Phase IFoundation

Background

Overview

Understanding industrial production measurement is vital for analyzing economic performance, formulating industrial policies, and assessing the impact of government initiatives on manufacturing and employment. It is a frequently asked topic in both Prelims and Mains for economic analysis.

The measurement of industrial production is crucial for assessing the health of the manufacturing sector, a key driver of economic growth and employment. In India, the Index of Industrial Production (IIP) serves as a composite indicator that measures the short-term changes in the volume of production of a basket of industrial products.

  • Compiled monthly by NSO under MoSPI.
  • Current base year: 2011-12.
  • Covers Manufacturing, Mining, and Electricity sectors.
  • Eight Core Industries contribute significantly to IIP.

Elimination traps

Authority vs ministry — Distinguish between NSO (the body) and MoSPI (the ministry) responsible for IIP compilation and release.

Ministry sets policy; regulator often has quasi-judicial powers.
