The Infrastructure Output index measures the annual change in the production volume of eight core industries in India, including coal, crude oil, natural gas, refinery products, fertilizers, steel, cement, and electricity. These sectors account for approximately 40% of the weight of items included in the Index of Industrial Production (IIP). It serves as a lead indicator for the overall industrial performance and economic health of the Indian economy. High growth in these sectors typically suggests robust demand and future expansion in manufacturing and construction.
The index is calculated using the Laspeyres formula, comparing the current production quantities of the eight core industries against a fixed base year. Each industry is assigned a specific weight based on its relative importance in the overall industrial structure of India.
