Source: MoSPI | PIB Delhi, 01 June 2026 | Context: GS-III — Indian Economy, Industrial Sector, Index Numbers
MoSPI released the first press release of the All India IIP under the revised base year 2022-23 (shifted from 2011-12), along with Quick Estimates for April 2026. The base year revision was undertaken under the Technical Advisory Committee for Base Year Revision of IIP (TAC-IIP), whose report was released on 25 May 2026.
April 2026: Key Metrics at a Glance
Part A: Sectoral Production Index — April 2026
| Sector | Weight (%) | Index Apr 2025 | Index Apr 2026* | Growth (%) |

Part B: Major Changes in New IIP Series (Base 2022-23)
1. Expanded Scope & Coverage
- New sectors added: Gas Supply; Water Supply, Sewerage & Waste Management — over and above Mining, Manufacturing, Electricity.
- Mining now includes minor minerals and rare earth minerals (not covered in 2011-12 series).
- Electricity index now separately compiled for Renewable (hydro, wind, solar) and Non-Renewable (thermal, nuclear) sources.
- Mining & Quarrying now disaggregated into: (i) Fuel Minerals, (ii) Metallic Minerals incl. Rare Earth, (iii) Non-Metallic Minerals incl. Minor Minerals.
- Total sectors: 4 (Mining, Manufacturing, Electricity & Gas Supply, Water & Waste).
2. Revamped Item Basket
| Parameter | Old Series (2011-12) | New Series (2022-23) |
|---|---|---|
| Total Item Groups | 407 | 463 |
| Total Products | 839 | 1,042 |
| Value-term item groups | 109 | 234 |
| Industrial Classification | NIC-2008 | NIC-2025 |
| Data Source Agencies | 12 | 16 (4 new added) |
Key Additions & Deletions in Item Basket
| Additions | Deletions |
|---|---|
| Cards with magnetic stripe | Kerosene |
| CCTV Camera | Fluorescent tubes & CFLs |
| Articles of non-woven textiles | Bicycle/Tricycle/Rickshaw tyre tubes |
| Parts of aircraft & spacecraft | LMV tyre tubes |
| Stents; Vaccines (non-veterinary) | Printing machinery; Sewing machines |
3. Updated Weights & Sectoral Comparison
| Sector | Weight: 2011-12 (%) | Item Groups: 2011-12 | Weight: 2022-23 (%) | Item Groups: 2022-23 |
|---|---|---|---|---|
| Mining & Quarrying | 14.372 | 1 | 11.053 | 3 |
| Manufacturing | 77.633 | 405 | 76.062 | 455 |
| Electricity & Gas Supply | 7.995 | 1 | 10.865 | 3 |
| Water Supply; Sewerage & Waste Mgmt | N/A | N/A | 2.020 | 2 |
| Total | 100 | 407 | 100 | 463 |
Weights updated using Gross Value Added (GVA) from NAS (base 2022-23) at sectoral level and Annual Survey of Industries (ASI) at NIC-2/3/4 digit for FY 2022-23. Electricity weights based on revenue share per source.
4. Linking Factor (2011-12 series → 2022-23 series)
Calculated using the Geometric Mean (GM) method. Linked series = Old series index ÷ Linking Factor.
| Sector | Linking Factor |
|---|---|
| Mining & Quarrying | 1.1890 |
| Manufacturing | 1.3700 |
| Electricity | 1.8495 |
| General Index | 1.3834 |
| Water Supply, Sewerage & Waste Mgmt | Not computable (new sector) |
MoSPI does not prescribe any specific method for linking; methodology choice is left to users. Growth rates of old and new series are not strictly comparable due to differences in coverage, item basket, methodology, and weighting.
5. New Source Agencies (4 Added)
- IREL (India) Limited, Dept. of Atomic Energy — for rare earth minerals.
- Directorates of Economics & Statistics (DES) of States — for minor minerals.
- Ministry of Housing & Urban Affairs (MoHUA) — for water supply & sewerage.
- Dept. of Drinking Water & Sanitation — for water supply & waste management.
6. Other Methodological Changes
- WPI used to deflate value-term item groups; will transition to Output PPI once released and stability assessed.
- NIC-2025 replaces NIC-2008 for compilation and dissemination.
- Provision for substitution of closed/non-operational factories incorporated to maintain representativeness.
- Use-Based Categories remain the same 6; individual item-group classifications reviewed & updated.

- IIP base year revised from 2011-12 to 2022-23; first press release under new series on 01 June 2026.
- New series covers 4 sectors; Water Supply, Sewerage & Waste Management is the entirely new addition.
- Item basket: 1,042 products mapped to 463 item groups vs 839 items / 407 groups earlier.
- TAC-IIP oversaw the base year revision; report released on 25 May 2026.
- Linking factor for General Index: 1.3834 (GM method). MoSPI does not prescribe a specific linking method.
- Electricity index now compiled separately for Renewable and Non-Renewable sources; weights based on revenue share in FY 2022-23.
- Next IIP release (May 2026 data): Monday, 29 June 2026.
“The revision of IIP base year from 2011-12 to 2022-23 represents a structural shift in India’s industrial measurement framework.” Critically analyse the major methodological changes and discuss their implications for tracking India’s industrial performance and policymaking.
Consider the following statements regarding the new IIP series with base year 2022-23:
- Water Supply, Sewerage and Waste Management is a newly added sector not covered in the earlier series.
- The item basket now consists of 463 item groups mapped from 1,042 products.
- MoSPI has prescribed the Geometric Mean method as the mandatory approach for linking the two IIP series.
- NIC-2025 replaces NIC-2008 for compilation and dissemination of the new IIP series.
Which of the statements given above are correct?
- (a) 1, 2 and 4 only
- (b) 1, 3 and 4 only
- (c) 2, 3 and 4 only
- (d) 1, 2, 3 and 4
Statement 3 is incorrect: MoSPI explicitly states it does not prescribe any specific method for linking; the GM method is used only for calculating the linking factor published by MoSPI, but users are free to apply their own methodology. Statements 1, 2, and 4 are factually correct as per the press release.
