 New GDP Series with 2022-23 Base Year Introduces Five Further Changes in India’s National Income Measurement

Recent Developments:

• The Ministry of Statistics and Programme Implementation (MoSPI) released the new series of Annual and Quarterly National Accounts Estimates with 2022-23 as the base year on 27 February 2026, replacing the earlier 2011-12 series. The revision aims to capture structural changes, incorporate newer data sources, improve estimation methods and strengthen the coverage and accuracy of national accounts.
• MoSPI subsequently released “Sources and Methods for Compilation of National Accounts Statistics” on 21 September 2026, providing a consolidated account of the concepts, data sources, classifications and methodologies used in the new series. The series remains based on 2022-23 despite subsequent incorporation of updated price and industrial indicators.
• The revision is broader than base-year rebasing and includes methodological improvements such as better deflation, wider use of administrative data, improved informal-sector measurement and more granular sectoral estimation.

Five Additional Methodological Changes:

1. Activity-Based Classification of Manufacturing and Services:

• Under the 2011-12 series, enterprises engaged in multiple activities were generally classified according to their principal or major activity, with their GVA largely assigned to the sector contributing the largest share of turnover.
• Under the 2022-23 series, GVA of a multi-activity enterprise is distributed between manufacturing and services according to the respective activity shares, providing a more granular representation of sectoral production.
• MoSPI uses activity-wise information from MGT-7 and MGT-7A forms filed with the Ministry of Corporate Affairs, where business activities contributing at least 10% of turnover are reported with their respective shares.
• This change is important because large enterprises increasingly operate across manufacturing and service activities, making single-sector classification less representative of their actual economic contribution.

2. Inclusion of Government-Provided Housing Services:

• Government employees receiving official accommodation obtain a housing service even though they may not receive an equivalent House Rent Allowance for that accommodation.
• Under the earlier methodology, the imputed value of this housing service was not separately captured in the same manner, creating a coverage gap in measuring government-provided services.
• The new methodology values such housing services using the cost of construction, after accounting for repairs, maintenance and annual consumption of fixed capital.
• The change illustrates the national accounting principle that non-market services can also have an economic value and may need to be imputed when no market transaction directly records their value.

3. Revision of Useful Life of Fixed Assets:

• The new GDP series revises the estimated average useful life of several fixed assets for calculating consumption of fixed capital, commonly referred to as depreciation.
• For dwellings, the assumed average useful life has been revised to 60-75 years, compared with 70-80 years under the earlier series.
• MoSPI periodically reviews asset lives by considering technological change, obsolescence, operating conditions, maintenance practices and regulatory requirements.
• A revised useful life changes the annual consumption of fixed capital and therefore affects the measurement of GVA and other national accounts aggregates.

4. Improved Measurement of Household Savings:

• Household savings in national accounts include savings through financial assets, physical assets and valuables, including gold and silver ornaments.
• For financial savings, the new series uses data from SEBI for instruments such as shares, debentures, hybrid instruments and mutual funds, replacing the earlier reliance on RBI-based data for these components.
• The broader SEBI-based coverage facilitates the inclusion of newer investment instruments such as REITs, InvITs and Alternative Investment Funds (AIFs).
• The estimated nominal household savings in gold and silver ornaments for 2022-23 increased to ₹1.65 lakh crore, compared with ₹64,504 crore in the previous series.
• These estimates continue to rely on the 2019 All India Debt and Investment Survey (AIDIS), while MoSPI initiated a fresh AIDIS in July 2026, scheduled for completion in June 2027.

5. Inclusion of Household Rooftop Solar Electricity:

• The new series includes electricity generated by households through rooftop solar systems for self-consumption, thereby expanding the measured production boundary of the economy.
• For 2022-23 and 2023-24, estimates are based on the respective Household Consumption Expenditure Surveys and population projections from the Ministry of Health.
• From 2024-25 onwards, estimation uses growth in installed rooftop solar capacity reported by the Ministry of New and Renewable Energy (MNRE) along with the applicable per-unit electricity price.
• The estimated output is included under the electricity, gas, water supply and other utility services sector.
• The change improves measurement of decentralised renewable-energy production because electricity generated and consumed within households may not appear in conventional electricity-sales data.

Wider Methodological Improvements in the 2022-23 Series:

Better Measurement of Real Economic Growth:

• The new series moves towards more granular deflation techniques, including double deflation for most manufacturing categories, instead of relying predominantly on a single broad deflator.
• As of the latest methodology information, 28 of 30 manufacturing categories use double deflation, while work continues for the remaining two categories.
• Double deflation separately adjusts output and intermediate consumption for price changes, allowing real GVA to better reflect changes in physical economic activity.

New Data Sources and Administrative Databases:

• The revised national accounts make wider use of GST data, PFMS, e-Vahan, household surveys and other administrative datasets, reducing dependence on proxy indicators and improving sectoral estimation.
• The household sector is also estimated using more recent survey information, including the Annual Survey of Unincorporated Sector Enterprises (ASUSE) and Periodic Labour Force Survey-related information.
• The new framework also incorporates Supply and Use Tables (SUTs) to strengthen consistency between production, consumption and expenditure estimates. MoSPI released the first SUTs under the 2022-23 base year in May 2026.

Significance for Indian Economy and Policy:

More Representative National Accounts:

• The revised methodology captures economic activities that were previously under-measured or classified less precisely, including multi-activity enterprises, government housing services and self-consumed rooftop electricity.
• Greater use of administrative and survey data improves the granularity, timeliness and sectoral coverage of national income estimation.
• The revised asset lives and improved price-adjustment methods can alter measured GVA, depreciation and real growth without implying an equivalent change in the underlying physical economy.
• Better measurement of household financial assets is increasingly important because Indian households now use a wider range of market-linked financial instruments.

Implications for States and Regional Accounts:

• The base-year revision also requires States and Union Territories to update their GSDP and regional accounts to maintain consistency and comparability with national-level estimates. MoSPI issued uniform guidelines for Gross State Value Added (GSVA) estimates with the 2022-23 base year in May 2026.

UPSC Prelims and Mains Relevance:

Value Addition for UPSC:

Conceptual Linkages:

• GDP → GVA: GVA measures value added by producers, while GDP at market prices additionally incorporates net taxes on products.
• Base Year → Real GDP: The base year provides the reference-price structure used for calculating constant-price estimates and real economic growth.
• Double Deflation → Real GVA: Output and intermediate consumption are separately adjusted for price changes, improving measurement of real value added.
• Consumption of Fixed Capital → GVA: Revised asset lives affect depreciation estimates and consequently influence national accounts aggregates.
• Imputation → Non-Market Production: Government-provided housing and self-consumed rooftop solar demonstrate how national accounts assign economic values to production without conventional market transactions.
• Administrative Data → Statistical Modernisation: GST, MCA filings, SEBI information, PFMS and e-Vahan illustrate the growing role of administrative datasets in official statistics.
• UPSC GS-III Link: The topic connects national income accounting, economic growth, statistical reforms, renewable energy, financialisation of household savings and evidence-based policymaking.
• Mains Angle: A strong answer can argue that GDP rebasing is not merely a statistical exercise; it is a periodic attempt to align the measurement framework with structural transformation, technological change, emerging economic activities and improved data availability.
