Overview The Ministry of Statistics and Programme Implementation (MoSPI) will release a refreshed series of national‑accounts data on 27 February 2026 . The overhaul introduces a new base year, refined sector‑wise methods and fresh data sources such as GST , to make GDP and GVA estimates more accurate and granular. Key Developments Base year shifted from 2011‑12 to 2022‑23 , aligning estimates with the current structure of the economy. Sector‑wise methodology upgraded: corporate GVA now allocated on activity‑wise revenue share rather than a single dominant sector. General government accounts now include the value of housing services provided to government employees and expanded coverage of autonomous institutes and local bodies. Household sector measured annually using ASUSE and PLFS , eliminating reliance on extrapolation. Private final consumption expenditure estimated with finer detail through Household Consumer Expenditure Surveys and direct production data. GST data leveraged to map regional output of private corporations, identify active firms and improve valuation of non‑reporting entities. State‑level data enriched via better reporting from local bodies; banking activity derived from the STRBI of the RBI and actual NBFC financials from the Ministry of Corporate Affairs. Important Facts The new series adopts a double‑deflator technique to capture price movements more accurately. In agriculture, inputs from specialised research institutes (e.g., Inland Grassland and Fodder Research Institute) are now incorporated, enhancing sectoral precision. Insurance agents and gross fixed capital formation of the unincorporated sector, previously under‑reported, are better captured through improved ASUSE utilisation. UPSC Relevance Understanding these methodological shifts is vital for GS‑3 (Economy) questions on national‑account reliability, growth measurement and fiscal policy impact. The inclusion of GST data illustrates how tax administration feeds macro‑economic indicators, a frequent topic in essay and answer‑type questions. The expanded coverage of informal and government‑housing services highlights the evolving definition of economic activity, relevant for discussions on inclusive growth and public‑sector efficiency. Way Forward Future releases are expected to refine sectoral estimates further as more granular data become available. Aspirants should monitor subsequent bulletins for changes in sector‑wise growth rates, especially in services and agriculture, and assess how these revisions affect India’s growth trajectory and policy discourse.
