Revisiting India’s Industrial Barometer: Base Year Revision of IIP, Pg16.

Key Highlights:

• The Ministry of Statistics and Programme Implementation (MoSPI) is finalising a new IIP base year (likely 2022–23) to replace the current 2011–12 base.
• The revision aims to align with the new National Accounts (GDP) base year and global statistical standards.
• The Technical Advisory Committee on Statistics of Prices and Cost of Living (TAC-ISPCL) has already endorsed the proposal.
• The revised IIP basket will include new products and sectors reflecting digitalisation, clean energy, and post-pandemic manufacturing trends.
• Over 925 items will be covered, ensuring a higher representation of industries under Make in India and Atmanirbhar Bharat initiatives.

Detailed Insights:

• Why Base Year Revision Matters:
  • Economic structure evolves — new sectors like semiconductors, EV components, and solar modules gain prominence while older ones decline.
  • Updating the base year ensures accurate tracking of current industrial output, inflation, and policy planning.
• Expansion of Scope:
  • The new IIP basket will better capture emerging industries and products such as LED lighting, mobile components, electric vehicles, and green technology.
  • Inclusion of services-linked manufacturing and MSME-driven outputs for a comprehensive picture.
• Improvement in Methodology:
  • Use of GST and e-invoicing data to improve real-time accuracy.
  • Enhanced treatment of “not elsewhere classified” items to avoid data loss.
  • Revised seasonal adjustment factors to capture genuine production cycles and remove statistical distortions.
• Policy Impact:
  • A modernised IIP will help policymakers track industrial recovery, employment, and productivity.
  • It supports evidence-based decisions for schemes like PLI (Production Linked Incentive) and National Industrial Corridor Development.

Scientific/Technical Concepts Involved:

• Index of Industrial Production (IIP): A monthly indicator that measures the volume of production in mining, manufacturing, and electricity.
• Base Year: The benchmark year for comparison of economic activity to adjust for inflation and structural changes.
• Seasonal Adjustment: A statistical technique to remove fluctuations caused by seasonal patterns in production.
• Data Substitution Technique: Replacing discontinued products in the IIP basket with new substitutes to maintain data continuity.
