GDP Measurement in India
NSO Methodology and Base Year
India's Gross Domestic Product (GDP) is compiled and published by the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI). GDP is measured using the expenditure approach (summing consumption, investment, government spending, and net exports) and cross-checked using the production/value-added approach via Gross Value Added (GVA). India's GDP data is released as: (1) First Advance Estimate (January), (2) Second Advance Estimate (February), (3) First Revised Estimate, and (4) Final Estimate. A new GDP series with base year 2022-23 was introduced in 2026, replacing the earlier 2011-12 base year series.
