A monthly index that measures the volume of production across Indian industry — mining, manufacturing and electricity — relative to a chosen base year. It tracks how much is being made, not what it sells for, so it is a volume measure rather than a value one.
Who runs itCompiled and released monthly by the National Statistical Office under the Ministry of Statistics and Programme Implementation (MoSPI).
Why it is examinedA standard Prelims data point and a recurring Mains peg for questions on industrial growth, the manufacturing share of GDP, and the difference between volume and value indices.
