Release of Discussion Paper 3.0: Seasonal Adjustment of Index of Industrial Production

Posted On: 28 JAN 2026 5:05PM by PIB Delhi

The Ministry of Statistics and Programme Implementation (MoSPI) is undertaking the base revision exercise of the Index of Industrial Production (IIP). In the process, MoSPI is revisiting methodologies, exploring new data sources and incorporating changes after comprehensive consultations with the experts, academicians, users and other stakeholders.

Although, industrial production is significantly influenced by seasonality and calendar effects, India has not attempted to publish seasonally adjusted IIP series so far and users were expected to undertake such analysis separately using methods and tools of their choice.  However, in light of an increasing demand for a seasonally adjusted IIP among users, MoSPI has prepared a Discussion Paper 3.0: Seasonal Adjustment of Index of Industrial Production which outlines the proposed methodology for seasonal adjustment of IIP.

MoSPI invites views and comments from experts, academicians, Central government Ministries/ departments, State governments, financial institutions and other stakeholders on the proposed methodology.

The Discussion Paper is available on the MoSPI website www.mospi.gov.in. Comments and suggestions may be sent to iipcso[at]nic[dot]in by 12th February, 2026.
