The Ministry of Statistics and Programme Implementation (MoSPI) has revised the base year of the All India Index of Industrial Production (IIP) from 2011–12 to 2022–23 with the objective of making the index more representative of the current structure and dynamics of the industrial sector. The revised series incorporates an updated item basket, a revised weighting structure, and enhanced sectoral coverage to better capture recent developments in industrial activity across the economy.

The base year revision exercise was undertaken under the aegis of the Technical Advisory Committee for Base Year Revision of the All India Index of Industrial Production (TAC-IIP). The Committee's report was released on 25 May 2026, laying the foundation for a more robust, relevant, and comprehensive measure of industrial production in India.

For the new All India Index of Industrial Production (IIP) series, this press release is structured into two parts:

 

Part A	Quick Estimates of Index of Industrial Production and Use- Based Index for the Month of April 2026 (Base 2022-23=100)
Part B	Major Changes in New Series of IIP

• The six Use-Based Categories of the 2011-12 series will continue in the new series of IIP. Though, the categories themselves were not changed; individual item groups classifications were reviewed in detail and updated under the Use-Based Category.
• In the new IIP series with base year 2022-23, the practice of using the Wholesale Price Index (WPI) to deflate item groups for which production data is reported in value terms will continue. The Output PPI will be used once it is released, after examining its stability.
• The National Industrial Classification 2025 will be used in the compilation and dissemination of the new series.
• Provision for Substitution of Factories that have closed down or become non-operational during the currency of the series has been incorporated in the new IIP series, which will maintain representativeness and reliability of the index.
• In the new series of IIP with base year 2022-23, there are total 16 data Source Agencies. The existing source agencies for compilation of IIP include the i) Indian Bureau of Mines, ii) Directorate of Sugar and Vegetable Oils, iii)Tea Board India, iv) Office of the Textile Commissioner, v) Office of the Jute Commissioner, vi) Ministry of Petroleum and Natural Gas, vii) Ministry of Steel, viii) Railway Board, ix) Department for Promotion of Industry and Internal Trade, x) Department of Chemicals and Petrochemicals, xi) Department of Fertilisers and xii) Central Electricity Authority. The new source agencies introduced in the new series include xiii) IREL (India) Limited, Department of Atomic Energy for rare earth minerals xiv) Directorates of Economics and Statistics (DES) of States for minor minerals, and xv) Ministry of Housing and Urban Affairs (MoHUA) and xvi) Department of Drinking Water & Sanitation for the newly included activities relating to water supply, sewerage and waste management.
• Linking Factor:

It is provided at sectoral level to link the new series with previous IIP series. The linking factor is calculated using the Geometric Mean (GM) method as follows:

The linked series is obtained by dividing the indices of old series with the coefficient (linking factor) calculated above.

• At lower levels of disaggregation, the item basket changes significantly between base years due to the inclusion of new products and the dropping of obsolete ones. Therefore, deriving linking factors at lower level may not yield reliable results.

Linking Factor for linking 2011-12 series with 2022-23 series are given in the below table:

S. No.	Sector	Linking Factor
1	Mining & Quarrying	1.1890
2	Manufacturing	1.3700
3	Electricity	1.8495
4	General	1.3834

 

• Since there has been an expansion in the scope of IIP in the new series with base year 2022-23, there may not be a direct correspondence between the two series. The new sector, namely water supply, sewerage & waste management, in the all-India IIP with base year 2022-23, was not covered in the earlier series. Hence, linking factor for the same cannot be computed. Although, the linking factor for the general index is being provided, users may exercise caution while comparing the indices of the two series.
• It may be noted, as matter of policy, MoSPI does not prescribe any specific method for linking or converting indices from one series to another. The choice of methodology for linking the series is left to the users, depending on their analytical requirements.

• Comparative Annual Growth Rates in Overlapping Period of 2022-23 series and 2011-12 Series:

Based on monthly production figures provided by the source agencies from April 2022 till April 2026, the annual growth rates were compiled and presented in following statements:

1. Statement IV: The Annual Growth Rates of Index of Industrial Production with base 2022-23 vis-à-vis 2011-12: Sectoral
2. Statement V: The Annual Growth Rates of Index of Industrial Production with base 2022-23 vis-à-vis 2011-12: Use Based

While comparing the new IIP series with the old series, users may note that differences in coverage, methodology, item basket, sectoral composition and weighting structure have affected the comparability of growth rates across the two series. The growth rates of the two series are not strictly comparable due to following reasons:

1. The indices for 2022-23 have been normalize to100 at a monthly level.
2. There has been an increase in number of factories in panel for reporting data and closed ones have been removed.
3. The item basket has been revised with inclusion of new items and exclusion of old ones.
4. The electricity sector has undergone significant changes in the new series. Unlike the old series, which covered only electricity generation, the new series includes both Electricity & Gas Supply activities. Further, while the old series used total electricity generation from all sources as a single indicator, the new series compiles the electricity index as a weighted index of electricity generated from two different sources Renewable (hydro, wind and solar) and Non-Renewable (thermal, nuclear). The weights are based on the share of each source in total revenue generated during FY 2022–23.
5. The coverage and composition of the Mining & Quarrying sector have undergone significant changes in the new series. The new series includes minor minerals and rare earth minerals, which were not covered in the old series. The inclusion of minor minerals has a substantial impact on the growth pattern of the sector, as these minerals account for a significant share in GVA of the total Mining & Quarrying sector as per National Accounts estimates for 2022–23. In addition, the weights of common minerals have also been revised in the new series. Therefore, growth rates of the Mining & Quarrying sector in the old and new series are also not strictly comparable.

• The detailed tables including indices at Sectoral level, Manufacturing NIC-2-digit level, Sub-sectoral level of Mining & Quarrying, Electricity & Gas Supply, Water Supply, Sewerage & Waste Management and as per Use-Based Classification for new series from April 2023 onwards are available at e-Sankhyiki Portal (MoSPI) through below link:

The IIP 2022-23 series marks a significant strengthening of India’s industrial production measurement framework. With updated base year, revised item basket and weights, improved sectoral coverage, and enhanced use of data sources, the new series provides a more representative, reliable, and methodologically robust measure of industrial growth, aligned with evolving economic structures and international best practices.
