The Government of India has rolled out a revised framework for measuring Gross State Domestic Product (GSDP), introducing 2022-23 as the new base year for all States and Union Territories. The updated guideline, released by the Ministry of Statistics and Programme Implementation (MoSPI), aligns state-level economic calculations with the latest national accounts methodology.
The revision marks an important update to India’s regional economic data system, as most states have continued using the 2011-12 base year for GSDP calculations until now. With the latest framework, the government aims to ensure better comparability between state and national economic estimates while incorporating evolving economic structures and modern data collection practices.
Transition from the Existing 2011-12 Base Year
According to the ministry, 34 States and Union Territories currently prepare their GSDP estimates under the 2011-12 series. However, Lakshadweep and Dadra & Nagar Haveli and Daman & Diu are yet to be fully integrated into the present structure.
The revised framework seeks to create a uniform methodology across all regions, ensuring consistency in the preparation of economic statistics. Authorities stated that efforts are underway to bring all States and UTs under the updated system for more comprehensive national economic reporting.
Improved Data Sources and Methodology
The revised guidelines introduce broader use of administrative records, sector-specific databases, and survey-based information for estimating Gross State Value Added (GSVA), which forms the foundation for calculating GSDP.
Under the updated framework, GSDP will continue to be derived by adding net taxes on products to GSVA. However, the estimation methods have now been refined to better reflect structural changes in the economy, particularly in services, informal activities, and unincorporated businesses.
MoSPI noted that the revised approach is intended to improve the quality of state-level economic estimates and bring them in line with changes taking place across industries and services sectors.
Expert Committee Reviewed the New Framework
The updated methodology was reviewed by a Sub-Committee on Regional Accounts formed under the Advisory Committee on National Accounts Statistics (ACNAS). The committee was chaired by former IIM Ahmedabad professor Ravindra H. Dholakia.
The panel included representatives from the Reserve Bank of India (RBI), NITI Aayog, State governments, academic institutions, and research bodies. The committee examined concepts, methodologies, and data sources related to State Domestic Product (SDP) and District Domestic Product (DDP) estimation.
Importance of GSDP Estimates
GSDP figures play a major role in fiscal planning, inter-state comparisons, budgeting, and financial allocations. The Ministry of Finance, Finance Commission, and Comptroller and Auditor General (CAG) regularly use these estimates for policy and expenditure decisions.
The Department of Expenditure also relies on GSDP data to determine states’ borrowing limits under fiscal responsibility norms. In addition, per capita GSDP estimates are considered by the Finance Commission while recommending tax devolution among states.
Conclusion
The introduction of the revised 2022-23 base year framework represents a significant step toward modernising India’s regional economic accounting system. By updating methodologies and expanding data coverage, the government aims to improve the reliability and comparability of state-level economic estimates across the country.
Summary:
The Ministry of Statistics and Programme Implementation (MoSPI) has issued revised guidelines for all States and Union Territories to compile Gross State Domestic Product (GSDP) estimates using 2022-23 as the new base year. The updated framework replaces the older 2011-12 series and aims to improve consistency, transparency, and accuracy in regional economic calculations across India.
