Index of Industrial Production (IIP)

Context:

India’s Index of Industrial Production (IIP) registered a 3.5% growth in July, a four-month high. The data came a day after the U.S., India’s largest trading partner, operationalised 25% penalty tariffs on Indian goods, citing continued oil purchases from Russia.

What it is:

• A composite indicator that measures the short-term changes in the volume of production of a basket of industrial goods.
• Serves as a key economic indicator for measuring the level of industrial activity in the country.

Released by:

• National Statistical Office (NSO), Ministry of Statistics and Programme Implementation (MoSPI).
• Released monthly (with a time lag of 6 weeks).

Base Year:

• 2011-12 (latest base year).
• The base year is the reference period used to measure the current performance of industrial production. 

Components of IIP:

IIP has two types of classification:

1. Sectoral Classification (3 Sectors):
   • Manufacturing (77.63% weight)
   • Mining (14.37% weight)
   • Electricity (7.99% weight)
2. Use-Based Classification (6 Categories):

Limitations:

• Only reflects volume of production, not value.
• Monthly volatility due to seasonality and short-term factors.
• Time lag reduces its real-time usefulness.
