The Ministry of Statistics and Programme Implementation (MoSPI) is releasing a new series of National Accounts Statistics (NAS) with 2022–23 as the base year, replacing the 2011–12 base year. The revised series aims to improve the accuracy and granularity of estimates of Gross Domestic Product (GDP) and Gross Value Added (GVA), reflecting structural changes in the Indian economy over the past decade.

Rationale for Revision

Since the previous base year revision in 2015, India’s economy has undergone significant transformations:

• Expansion of the digital economy and e-commerce
• Increased formalisation following the GST regime
• Shifts in consumption, employment, and production patterns
• Rapid growth of financial and service sectors

Updating the base year ensures better measurement of real growth, improved sectoral representation, and stronger evidence-based policymaking.

Key Structural Improvements

1. Sectoral Measurement Reforms

• Private Corporate Sector: Earlier, a company’s entire GVA was attributed to its dominant sector. The new approach allocates GVA based on activity-wise revenue shares, improving sectoral accuracy.
• General Government Sector: Inclusion of housing services provided to government employees and better coverage of local bodies and autonomous institutions enhances government output estimation.

2. Better Estimation of the Household Sector

The household sector—one of India’s largest contributors to GVA—will now be estimated using annual data from:

• Annual Survey of Unincorporated Sector Enterprises (ASUSE)
• Periodic Labour Force Survey (PLFS)

This replaces earlier extrapolation methods with direct annual estimation.

3. Improved Consumption Estimates

Private Final Consumption Expenditure (PFCE) will be derived from:

• Household Consumer Expenditure Surveys
• Production-side data
• Administrative datasets

This strengthens measurement of domestic demand.

Integration of Administrative Data

• Expanded use of GST data for regional output estimation and corporate value addition.
• Identification of active companies through tax records.
• Use of RBI’s Statistical Tables Relating to Banks in India (STRBI) for banking sector estimates.
• Replacement of proxy methods for private NBFCs with actual financial data from the Ministry of Corporate Affairs.

These changes improve financial sector GVA estimation and reduce reliance on assumptions.

Informal Sector and Agriculture

Greater use of ASUSE improves coverage of informal enterprises, insurance agents, and Gross Fixed Capital Formation (GFCF) in the unincorporated sector.

Agriculture estimation is strengthened using updated methodologies and data from institutions such as:

• Central Marine Fisheries Research Institute
• Central Inland Fisheries Research Institute
• Grassland and Fodder research bodies

This improves measurement of livestock, fisheries, and fodder output.

Methodological Upgrade: Double Deflation

One of the most significant reforms is the shift from a single deflator to a double deflator method.

• Earlier: Same inflation rate applied to inputs and outputs, causing growth distortions.
• Now: Separate deflators for inputs and outputs, ensuring more accurate real GVA estimates.

This reduces statistical discrepancies and improves credibility.

Additionally, Supply and Use Tables (SUTs) will be integrated, improving consistency between production and expenditure approaches.

International Alignment

India currently follows the System of National Accounts (SNA 2008). With the UN adopting SNA 2025, India plans to align with updated global standards in future revisions.

Challenges

• Complexity of double deflation and data integration.
• Back-series reconstruction may take nearly a year.
• State-level data quality variations.
• Need for greater transparency to avoid credibility debates seen in past revisions.

Conclusion

The 2022–23 base year revision represents one of India’s most comprehensive statistical overhauls in over a decade. By integrating richer datasets, modern methodologies, and improved sectoral coverage, the new GDP series aims to enhance policy reliability and international comparability. Its success, however, will depend on transparent implementation, timely back-series release, and sustained strengthening of India’s statistical ecosystem.
