For Prelims

Core industries:

  • Core Industries of an economy are the main or the key industries which determine the strength of an economy.
  • They make up for about 27% of the weight of items included in the Index of Industrial Production (IIP).
  • The eight core sector industries in decreasing order of their weightage are:
  • Refinery Products> Electricity> Steel> Coal> Crude Oil> Natural Gas> Cement> Fertilizers.

Index of Industrial Production (IIP)

  • The Index of Industrial Production (IIP) is calculated by evaluating the short-term changes in the volume of production of a basket of industrial products during a given period of time with respect to that during a chosen base period.
  • India’s first official attempt to compute the Index of Industrial Production (IIP) was done way before the first recommendation on the subject came at the international level.
  • Central Statistical Organization, currently known as National Statistics Office (NSO), has been compiling and publishing IIP since the inception of the in 1951.
  • IIP has been broadly classified into 3 sectors, viz, Mining, manufacturing, and electricity.
  • It can also be divided based on usage into 3 viz, Basic Goods, Capital Goods, and Intermediate Goods.

Index of Eight Core Industries (ICI)

  • The ICI is prepared and released by the Office of the Economic Adviser (OEA), Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce & Industry.
  • ICI is a measure of the individual and collective performances of production in the eight core industries.
