First press release of revised Index of Core Industries (ICI) series with base year 2022-23
DPIIT revises the Index of Core Industries to the 2022-23 base year, adds iron ore, and releases June 2026 provisional data
- The Index of Core Industries is compiled monthly and is used to track production trends in major industrial sectors.
- The revised Index of Core Industries series replaces the older series with a new base year and a revised industrial basket.
- June 2026 provisional data show stronger growth in core industries, led mainly by iron ore and electricity.
The Office of Economic Adviser, Department for Promotion of Industry and Internal Trade, has released the revised Index of Core Industries (ICI) series with base year 2022-23. The revised series replaces the older 2011-12 series and begins with provisional data for June 2026.
The revision matters because the Index of Core Industries is a key high-frequency indicator of industrial activity. It is closely watched for reading trends in production, infrastructure-linked demand, and the broader industrial cycle.
What changed in the revised Index of Core Industries series
UPSC can ask about the composition, base year revision, linkage with the Index of Industrial Production, and the role of core industries in reading industrial trends. The revision also tests whether a candidate can distinguish a statistical rebasing exercise from a policy intervention.
