About IIP

• The Index of Industrial Production (IIP) is an 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.
• Mining, manufacturing, and electricity are the three broad sectors in which IIP constituents fall.
• It is compiled and published every month by the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation.
• The current base year is 2011-2012.
• The Eight Core Industries (Coal, Crude Oil, Natural Gas, Refinery Products, Fertilizers, Steel, Cement and Electricity) comprise 40.27 per cent of the weight of items included in the IIP.

Why in News?

• Growth in industrial activity in the country, measured by the Index of Industrial Production (IIP) slowed to an eight-month low of 2.7% in April 2025, dragged down by lower activity in several sectors, including mining and quarrying, electricity, primary goods, infrastructure and construction, and consumer non-durables.
