India's GDP is compiled by the National Statistics Office under MoSPI, which on 27 February 2026 moved the national accounts base year from 2011-12 to 2022-23, adding double deflation, Supply and Use Tables and new data such as GST and annual household surveys. On 15 October 2026, an IMF director called the revision consistent with IMF advice.

Syllabus: GS3 · Indian Economy & Growth; Prelims · Economy & Social Development

Why this matters for UPSC

GS3 Indian economy: growth and its measurement. Prelims can ask GDP versus GVA, double deflation, the base year and who compiles national accounts; GS3 Mains, how data quality shapes policy and trust.

In short

GDP measures the value of goods and services an economy produces in a year; MoSPI's National Statistics Office compiles it against a base year, now 2022-23 instead of 2011-12.

The 2022-23 series makes India's GDP more granular and timely; its credibility now rests on a prompt back series and transparent documentation.

Why it matters

Farmers, small traders, lenders and State governments all live with decisions built on GDP numbers: which crops get support, where industrial policy aims, how much credit a firm can raise. When informal enterprises are estimated by stretching surveys from the base year, their real contribution is guessed rather than measured. Yearly surveys, item-level price indices and a product-by-product balance of supply and use bring the numbers closer to what is actually happening, and a smaller gap between production and spending estimates leaves less room for doubt. Credible statistics matter abroad as well: investors and international lenders read them, and a disputed series costs the country trust.

Prelims pointers

  • GDP growth and GVA growth can differ because GDP adds taxes on products and subtracts subsidies on products from total GVA.
  • Gross State Domestic Product is compiled by each State's or UT's Directorate of Economics and Statistics, following NSO guidelines.
  • India subscribes to the IMF's Special Data Dissemination Standard (SDDS).
  • Quarterly GDP estimates follow SNA 2008 and the IMF's Quarterly National Accounts Manual, 2017.
  • Financial-sector estimates use data from regulators such as RBI and SEBI; private corporate estimates use company filings in MCA-21.
  • Wages of hired domestic workers, treated as households employing domestic personnel, are counted in GDP using PLFS data.
  • Government output, not sold in markets, is valued at cost: compensation of employees, intermediate consumption and consumption of fixed capital.
  • SNA 2008 lets a statistical discrepancy be published openly or reconciled through Supply and Use Tables.

Practise a UPSC-style question

With reference to the measurement of national income in India, consider the following statements:

1. Gross Value Added is the value of output after deducting the cost of raw materials and other inputs used to produce it.

2. GDP is obtained by adding taxes on products to total Gross Value Added and subtracting subsidies on products.

Which of the statements given above is/are correct?

  1. (a) 1 only
  2. (b) 2 only
  3. (c) Both 1 and 2
  4. (d) Neither 1 nor 2
Show the answer

Answer: (c) Both 1 and 2

Answer: (c) Both 1 and 2. GVA nets out inputs, and GDP adds net taxes on products to it.

Statement 1: correct. MoSPI defines GVA as the value of goods and services produced minus the cost of raw materials and inputs used to produce them.

Statement 2: correct. GDP is the sum of all GVAs plus taxes on products less subsidies on products, together called net taxes on products.

Eliminate: Statement 1 is the standard definition of value added, so it is correct. Out: (b), (d).

Eliminate: Statement 2 gives the standard bridge from GVA to GDP, so it is correct. Out: (a).

Trap: Reversed direction. A student who mixes up the bridge may think subsidies are added and taxes removed, and so reject a correct statement 2.

Remember: GDP = total GVA + taxes on products - subsidies on products.
