  • This is the 10th revision of the All-India IIP; the first IIP was compiled with 1937 as the base year.
  • The revision was carried out under the Technical Advisory Committee for IIP (TAC-IIP).
  • New sectors such as Gas Supply, Water Supply, Sewerage, and Waste Management have been added to improve coverage.
  • The product basket has been expanded from 839 items to 1,042 products (463 item groups).
  • Mining classification has been expanded to cover Fuel Minerals, Metallic Minerals (including Rare Earth Minerals), and Non-Metallic Minerals (including Minor Minerals), providing more detailed industrial data.
  • The Electricity Index now separately tracks electricity generation from renewable sources (solar, wind, hydro, etc.) and non-renewable sources (coal, gas, nuclear, etc.), providing a clearer picture of India's energy production mix.
