What happened
The Ministry of Statistics and Programme Implementation released an updated edition of 'Sources and Methods for Compilation of National Accounts Statistics,' detailing how India computes its GDP and related macroeconomic aggregates. The document covers data sources, estimation methodologies, and sector-wise compilation approaches aligned with the System of National Accounts 2008 framework. It serves as the authoritative reference for understanding how CSO constructs India's national income estimates across agriculture, industry, and services sectors.

Why it matters
National Accounts Statistics (NAS) are the backbone of macroeconomic policymaking. India's GDP is compiled by the National Statistical Office (NSO), formerly the Central Statistics Office (CSO), under MoSPI. The compilation follows the System of National Accounts 2008 (SNA 2008), an internationally agreed standard maintained by the UN, IMF, World Bank, OECD, and Eurostat.
India measures GDP using three approaches: the Production (or Output) approach, the Expenditure approach, and the Income approach. In practice, India primarily uses the production approach at constant and current prices. The base year currently used is 2011-12, adopted in the 2015 revision that shifted from 2004-05.
Key data sources vary by sector. For agriculture, the document relies on Crop Production Statistics and area-yield data. For industry, it uses the Annual Survey of Industries (ASI), Index of Industrial Production (IIP), and MCA21 corporate database. For services, it draws on NSSO surveys, RBI data on financial services, and administrative records.
The document also explains the difference between Gross Value Added (GVA) and GDP: GDP = GVA + Taxes on products − Subsidies on products. GVA is compiled at basic prices; GDP is measured at market prices.
For aspirants, understanding these source distinctions matters because examiners test which agency provides data for which sector, and whether a given statistic is computed at constant prices (real) or current prices (nominal). The MCA21 database being used for non-financial corporations since the 2015 revision is a frequently tested modernisation detail.
