In January 2015 the Central Statistics Office revised India's national-accounts series, changing both the methodology and the headline measure of GDP to align with international (System of National Accounts 2008) standards.
Key changes after 2015
- Base year: shifted from 2004-05 to 2011-12, updating relative prices and the production structure.
- Headline measure: the reference shifted from GDP at factor cost to GDP at market prices, with Gross Value Added (GVA) at basic prices used for sectoral analysis. GVA plus product taxes minus product subsidies equals GDP.
- Data source: a move to the enterprise-level MCA-21 corporate database, replacing older sample-based data and better capturing the organised private corporate sector.
Implications
- Estimates became more comprehensive and internationally comparable.
- The new series showed somewhat higher growth than the old one, sparking debate over data quality and comparability across the two series.
Overall, the revision modernised India's growth measurement, though it required care in comparing pre- and post-2015 figures.
What an examiner expects to see
- 2015 revision by CSO aligned accounts with SNA 2008 standards
- Base year changed from 2004-05 to 2011-12
- Headline shifted from GDP at factor cost to GDP at market prices
- GVA at basic prices used for sectoral analysis: GVA + product taxes - product subsidies = GDP
- Adoption of enterprise-level MCA-21 corporate database over older sample data
- Better coverage of the organised corporate sector and greater comparability
- New series showed higher growth, prompting debate on methodology and comparability
Concrete cases, schemes and judgments
- Base-year revision from 2004-05 to 2011-12 (effective January 2015)
- MCA-21 database of the Ministry of Corporate Affairs as the new corporate data source
- System of National Accounts 2008 as the international benchmark
- GVA-based sectoral estimation replacing GDP-at-factor-cost presentation
