Core Sector in India - Core Sectors and their weightage in Index of Industrial Production(IIP)

What are the core sectors of India?

The Core Sector of India includes Coal, Crude Oil, Natural Gas, Refinery Products, Fertilizers, Steel, Cement, and Electricity. It comprises 40.27 percent of the weight of items included in the Index of Industrial Production (IIP). The Core sectors of an economy are the primary or important industries.

The Office of the Economic Adviser (OEA), Department of Industrial Policy and Promotion (DIPP), and Ministry of Commerce and Industry compile and publish the index.

The Index of Key Industries evaluates the performance of the eight core industries of coal, crude oil, natural gas, refinery products, fertilisers, steel, cement, and power in aggregate and individual production terms. These industries serve as the foundation for all other industries. The current year’s production of these industries is computed using the 2011-2012 base year.

• Core industries include eight sectors of the Indian economy that are mentioned below:

Sector	Description	Weightage
Coal	Coal production, excluding Coking coal.	10.33 %
Electricity	generation of thermal, nuclear, hydro	19.85 %
Crude Oil	Total crude oil production.	8.98 %
