MoSPI releases GDP methodology report for new 2022-23 base year series
Synopsis
India's statistics ministry has released the full methodological playbook behind its new GDP series, pulling back the curtain on how the country measures its own economy. From replacing a decades-old benchmarking method with the Proportional Denton approach to leaning on GST data and two large household surveys, the changes signal a meaningful leap in transparency and statistical rigour for national accounts.
Key Takeaways
MoSPI released its consolidated methodology publication for India's new National Accounts Statistics series on 21 September 2026 .
The new series carries a base year of 2022-23 and was first released in February 2026 , with an update on 31 August 2026 .
Household sector GDP is now estimated directly from two MoSPI surveys: ASUSE and PLFS .
Quarterly GDP compilation has shifted to the Proportional Denton benchmarking approach , with greater use of GST and administrative data.
PFCE now adopts the UN COICOP 2018 classification, supported by more granular data sources.
MoSPI consulted the IMF and incorporated UN-recommended methodologies in the revision process.
The Ministry of Statistics and Programme Implementation (MoSPI) on Monday, 21 September 2026, released a consolidated publication detailing the data sources, methodologies, and compilation practices underpinning India's new National Accounts Statistics (NAS) series, which carries a base year of 2022-23. The publication is intended to serve as a definitive reference for policymakers, researchers, and analysts seeking to understand how key macroeconomic aggregates — including Gross Domestic Product (GDP), National Income, and Savings — are compiled under the revised framework.
Background and Context
The new national accounts series with the 2022-23 base year was first released in February 2026, replacing the previous base year. The series was subsequently updated on 31 August 2026 to incorporate revisions stemming from the release of the updated Producer Price Index (PPI) and Index of Industrial Production (IIP) in June. Monday's methodological publication consolidates the statistical framework behind those releases into a single, publicly accessible document.
Key Methodological Changes
A central theme of the publication is the modernisation of estimation approaches across the corporate, financial, government, and household sectors. For the Non-Financial Private Corporate (NFPC) sector, MoSPI has drawn on corporate filings, Limited Liability Partnership (LLP) records, and enhanced company-level data to sharpen industry classification, better measure economic activity, and allocate output across multiple business segments.
In the household sector, direct estimation has been adopted from two MoSPI surveys — the Annual Survey of Unincorporated Sector Enterprises (ASUSE) and the Periodic Labour Force Survey (PLFS) — after evaluating several alternative approaches. For the General Government sector, changes include expanded institutional coverage, refined treatment of pension payments, and the incorporation of housing facilities provided to government employees.
Expenditure-Side and Quarterly Improvements
Private Final Consumption Expenditure (PFCE) now adopts the Classification of Individual Consumption According to Purpose (COICAP) 2018 framework recommended by the United Nations, supported by more granular consumption data and administrative sources. Compilation methodologies for construction, agriculture, livestock, forestry, and services have also been revised for greater consistency with current economic realities.
For Quarterly National Accounts, the existing benchmarking method has been replaced with the Proportional Denton approach, and the use of Goods and Services Tax (GST) data and other administrative sources has been significantly increased. The publication also includes methodology for compiling Supply Use Tables (SUT) and guidelines for Regional Accounts.
International Alignment and Expert Consultations
MoSPI has incorporated recommendations from expert committees and held detailed consultations with the International Monetary Fund (IMF) on various aspects of the base year revision. UN-recommended methodologies have also been embedded into the framework. The ministry described the publication as laying the methodological foundation for a more robust, transparent, and data-driven national accounting system that better reflects the evolving structure of the Indian economy.
Who Will Use This Document
The publication is expected to serve policymakers, academic researchers, financial analysts, and international institutions that rely on India's national accounts data. By making the full compilation framework publicly available, MoSPI aims to promote greater transparency and understanding of how India measures its economic output. Going forward, the document will also guide state-level statistical offices in aligning their Regional Accounts compilation with the new national methodology.
Point of View
Granular, and hard to manipulate, making it a far sturdier anchor than the proxy indicators it replaces. The household sector reform is equally telling — ASUSE and PLFS data directly measure the unorganised economy rather than extrapolating from corporate proxies. Whether this raises or lowers India's official growth numbers matters less than the fact that the methodology is now defensible in international peer review.

Frequently Asked Questions
What is the MoSPI GDP methodology publication released in September 2026?
It is a consolidated document released by the Ministry of Statistics and Programme Implementation (MoSPI) on 21 September 2026, detailing the data sources, compilation practices, and methodologies used in India's new National Accounts Statistics series with a 2022-23 base year . It covers GDP, National Income, PFCE, Gross Fixed Capital Formation, and Savings.
Why has India revised its GDP base year to 2022-23?
Base year revisions are periodically carried out to update the reference point for economic measurement so that it better reflects the current structure of the economy. The 2022-23 base year revision incorporates improved data sources — including GST data, corporate filings, and two household surveys — and aligns with international statistical standards recommended by the IMF and UN.
What is the Proportional Denton approach now used for quarterly GDP?
The Proportional Denton approach is an internationally recognised statistical benchmarking technique that ensures quarterly GDP estimates are consistent with annual totals while preserving the movement of quarterly indicators. MoSPI has replaced its previous benchmarking method with this approach to improve the accuracy and international comparability of India's quarterly national accounts.
How has MoSPI improved household sector GDP estimation?
MoSPI has adopted direct estimation from the Annual Survey of Unincorporated Sector Enterprises (ASUSE) and the Periodic Labour Force Survey (PLFS) for the household sector, replacing earlier proxy-based approaches. This gives a more direct statistical read on the unorganised economy, which accounts for a substantial share of India's output.
Who is this publication meant for?
The publication is intended as a reference document for policymakers, researchers, financial analysts, academics, and international institutions. It is also expected to guide state statistical offices in aligning regional accounts compilation with the new national methodology.
