India’s ICI gets an updated series: what has changed?
Union Government has updated the Index of Core Industries to a 2022-23 base year, added iron ore, and revised sector weights and methods to align core industry measurement with newer national statistical series.
- The Index of Core Industries is a monthly measure of key industrial sectors and is often read alongside the Index of Industrial Production.
- Base-year revisions are used to keep statistical series aligned with current production structures and sector weights.
- The updated series changes steel measurement to a gross output basis and limits coal measurement to raw coal to reduce double counting.
The Union Government has updated the Index of Core Industries (ICI) series. The revision matters because the ICI is a key monthly indicator of industrial activity and is used alongside other official statistics to judge the state of the economy.
The updated series brings the ICI closer to recently revised national statistical series, including Gross Domestic Product (GDP), Gross Value Added (GVA), inflation measures, and the Index of Industrial Production (IIP). The revision reflects a broader effort to keep India’s statistical base aligned with current production patterns.
What changed in the Index of Core Industries
Questions can test the composition, base year, and methodology of the Index of Core Industries, and can also ask whether statistical revision changes the interpretation of industrial growth. The topic also fits broader Mains themes on the quality of economic data and the relationship between sectoral indices and policy analysis.
