GDP Base Year Revision (2011-12 to 2022-23)
The base year of India's GDP series is the reference year against which all other years' output is valued at constant prices to compute "real" GDP growth. India's National Statistical Office (NSO), under the Ministry of Statistics and Programme Implementation (MoSPI), released a new GDP series with base year 2022-23 (replacing the base year 2011-12) on 27 February 2026.
- Base years are periodically revised to incorporate more recent consumption patterns, new data sources (e.g., GST returns, MCA-21 corporate filings), and updated sectoral weights that better reflect the current economy's structure.
- FY 2022-23 was chosen as it is considered a "normal" post-COVID year with comprehensive, robust underlying data across sectors.
- Under the new series, real GDP growth for 2025-26 was estimated at 7.6%, compared to 7.1% for 2024-25 under comparable new-series terms.
- Previous base year revisions in India: 2004-05 to 2011-12 (in force from January 2015), reflecting how periodically (roughly every 7-10 years) the exercise is repeated.
