India's industrial output grew by 4.9% [1] in April under a revamped Index of Industrial Production (IIP) series released Monday.
This update is significant because it synchronizes industrial tracking with the current state of the economy. By expanding the scope of measured sectors, the government aims to create a more precise input for calculating the nation's gross domestic product.
The Ministry of Statistics and Programme Implementation (MoSPI) shifted the base year for the series to FY23 (2022-23) [2]. This transition allows the government to capture a broader range of economic activity that was previously underrepresented or omitted. The new series now includes coverage for gas supply, water supply, sewerage, waste management, minor minerals, and rare earths [3].
MoSPI said the purpose of updating the base year is to ensure sync between the IIP and the evolving industrial structure [4]. The change reflects a shift toward a more modern industrial landscape, integrating sectors that have grown in importance over the last several years.
According to the ministry, the update marks the first official reading under a revised base year, which adds high-tech products and energy-related services to better reflect the modern economy [5]. The first official reading of the new series was released at 4 p.m. [6].
Manufacturing led the growth in the April figures [7]. The revised methodology is intended to provide a more accurate picture of industrial activity by removing obsolete categories and adding those that align with current production trends [3].
“Industrial output grew by 4.9% in April under a revamped Index of Industrial Production series.”
The shift to a 2022-23 base year represents a technical recalibration of how India measures its industrial health. By including high-tech products and essential utilities like waste and water management, the IIP now captures a more holistic view of the economy. This reduces the gap between reported industrial growth and actual GDP, providing investors and policymakers with data that more closely mirrors the current industrial structure.
