Economist Defends India’s Revised GDP Estimates Amid Criticism
India changed the way it calculates its economy by using newer data and a new base year.
This caused some earlier GDP numbers to be revised downward.
The newest figures showed the economy grew 7.8% in April–June 2026.
Former Finance Secretary Subhash Garg questioned why the older estimate was reduced so much.
Economist Balasubramanian said much of the change came from trade, repairs, hotels and restaurants.
He said these sectors can change a lot over many years.
He also defended a method that considers price changes for both materials and finished products.
Critics and supporters disagree about whether the revisions make current growth look better, but Balasubramanian said the overall trend is credible.
India’s real GDP grew 7.8% in April–June 2026 under the revised national-accounts series.
The April–June 2025 estimate fell from about ₹86.1 lakh crore under the old series to ₹80.3 lakh crore under the new one.
Former Finance Secretary Subhash Garg questioned whether downward revisions mechanically increased the latest growth rate.
Economist Balasubramanian said trade, repairs, hotels and restaurants accounted for much of the revision.
He defended updated data methods, including double deflation, while acknowledging that the roughly 7% revision merits examination.

Downward revisions and growth rates
Critics of the Revision
Subhash Garg questioned the sharp reduction in the April–June 2025 estimate and argued that repeated downward revisions could mechanically make current growth appear higher.
Defenders of the Revision
Balasubramanian said revisions can occur when national accounts are rebased using updated data and that the figures should be assessed alongside other macroeconomic indicators.
Size of the revision
Critics of the Revision
Critics have raised concerns about the scale of the approximately 7% revision and alleged that the informal sector may have been overestimated by about 22%.
Defenders of the Revision
Balasubramanian said comparisons of NAS 2026 and NAS 2025 indicated differences of about 3.7% in 2023–24 and 3.34% in 2022–23, smaller than some critics claim.
Double-deflation method
Critics of the Revision
Some critics question whether India should continue using double deflation, which accounts for price changes in both inputs and outputs.
Defenders of the Revision
Balasubramanian defended the approach, noting that the International Monetary Fund had recommended it and arguing that it better measures manufacturing value added.
