Does frequent revision of baseline economic data undermine confidence in India's official growth figures?
Former Indian Finance Secretary Subhash Chandra Garg challenged official Q1 GDP figures, highlighting a discrepancy between calculation methods. Garg calculated a growth rate of 2.6% by comparing an earlier nominal GDP estimate of roughly ₹86.05 lakh crore for Q1 FY25–26 directly against the latest Q1 FY26–27 nominal GDP figure of ₹88.27 lakh crore. However, the Ministry of Statistics and Programme Implementation reports official real GDP growth at 7.8%, using revised comparable real GDP estimates of ₹75.46 lakh crore and ₹81.36 lakh crore. The divergence highlights how a ₹6 lakh crore downward revision to baseline data and the mixing of statistical vintages can create vastly different interpretations of economic performance.
Comparing unrevised historical nominal GDP with current figures yields a 2.6% growth rate.
The government's official real GDP growth rate is calculated at 7.8% using comparable baseline figures.
The initial nominal GDP estimate for Q1 FY25–26 was reduced significantly in later revisions.
Whether future data revisions will materially alter the current 7.8% official real growth estimate.
