The Index of Industrial Production (IIP) is a monthly indicator of changes in the volume of industrial output. It uses 2022-23 = 100 as its base year.

What the Index Shows

  • Industrial output: It tracks whether production has increased or decreased compared with the same month of the previous year.

  • Early signal: It gives an early view of industrial activity before full quarterly Gross Domestic Product estimates are released.

Major Sectors

  • Manufacturing: It covers factory production and is the largest part of the index.

  • Mining and quarrying: It covers extraction of minerals and fuels.

  • Electricity and gas supply: It covers power generation and gas supply.

  • Water supply and waste management: It covers water services, sewerage, and waste management.

Why It Matters

  • Policy signal: The Reserve Bank of India and the government use IIP trends to assess industrial conditions.

  • GDP input: The National Statistical Office uses IIP as an input for quarterly GDP estimates.
