India’s factory output growth decelerated to 4.9% in April 2024, according to the latest government data released this week, marking the first report published under a revised base year of 2022-23. The Index of Industrial Production (IIP) indicates a cooling trend compared to the 5.7% expansion observed in April 2025, reflecting shifting dynamics in the nation’s manufacturing landscape.
Understanding the Base Year Revision
The Ministry of Statistics and Programme Implementation recently shifted the IIP base year from 2011-12 to 2022-23 to better capture the evolving structure of the domestic economy. This technical adjustment aims to provide a more accurate representation of current industrial activity by updating the basket of goods and services included in the index.
Economists note that base year revisions are standard practice to ensure that economic indicators remain relevant to modern production patterns. By incorporating new industries that have emerged over the last decade, the government intends to offer a clearer, albeit more conservative, view of industrial health.
Analyzing Industrial Performance
The slowdown in April suggests a moderation in momentum across key sectors, including mining, manufacturing, and electricity generation. While industrial activity remains in positive territory, the dip from previous highs reflects broader challenges in global demand and domestic consumption patterns.
Data points from the report highlight that the manufacturing sector, which holds the largest weight in the index, continues to navigate supply chain fluctuations. Analysts have pointed out that while the headline number shows a deceleration, the underlying shift in constituent weights makes direct comparisons to previous years complex.
Expert Perspectives on Growth Trends
Market experts suggest that the 4.9% growth rate should be viewed as a period of consolidation following a year of high-frequency expansion. The transition to the new 2022-23 base year effectively reweights the influence of traditional heavy industries against newer, technology-driven manufacturing sectors.
