India GDP Base-Year Revision Triggers Political Growth Data Storm
GDP is a way to measure how much an economy produces.
The government said India grew by 7.8% in the April-June 2026 quarter.
Congress questioned whether the number looks high partly because the government changed the comparison year used in its calculations.
That comparison year is called the base year.
India changed it from 2011-12 to 2022-23.
The government says this makes the numbers more up to date and uses better information.
Critics say the change may have lowered earlier figures and made current growth look larger.
The debate has become political, with Prime Minister Narendra Modi praising the result and Congress challenging it.
Economist Raghuram Rajan said the strong figures should be examined alongside weak job creation and limited private investment.
The government reported real GDP growth of 7.8% in April-June 2026, exceeding economists' forecasts.
Congress questioned whether changes to the GDP base year and previous estimates made growth appear stronger.
India changed its GDP base year from 2011-12 to 2022-23 on 27 February.
The government said rebasing improves methods, incorporates newer data and better reflects economic changes.
Raghuram Rajan said strong GDP growth had not clearly translated into private investment, foreign investment or decent jobs.

Congress and Critics
Meaning of the base-year revision
Government and Supporters
The government says rebasing is a routine statistical exercise that updates methods, adds better data sources and reflects structural changes in the economy.
Congress and Critics
Congress argues that lowering the comparison base can make the current growth rate appear substantially higher without a corresponding change in economic activity.
Interpretation of 7.8% growth
Government and Supporters
Prime Minister Narendra Modi called the 7.8% growth an exemplary and herculean achievement made despite global disruptions and supply-chain challenges.
Congress and Critics
Congress questioned the basis of the calculation and raised concerns about revisions to earlier GDP figures, inflation estimates, manufacturing and private consumption.
Growth and economic outcomes
Government and Supporters
The reported figures indicate strong annual and quarterly economic growth, with the quarterly result exceeding economists' expectations.
