What Is the Index of Core Industries (ICI)?

The Index of Core Industries (ICI) calculates changes in production levels in industries critical to the economic and industrial development. The given September 2026 report considers 2022-23 as the base year.

The index is computed and released by the Office of the Economic Adviser (OEA), Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry.

According to the given dataset, the following nine industry groups are used: coal, natural gas, crude oil, refinery products, fertilizers, steel, cement, electricity, and iron ore.

As it can be seen from the above-listed industries, iron ore is listed separately, and therefore it should be considered according to the sector classifications and weights provided by this particular report.

Weight of the Each Industry in the September 2026 Numbers

The total is nearly 100% due to the rounding in the published weights.

The highest weight in this particular dataset belongs to electricity, then refinery products, and steel. Thus, the fluctuations in these sectors can affect the index significantly.
