New GDP Series

Context

• The government released a new GDP series (base year 2022–23) in February 2026 to provide a more accurate and updated picture of the economy, replacing the older 2011–12 base year.
• This revision reflects structural changes in the economy and improves data quality and methodology.

Changes Made in GDP Calculation

• Updated base year and revised estimates
  • GDP estimates for 2023-24 is ₹289.84 lakh crore while for 2024-25 is ₹318.07 lakh crore.
  • These are 3–4% lower than earlier estimates, indicating better realism.
• Improved sectoral representation
  • Share in GVA (2024–25):
    • Primary: 21.4%
    • Secondary: 25.8%
    • Tertiary: 52.9%
• Methodological refinements
  • Better classification of companies: Multi-activity firms’ GVA is now distributed across activities.
  • Expanded corporate coverage: Inclusion of Limited Liability Partnerships (LLPs) and non-reporting firms using MCA data.
  • Improved household sector estimation: Use of ASUSE (GVA per worker) and PLFS (employment data).
  • Use of double deflation & volume methods: Aligns estimates with global standards.
  • Consumption estimation improved: Based on Household Consumption Expenditure Survey (2022–23).

Advantages of These Changes

• Greater accuracy and realism: Updated base year reflects current economic structure and trends more accurately.
• Improved data coverage: Inclusion of LLPs and better corporate data ensures comprehensive estimation.
• Better sectoral insights: More precise allocation of output improves understanding of sectoral contributions.
• Alignment with global practices: Adoption of advanced methods enhances international comparability and credibility.
• Improved policy relevance: Reliable data helps policymakers take informed economic decisions.

Issues Regarding the Changes

• State-level data limitations
  • Difficulty in allocating corporate GVA across States due to lack of disaggregated data.
  • Reliance on ASI data, which has a limited coverage, may distort State GDP estimates.
• Data gaps in corporate sector: 
  • Not all firms file returns, leading to estimation challenges despite adjustments.
• Volatility in household sector estimates
  • GVA estimates based on ASUSE show year-to-year fluctuations, affecting reliability.
• Sampling and methodological concerns
  • Current survey methods may not fully capture dynamic changes across sectors and regions.

Way Forward

• Strengthen data systems: Integrate MCA, GST, and ASI databases to improve accuracy of State-level estimates.
• Improve survey design: Introduce rotating panel surveys (like PLFS) for better consistency in ASUSE data.
• Enhance coverage of enterprises: Ensure more firms report data to reduce reliance on estimation techniques.
• Refine methodology continuously: Regular updates in methods to reflect changing economic realities.
• Focus on transparency: Clear communication of methodology to build trust in official statistics.

Conclusion

• The new GDP series is a significant step towards better measurement of India’s economy. However, improving data quality and institutional capacity will be key to ensuring that these estimates remain reliable and useful for policymaking.
