New Series of GDP, CPI and IIP Release Schedule Announced for 2026

The Ministry of Statistics and Programme Implementation has detailed the timetable for publishing the revised series of Gross Domestic Product, Consumer Price Index and Index of Industrial Production for 2026, together with the methodological upgrades that underpin the revisions. 

Release Dates and Base Year Changes 

The new GDP series will be published on 27 February 2026, the revised CPI series on 12 February 2026, and the updated IIP series in May 2026.  

The base year for both GDP and IIP has been shifted to 2022 to 23, while the CPI base year has been moved to 2024. These changes are intended to improve relevance, accuracy, and international comparability. 

Methodology and Survey Enhancements 

Technical Advisory Committees comprising experts from academia, central and state governments and the RBI guide the revision process. Methodological improvements include updated weighting, incorporation of recent survey data, and refined sampling designs.  

Sample sizes have been increased, and survey instruments modified for the Periodic Labour Force Survey, Household Consumption Expenditure Survey and Annual Survey of Unincorporated Sector Enterprises.

Transparency Measures 

MoSPI has introduced digital platforms with built‑in validation for data collection, reducing processing time. An Advance Release Calendar is now available on the ministry website. The e Sankhyiki portal provides unit‑level data for researchers and policymakers.  

Regular dialogues with data users are held to incorporate feedback, and a National Meta Data Structure has been circulated to clarify data sources and collection methods. 

Conclusion 

The scheduled releases in February and May 2026 mark the rollout of revised statistical series with updated base years and enhanced methodological rigour. The ministry’s transparency initiatives aim to strengthen confidence in official statistics.
