Index of Eight Core Industries, Significance, Index of Industrial Production (IIP)

The Index of Eight Core Industries (ICI) measures the production performance of eight key sectors that drive India’s industrial growth, including Coal, Steel, Electricity, and Refinery Products. These core industries are significant as they contribute 40.27% to the IIP and influence overall economic activity and other industries.

The Index of Industrial Production (IIP) complements the ICI by tracking short-term changes in the volume of production across manufacturing, mining, and electricity sectors. Together, the ICI and IIP provide a clear picture of industrial trends and economic health in India. The Index of Industrial Production (IIP) in India is compiled and published monthly by the National Statistical Office (NSO), under the Ministry of Statistics and Programme Implementation (MoSPI).

The Eight Core Industries

The eight core industries are considered drivers of industrial growth due to their large contribution to economic activity. These industries collectively account for 40.27% of the weight of items in the Index of Industrial Production (IIP).

1. Refinery Products
2. Electricity
3. Steel
4. Coal
5. Crude Oil
6. Natural Gas
7. Cement
8. Fertilizers

Index of Eight Core Industries

The weightage of the eight core industries in the ICI indicates their relative contribution to overall industrial production, with Refinery Products having the highest weightage (28.04%) and Fertilisers the lowest (2.63%). These weights help assess the impact of each sector on the economy.
