National income accounting measures economic activity through aggregates: GDP (production boundary), GVA (value added), NDP (net of depreciation), GNI (income from abroad). India uses 2011-12 base year, production and expenditure approaches. The shift from factor cost to market prices (2015), the GDP-GVA wedge (indirect taxes - subsidies), and quarterly estimates (NSO) are key. Real vs nominal, deflators, and sectoral composition (agriculture, industry, services) complete the framework.[TOPIC CLASSIFICATION]

[EXAMINER REASONING]
Trap: Confusing GDP at factor cost vs market prices. Since 2015, India reports GDP at market prices (GDP = GVA + indirect taxes - subsidies). Factor cost = market prices - net indirect taxes. Many aspirants use old factor cost terminology.
Most confused: GDP vs GVA vs NDP. GDP = GVA + net indirect taxes. NDP = GDP - consumption of fixed capital (depreciation). GNI = GDP + net primary income from abroad. The expenditure approach: GDP = C + I + G + (X-M). Many aspirants mix the identities.
Key anchor: Base year 2011-12 (since 2015). Sectoral shares (FY24): Agriculture ~18%, Industry ~26%, Services ~56%. Quarterly estimates (NSO, 6-7 weeks lag). Real (constant prices) vs nominal (current prices). GDP deflator = nominal GDP / real GDP * 100.
Current affairs hook: FY24 GDP growth 8.2% (real), GVA 7.2%. Nominal GDP ~Rs 295L cr. Per capita income ~Rs 1.86L. New base year (2022-23?) under discussion. The 'GDP back series' (2018) controversy. NSO's new surveys (ASUSE, PLFS) for informal sector.
Mains hinge: Assess: Does GDP capture welfare? The informal sector (90% employment, ~50% GVA), environmental degradation, inequality, and unpaid work are excluded. The 'green GDP' and 'beyond GDP' debates (HDI, SDGs, MPI) vs official statistics.
Core Concept
National income accounting in India follows UN System of National Accounts (SNA 2008). NSO (MoSPI) compiles estimates. Production approach: GVA = Output - Intermediate Consumption. GDP = GVA + Net Indirect Taxes (Indirect Taxes - Subsidies). NDP = GDP - Consumption of Fixed Capital (CFC, depreciation). GNI = GDP + Net Primary Income from Abroad. NNI = NDP + Net Primary Income from Abroad.
Expenditure approach: GDP = Private Final Consumption Expenditure (PFCE) + Government Final Consumption Expenditure (GFCE) + Gross Fixed Capital Formation (GFCF) + Change in Stocks + Valuables + Exports - Imports. FY24 shares: PFCE ~60%, GFCF ~30%, GFCE ~11%, Net Exports ~-1%.
Base year: 2011-12 (since Jan 2015). Sectoral (GVA, FY24): Agriculture & Allied ~18%, Industry (Mining, Manufacturing, Electricity, Construction) ~26%, Services ~56%. Quarterly estimates with ~6-7 week lag. Real GDP (constant 2011-12 prices) vs Nominal GDP (current prices). GDP deflator = Nominal/Real * 100.
Key debates: Back series (2018) revised pre-2011 data; informal sector measurement (ASUSE, PLFS); new base year (2022-23?) pending; environmental accounting (SEEA); GDP vs welfare (Sen, Stiglitz, Fitoussi Commission).
gva: Gross Value Added = Output - Intermediate Consumption
ndp: Net Domestic Product = GDP - Consumption of Fixed Capital (depreciation)
gni: Gross National Income = GDP + Net Primary Income from Abroad
nni: Net National Income = NDP + Net Primary Income from Abroad
expenditure: GDP = C + I + G + (X-M) = PFCE + GFCE + GFCF + ΔStocks + Valuables + X - M
base_year: 2011-12 (since Jan 2015)
sectoral_fy24: Agriculture ~18%, Industry ~26%, Services ~56% (GVA shares)
real_vs_nominal: Real = constant 2011-12 prices; Nominal = current prices
deflator: GDP Deflator = Nominal GDP / Real GDP * 100
quarterly: NSO estimates with ~6-7 week lag
fy24: Real GDP growth 8.2%, GVA 7.2%, Nominal GDP ~Rs 295L cr, Per capita ~Rs 1.86L

Statement Elimination Guide
Correct: GDP at market prices = GVA + Net Indirect Taxes (Taxes - Subsidies).
False: GDP and GVA are the same. (False. GDP = GVA + net indirect taxes.)
Trap: NDP = GDP - Net Indirect Taxes. (False. NDP = GDP - Depreciation/CFC.)
Correct: GNI = GDP + Net Primary Income from Abroad.
False: The base year for India's GDP is 2004-05. (False. 2011-12 since 2015.)
Trap: GDP includes depreciation. (True, GDP is gross; NDP is net of depreciation.)

Common Mistakes
Using factor cost terminology (replaced by market prices in 2015)
Confusing GDP, GVA, NDP, GNI (different boundaries: production, income, net of depreciation)
Thinking base year is still 2004-05 (2011-12 since 2015)
Mixing production and expenditure approach identities
Overlooking the GDP deflator as inflation measure for whole economy
Missing the informal sector (90% employment, ~50% GVA) measurement challenge
Not knowing the quarterly estimation lag (~6-7 weeks)
