Quick Revision: The State-Level IIP is a monthly index tracking industrial output changes relative to a revised base year (e.g., 2022-23), with weights and item baskets updated to reflect contemporary industrial activity and ensure methodological consistency across states.

Why is this in the news?

The Ministry of Statistics and Programme Implementation (MoSPI), in collaboration with the Department of Economics and Statistics (DES), Kerala, is convening a three-day workshop in Thiruvananthapuram from 28–30 October 2026 to revise the base year of the State-Level Index of Industrial Production (IIP). This initiative aligns with the recent national-level revision of the IIP base year from 2011-12 to 2022-23, reflecting methodological upgrades to enhance the accuracy, comparability, and policy relevance of industrial output data across states.

Background

• The Index of Industrial Production (IIP) is a principal macroeconomic indicator that tracks the performance of the industrial sector, comprising mining, manufacturing, and electricity generation.
• The IIP is compiled and disseminated by state-level DES under the technical guidance of MoSPI, ensuring methodological uniformity and data quality across jurisdictions.
• The base year serves as the reference period against which changes in industrial output are measured; its revision ensures that the index reflects contemporary industrial activity rather than outdated production structures.
• The national IIP base year was revised from 2011-12 to 2022-23, incorporating methodological improvements such as updated item baskets, revised weights, expanded coverage of ancillary activities (e.g., gas supply, waste management), and enhanced factory panel data.
• State-level IIP data are critical inputs for sub-national economic planning, fiscal federalism, and the design of industrial policies tailored to regional industrial ecosystems.
• The workshop in Thiruvananthapuram will focus on aligning Kerala’s state-level IIP with the revised national framework, ensuring consistency in data reporting and policy analysis.

What is the State-Level Index of Industrial Production (IIP)?

• The IIP is a monthly measure of the physical volume of industrial output, expressed as an index relative to a base year, where the base year is assigned a value of 100.
• It is constructed using a weighted average of production quantities from three broad industrial sectors: mining (weight: ~14%), manufacturing (weight: ~77%), and electricity (weight: ~8%).
• The index is disaggregated into use-based categories—basic goods, capital goods, intermediate goods, consumer durables, and consumer non-durables—to analyse demand-side dynamics.
• The IIP serves as a leading indicator for assessing short-term industrial trends, informing monetary and fiscal policy decisions, and guiding investment strategies.
• At the state level, the IIP is compiled by DES using factory-level data, administrative records, and survey-based inputs, with MoSPI providing methodological oversight to ensure national comparability.
• The base year revision involves updating the item basket (to reflect current industrial structure), revising weights (to reflect relative importance of sectors), and incorporating new data sources or activities (e.g., waste management) to improve coverage.
• The IIP is published by MoSPI with a lag of six weeks, enabling policymakers to monitor industrial performance and adjust economic strategies accordingly.
• The workshop in Thiruvananthapuram will finalise the state’s item basket, weights, and factory panel for the revised IIP, while also aligning with the National Industrial Classification (NIC)-2025 and National Product Classification (NPC) revisions.
