Index of Industrial Production (IIP)

The IIP is a composite indicator that measures short-term changes in the volume of production in the industrial sector of an economy. In India, it is compiled and released monthly by MoSPI, with a six-week lag from the reference month. The index uses the Laspeyres formula — a weighted average of output quantities relative to a base year — where weights are derived from Gross Value of Output (GVO) at the 5-digit NIC level and Gross Value Added (GVA) at higher aggregation levels using Annual Survey of Industries (ASI) data.

Key details

Compiled by: MoSPI (Ministry of Statistics and Programme Implementation)
Previous base year: 2004-05 (revised to 2011-12 in May 2017)
New base year: 2022-23 (effective June 1, 2026)
Release frequency: Monthly (six-week lag)
Three broad sectors: Mining and Quarrying, Manufacturing, Electricity (now extended to include Water Supply, Sewerage and Waste Management)
Eight Core Industries: Coal, Crude Oil, Natural Gas, Refinery Products, Fertilisers, Steel, Cement, Electricity — these have a combined weight of ~40% in IIP
