<h1>GDP calculation revamp raises official growth estimate and restructures sectoral measurement, affecting fiscal and policy benchmarks.</h1> A methodological overhaul adopting a 2022-23 base year revises GDP computation by introducing double deflation for manufacturing and agriculture, replacing single deflation, and shifting household estimation to regular surveys. The new series integrates administrative sources (GST, PFMS, vehicle data) to better capture informal and fast growing sectors, producing upward revisions to headline real and nominal growth rates, altering sectoral contributions-notably manufacturing and services-and changing fiscal deficit and policy benchmarks that require recalibration of prior forecasts.
