The growth of eight key infrastructure sectors i.e. the Index of Eight Core Industries (ICI) slowed down to 4.3 per cent in May 2023 mainly because of a decline in the production of crude oil, natural gas, and electricity. The core sector growth was 19.3 per cent in May 2022 while in April 2023 the key infra sectors recorded a growth rate of 4.3 per cent. During April-May this fiscal year, the output growth of these eight sectors slowed down to 4.3 per cent as against 14.3 per cent in the year-ago period. 


According to the release by the government, ICI measures combined and individual performance of production of eight core industries viz. Coal, Crude Oil, Natural Gas, Refinery Products, Fertilizers, Steel, Cement and Electricity. The eight core sectors comprise 40.27 per cent of the weight of items included in the Index of Industrial Production (IIP).
