INDEX OF INDUSTRIAL PRODUCTION (IIP)
It is an index that tracks manufacturing activity in different sectors of an economy. The IIP number measures the industrial production for the period under review, usually a month, as against the reference period.
Mining, manufacturing, and electricity are the three broad sectors in which IIP constituents fall.
Core sectors (Electricity, crude oil, coal, cement, steel, refinery products, natural gas, and fertilizers) constitute 40% of the weight of items included in the IP.
IIP data is also compiled and published by the MOSPI.
