**Impact Analysis**
**MoSPI and Data Source Agencies**
**Impact**
They are responsible for the expanded scope of data collection, moving from 12 to 16 source agencies to cover new sectors and products.
**Action Required**
Implement the NIC 2025 classification and collect data for the expanded item basket, including 234 item groups now reported in value terms.
**Industrial Manufacturers and Factories**
**Impact**
The reporting panel has been updated to include new products (e.g., aircraft parts, electronics) and remove obsolete items (e.g., fluorescent tubes).
**Action Required**
Relevant factories must provide accurate production data for the revised 463 item groups; new reporting units must be integrated into the data collection panel.
**Economic Analysts and Policy Makers**
**Impact**
Comparability between the old (2011-12) and new (2022-23) series is affected by changes in methodology, weights, and coverage.
**Action Required**
Users must apply the prescribed sectoral linking factors when performing long-term trend analysis and exercise caution due to the non-comparable nature of certain sectoral growth rates.

PART B: Major Changes in New Series of IIPWhat’s New
· Base year revised from 2011-12 to 2022-23.
Expanded scope & coverage by including Gas Supply, Water Supply, Sewerage, and Waste
Management activities while retaining the existing sectors.
Greater granularity by providing separate indices for
Electricity generation from Renewable and Non-renewable sources
Fuel Minerals, Metallic Minerals and Non-Metallic Minerals
· Item basket revamped to cover 463 item groups:
Additions: Cards with a magnetic stripe, CCTV camera, Articles of non-woven textiles, Parts of
aircraft and spacecraft, Stents, Vaccine (other than veterinary).
Deletions: Kerosene, Fluorescent tubes and CFLs, Tubes for bicycle/ tricycle/ rickshaw tyres.
Tubes for LMV tyres, Printing machinery, Sewing machines.
Expanded Scope & Coverage - In the new IIP series (2022–23), the coverage has been broadened by
incorporating Gas Supply and Water Supply, Sewerage & Waste Management activities, while retaining
the existing three core sectors—Mining, Manufacturing, and Electricity. In the Mining sector, the new
series includes minor minerals and rare earth minerals in addition to major minerals, making the index
more inclusive and representative of the sector. This expansion ensures that the IIP captures more
comprehensive and accurate reflection of industrial production in the economy and aligns it better with
global standards.
Enhanced Granularity –The new IIP series provides a more detailed disaggregation of industrial
activities, enabling better analysis of sectoral performance. In the Mining & Quarrying sector, the index is
now available at a more granular level, covering: (i) Fuel Minerals, (ii) Metallic Minerals, including Rare
Earth Minerals, and (iii) Non-Metallic Minerals, including Minor Minerals. This enhanced classification
offers deeper insights into the contribution and performance of different mineral categories.
Similarly, the Electricity Index is now compiled at a more disaggregated level based on the source of
electricity generation: (i) Non-Renewable Sources and (ii) Renewable Sources. This improvement allows
the index to better capture the ongoing transition towards cleaner and more sustainable energy sources,
while providing a clearer picture of changes in the energy mix over time.
Revamped Item Basket - The item basket and weights have been revised to add relevant commodities
and remove outdated ones, ensuring that each item or sector is assigned appropriate significance. The
revised basket consists of 1,042 products mapped to 463 item groups as compare to 839 items mapped to
407 item groups in 2011-12 series. This revision better captures changes in the industrial landscape,
including the emergence of new products and shifts in production patterns over time.
The number of item groups for which production data is collected in value terms have been significantly
enhanced in the new IIP series, increasing to 234 item groups as compared to 109 item groups in the old
series.
Updated Weights – The weights are updated using latest data on Gross Value Added from National
Accounts Statistics (base 2022-23) at sectoral level and Annual Survey of Industries at NIC-2/3/4 digit for
the financial year 2022-23. In Electricity sector, the weights are based on the share of each source in total
revenue generated during FY 2022–23. Whereas, in Mining & Quarrying sector, weights are updated
according to share in GVA of each mineral received from IBM and NAS for FY 2022-23.The comparison of item basket and weights of new IIP series with the old series at sectoral level is given
in table below:

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 andPetrochemicals, 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:
a. Statement IV: The Annual Growth Rates of Index of Industrial Production with base 2022-23 vis-à-
vis 2011-12: Sectoralb. 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:
a. The indices for 2022-23 have been normalize to100 at a monthly level.
b. There has been an increase in number of factories in panel for reporting data and closed ones have
been removed.
c. The item basket has been revised with inclusion of new items and exclusion of old ones.
d. 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.
e. 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.
