India's Economic Growth and Revisions

Indian Economic Growth Overview

1. GDP Growth Data:

   • Q3 2025 GDP growth (October-December): 7.8% (new series with 2022-23 as the base year).
   • Estimated GDP growth for 2025-26: 7.6% (revised from the earlier estimate of 7.4%).
   • Revisions under the old series (base year 2011-12):
     • Q1 2025: 6.7% (previously 7.8%).
     • Q2 2025: 8.4% (previously 8.2%).

     • FY 2024-25: 7.1% (previously 6.5%).

2. Methodological Changes and New Series:

   • New series methodology uses double-deflation instead of the single-deflator method to calculate real GDP, enabling more accurate measurements.
   • Incorporates new data sources such as:
     • GST (Goods and Services Tax)
     • e-Vahan
     • Annual Survey of Unincorporated Sector Enterprises
     • Periodic Labour Force Survey
   • Integration of national accounts data with Supply and Use Tables to address discrepancies in GDP calculations.

3. Timeline for Complete Data:

   • MoSPI expects to release the complete back series of GDP data (prior to 2022-23) by December 2026.

4. Significance of Revisions:

   • The revisions raise questions regarding previous assessments of economic growth, particularly contentious figures from the 2013-14 fiscal year.
   • The new system aims to align more closely with international best practices, enhancing the reliability of economic data.

5. Historical Context:

   • The last significant revision of GDP series by the Ministry of Statistics and Programme Implementation (MoSPI) occurred in 2015 with the base year changing from 2004-05 to 2011-12.

Key Considerations for Students:

• Understand the implications of adopting new methodologies in economic measurement.
• Review how different base years can affect growth calculations and projections.
• Consider the importance of accurate GDP estimations for economic policy and planning.
• Familiarize with the role of various data sources in producing economic statistics.

Conclusion: The adoption of a new GDP calculation methodology marks a significant shift in India's economic measurement approach, aimed at enhancing accuracy and credibility against past inaccuracies. The anticipated release of the back series data is crucial for historical economic analyses and understanding growth trends.
