- Change in Default GDP from the GDP at Factor Cost to GDP at Market Prices.
Change in GDP methodology
- Sector wise estimates using GVA at Basic Prices i.e., GDP at Factor Cost + Production Taxes – Production Subsidies.
- Calculation of GDP: GVA at basic prices + Product Taxes – Product subsidies.
- Change in database from Annual Survey of Industries (ASI) to MCA-21 database of Ministry of Corporate affairs
- Improved coverage of financial corporations through information provided by SEBI, PFRDA, IRDA etc.
- Some economists have highlighted that these changes have inflated GDP numbers by around 2.5% on account of – Change in default GDP, Presence of shell firms(38%) in MCA database etc. However, Eco Survey 2018-19 has highlighted that these concerns are unfounded.
