Item basket enlarged to 1,042 products across 463 groups. Additions include CCTV cameras, stents, vaccines and magnetic‑stripe cards; deletions remove kerosene, fluorescent tubes, CFLs and tyre tubes.
- Granular sub‑indices introduced for renewable vs non‑renewable electricity and three mining sub‑categories (fuel, metallic including rare‑earth, and non‑metallic minerals).
- Parallel overhaul of the CPI with a new base year 2024, a larger basket of 358 items and inclusion of rural house rent.
Important Facts
• April 2026 industrial output rose 4.9%, outpacing March's 3.2% growth.
• Sector‑wise weight changes: Mining & Quarrying falls from 14.37% to 11.05%; Electricity & Gas Supply rises from 7.99% to 10.87%; the new Water Supply sector accounts for 2.02%.
UPSC Relevance
The revised IIP is a frequent UPSC fact‑check for questions on industrial growth, sectoral composition and methodology of economic indicators. Understanding the shift in base year helps candidates compare historic trends accurately. The expanded coverage mirrors India's move towards service‑oriented and environmental sectors, a theme in GS3 questions on structural transformation. The new CPI base year 2024 and the inclusion of rural house rent are vital for inflation‑targeting questions, especially regarding the RBI’s mandate (GS3: Economy).
Way Forward
Students should memorise the new base year (2022‑23), the added sector (Gas Supply & Water Supply, Sewerage & Waste Management), and the key weight shifts. Practice comparing pre‑ and post‑revision IIP numbers to gauge the impact of methodological changes. Keep an eye on how the RBI cites the revised CPI in its monetary‑policy statements, as this will often appear in current‑affairs questions.
