Gross Domestic Product (GDP)
/ɡrəʊs dəˈmɛstɪk ˈprɒdʌkt/The total monetary value of all final goods and services produced within the domestic territory of a country during a specified period (usually a financial year), regardless of whether the producers are citizens or foreigners. GDP can be calculated by three methods: (1) Production/Value Added method — sum of GVA across all sectors; (2) Income method — sum of all factor incomes (wages, rent, interest, profit); (3) Expenditure method — C + I + G + (X − M), where C = private consumption, I = investment, G = government spending, X = exports, M = imports. India's GDP is compiled by the NSO with base year 2011-12, aligned with SNA 2008. The headline GDP is reported at market prices, while GVA at basic prices is used for sector-wise analysis.
Context & Background
India became the 5th largest economy by nominal GDP (overtaking the UK in 2022) and is the 3rd largest by PPP. The 2011-12 base year revision (announced January 2015) introduced GVA at basic prices, used MCA21 corporate filings data, and aligned with international SNA 2008 standards. The revision was controversial — backcast GDP growth rates were higher under the new series, with some economists questioning the methodology. Nominal vs. real GDP distinction is critical — real GDP (constant prices) removes inflation effects and is used for growth rate calculations. The GDP Deflator (Nominal GDP / Real GDP × 100) is an implicit price index covering all goods and services, unlike CPI (consumer basket) or WPI (wholesale goods only).
UPSC Exam Relevance
GS3 Economy — Prelims: GDP = production within domestic territory, GNP = GDP + NFIA, base year 2011-12, three methods of calculation, nominal vs real, GDP Deflator; Mains: Is GDP an adequate measure of welfare? (ignores inequality, environment, unpaid work), base year revision debate, GVA at basic prices vs GDP at market prices, India's GDP ranking (5th nominal, 3rd PPP), data reliability concerns, GDP growth vs inclusive growth.
