- A key statistical indicator measuring short-term changes in the volume of production across major industrial sectors.
- It reflects the growth or contraction of industrial activity and serves as a vital gauge of economic health.

Base Year: 2011–12 (current base year)
Sectoral Composition of IIP (with weights):
| Sector | Weight (%) | Number of Items |
| Manufacturing | 77.63% | 809 |
| Mining | 14.37% | 29 |
| Electricity | 7.99% | 1 |
Eight Core Industries (Total Weight in IIP: 40.27%)
Listed in decreasing order of weight:
- Refinery Products
- Electricity
- Steel
- Coal
- Crude Oil
- Natural Gas
- Cement
- Fertilisers
Note: These industries are considered the backbone of industrial activity and heavily influence overall IIP performance.
As per the revised calendar, the Quick Estimate of Index of Industrial Production (IIP) will now be released on 28th of every month (or next working day if 28th is a holiday)
Industrial Growth – April 2025 (Index of Industrial Production)
Overall Performance
- Industrial growth slowed to 7% in April 2025, the lowest in 8 months.
- Last recorded slower growth was in August 2024 when IIP growth was 0%.
- The slowdown was driven by weak performance in:
- Mining and quarrying
- Electricity
- Primary goods
- Infrastructure and construction
- Consumer non-durables
Sector-wise Performance
- Mining and Quarrying:
- Contracted 2%
- Worst performance since August 2024
- Electricity:
- Growth slowed to 1.1%
- Lowest in 8 months
- Primary Goods:
- Contracted by 4%
- Eight-month low
- Manufacturing:
- Grew by 4%
- Three-month high
- Consumer Non-Durables:
- Shrunk by 7%
- Third consecutive month of contraction
- Contracted in 4 of the last 5 months
Positive Highlights
- Capital Goods:
- Grew by 3%
- Strongest growth among sectors
- Low base effect from April 2024 (2.81%)
- Growth driven by electrical and non-electrical machinery
- Seen as a potential indicator of investment revival
- Consumer Durables:
- Growth accelerated to 4%
- Highest in 3 months
- Supported by:
- Rabi crop success
- Marriage season
- Auto sector (15.4% growth)
