India August IIP Grows 8% Under New 2022-23 Base Year Series
India's factory output grew by 8.0% year-on-year in August 2026, marking the second-fastest growth rate recorded since April 2024. The data was compiled by the National Statistical Office under the newly revised 10th IIP series with the base year shifted from 2011-12 to 2022-23.
What happened
India's industrial output, measured by the Index of Industrial Production (IIP), registered an 8.0% year-on-year expansion in August 2026. According to the Quick Estimates released by the National Statistical Office under the Ministry of Statistics and Programme Implementation, the index value rose to 123.3 in August 2026 compared to 114.2 in August 2025. This 8.0% growth marks the second-fastest pace of industrial expansion since April 2024.
The estimates reflect the newly revised 10th IIP series, which shifted the baseline from 2011-12 to 2022-23. The revision process followed recommendations of the Technical Advisory Committee for base year revision of All India IIP, chaired by Dr. Mridul K. Saggar, which submitted its report in May 2026. The new series was formally introduced on June 1, 2026, taking April 2026 as the first reference month. The updated item basket was expanded to 463 item groups covering 1,042 products, compared to 407 item groups and 839 items in the previous 2011-12 series.
Among broad sectors in August 2026, manufacturing—which holds a 76.062% weight in the revised series—expanded by 9.0%, maintaining an expansion of at least 8% for three straight months. Electricity and gas supply rose by 12.3%, while water supply, sewerage, and waste management grew by 6.3%. In contrast, mining and quarrying output contracted by 5.6% during the month. Within manufacturing, 18 of the 23 industry groups at the National Industrial Classification two-digit level posted growth, driven by electrical equipment, transport equipment, and motor vehicles.

PrepZen analysis
Base year revisions are critical milestones in Indian economic statistics. Because economic structures evolve over time, obsolete items lose relevance while newer industries emerge. The shift from 2011-12 to 2022-23 ensures the IIP reflects structural changes by incorporating rare earth minerals, gas supply, and environmental management services.
For competitive examinations like UPSC Prelims, RBI Grade B, and SSC CGL, questions on macroeconomic indicators often test institutional responsibility, base revisions, and sectoral weighting. Aspirants should note that the NSO compiles the index monthly, manufacturing constitutes the overwhelming majority of the index weight at 76.062%, and this release represents the 10th official revision since independence-era accounting.
