The Ministry of Statistics and Programme Implementation (MoSPI) has released Discussion Paper 1.0 on the substitution of factories in compiling the Index of Industrial Production (IIP).
MoSPI is revising the IIP base series by updating methodologies, exploring new data sources, and consulting experts and stakeholders.
Some factories in the current panel may be non-operational or have changed production, requiring substitution to maintain continuity in the data series.
The paper outlines the proposed methodology for replacing such factories with suitable substitutes producing the same item or item group.
