The combined Index of Eight Core Industries (ICI) increased by 12.1per cent (provisional) in August 2023 as compared to the Index of August 2022. The production of all Eight Core Industries (namely, Cement, Coal, Crude Oil, Electricity, Fertilizers, Natural Gas, Refinery Products and Steel) recorded positive growth in August 2023 over the corresponding month of last year. Details of annual and monthly indices and growth rates are provided at Annex I & II respectively.
- The ICI measures combined and individual performance of production of eight core industries viz. Cement, Coal, Crude Oil, Electricity, Fertilizers, Natural Gas, Refinery Products and Steel. The Eight Core Industries comprise 40.27 percent of the weight of items included in the Index of Industrial Production (IIP).
- The final growth rate of Index of Eight Core Industries for May 2023 is revised to 5.2 per cent. The cumulative growth rate of ICI during April to August, 2023-24 is 7.7 per cent (provisional) as compared to the corresponding period of last year.
4.The summary of the Index of Eight Core Industries is given below:

Note 1: Data for June 2023, July, 2023 and August, 2023 are provisional. Index numbers of Core Industries are revised/finalized as per updated data from source agencies.
Note 2: Since April 2014, Electricity generation data from Renewable sources are also included.
Note 3: The industry-wise weights indicated above are individual industry weights derived from IIP and blown up on pro rata basis to a combined weight of ICI equal to 100.
Note 4: Since March 2019, a new steel product called Hot Rolled Pickled and Oiled (HRPO) under the item ‘Cold Rolled (CR) coils’ within the production of finished steel has also been included.
Note 5: Release of the index for September, 2023 will be on Tuesday 31st October, 2023.
