India's 2026 GDP data revision is about methods, not growth rates

Discussion papers published by the statistics ministry should cue debates on what India can reasonably expect to measure

Following the release of two discussion papers by India's ministry of statistics outlining proposed methodological changes for the upcoming base-year revision of national accounts, there has been a renewed focus on our methodology for the GDP revision.

The new base year will be 2022-23 and the revised series is scheduled for release in early 2026. They lay out, in great detail, what has changed in data availability and show improvements in methodology.

It is precisely for these reasons that they deserve attention. They do not settle our perennial and politicized debates about India's 'true' growth rates. Instead, they represent a significant step in how the statistical system explains itself to users, while also giving us the tools to understand what constraints remain.

On the positive side, these revisions build on previous efforts and incorporate newer data available since the 2011 series to move away from blunt proxies and static ratios. On the production side, the expanded use of corporate filings (via MGT 7/7A forms filed with the ministry of corporate affairs), enables a more efficient allocation of value added across activities, rather than assigning multi-activity firms wholesale to a single dominant sector. The use of India's Annual Survey of Unincorporated Sector Enterprises (ASUSE) and Periodic Labour Force Survey (PLFS) makes household sector estimates more dynamic than the practice of using proxies for growth on base-year estimates. In the past, such simplifications were unavoidable; today, richer administrative and survey data permit more granular treatment. These changes will not lead to higher or lower growth, but will improve consistency.
