Index of Industrial Production

Index of Industrial Production

• The Index of Industrial Production (IIP) is an index that indicates the performance of various industrial sectors of the Indian economy.
• It is calculated and published by the Central Statistical Organisation (CSO) every month.
• It is a composite indicator of the general level of industrial activity in the economy.

Official Definition – As given by CSO

“It is a composite indicator that measures the short-term changes in the volume of production of a basket of industrial products during a given period with respect to that in a chosen base period.”

IIP – Explanation

• This index gives the growth rates of different industry groups of the economy over a specified time period.
• The industry groups that it measures are classified under the following:
  • Broad sectors like manufacturing, mining, and electricity.
  • Use-based sectors like capital goods, basic goods, intermediate goods, infrastructure goods, consumer durables, and consumer non-durables.
• The eight core industries of India represent about 40% of the weight of items that are included in the IIP. 
• The Eight Core Sectors/Industries are:
  • Electricity
  • Steel
  • Refinery products
  • Crude oil
  • Coal
  • Cement
  • Natural gas
  • Fertilizers
• The United Nations Statistics Division (UNSD) recommends including quarrying, gas steam and air-conditioning supply, sewerage, water supply, waste management, and remediation in the broad sectors. But this is not done due to the problems in data availability on a monthly basis for all these sectors. So, the data has been restricted to mining, electricity, and manufacturing.

Index of Industrial Production Importance

• The Index is used by government agencies and departments such as the Finance Ministry and the RBI for policymaking.
• It is also used for estimating the Gross Value Added of the manufacturing sector quarterly.
• Also, the Index is used by business analysts, financial experts, and the private industry for multiple purposes.
• It is the only measure of the physical volume of production.
• It is also extremely useful for the projection of advance GDP estimates.

• Any index is to be subject to changes and modifications like changing the base year, including more items in the basket, etc.
