Q. Explain the difference between computing methodology of India’s Gross Domestic Product (GDP) before the year 2015 and after the year 2015.

Model Answer: 

In 2015, the Central Statistics Office (CSO) revised India’s GDP computation methodology to comprehensively align with the UN System of National Accounts (SNA) 2008.

Pre-2015 GDP Computing Methodology

• Base Year: Calculated using 2004-05 as the standard base year.
• Headline Metric: GDP was primarily measured and reported at ‘Factor Cost’ (actual production costs).
• Data Sources: Relied heavily on the Annual Survey of Industries (ASI) and RBI sample studies.
• Establishment Approach: Valued manufacturing solely at the plant/factory level, often missing ancillary corporate value addition.

Post-2015 GDP Computing Methodology

• Base Year Shift: Updated to 2011-12 to capture contemporary economic realities and newer industries.
• Market Price Metric: Headline GDP is now measured at ‘Market Prices’ (GVA at basic prices + indirect taxes – subsidies).
• Enterprise Approach: Adopted the comprehensive MCA-21 corporate database, capturing value addition at the holistic enterprise/head-office level.
• Broadened Financial Coverage: Included diverse financial entities (stockbrokers, mutual funds) and regulatory bodies (SEBI, PFRDA, IRDAI).
• Agriculture & Labor: Improved capture of livestock data and incorporated newer employment survey metrics.

This methodological upgrade enhanced the statistical accuracy and global comparability of India’s macroeconomic data, providing a more granular reflection of a rapidly formalizing economy.
