National Income

📘 AFCAT Economics · ECA01 ✈️ AFCAT Level : High Priority

National Income is the core AFCAT economics chapter. Questions are definitional — GDP vs GNP, per capita income, and basic poverty/unemployment concepts from NCERT. Keep answers direct and precise.

📌 AFCAT Pattern: GDP definition • GNP = GDP + NFIA • Per capita income formula • Poverty line concept • Unemployment meaning • India’s GDP rank globally

1. National Income Concepts

GDP (Gross Domestic Product): Total market value of all final goods and services produced within a country’s borders in one year, irrespective of who produces it.
GNP (Gross National Product) = GDP + NFIA. NFIA = Net Factor Income from Abroad. Income of Indian nationals globally (wherever produced).
NNP = GNP − Depreciation. Net National Product; after accounting for capital wear-and-tear.
National Income = NNP at Factor Cost.
Per Capita Income = National Income / Population. Average income per person. India’s per capita NI: ~Rs 1.72 lakh/year (FY24).
India’s GDP: ~USD 3.8 trillion (nominal); 5th largest globally; 3rd largest by PPP. Real GDP growth FY25: ~6.4%.

2. Poverty & Unemployment

Poverty Line: Minimum expenditure needed for basic necessities. People below = BPL (Below Poverty Line). Rangarajan Committee (2014): Rural Rs 972; Urban Rs 1,407 per month.
Absolute Poverty: Cannot afford basic needs. Relative Poverty: Income below national average proportion.
Disguised Unemployment: More workers than needed; zero marginal product. Common in Indian agriculture.
Unemployment Rate: Measured by PLFS (Periodic Labour Force Survey). India’s unemployment: ~7–8%.

📝 AFCAT PYQNational Income — AFCAT Pattern

Q1. GNP = GDP + what? (AFCAT I 2023)

(a) Depreciation (b) Net Factor Income from Abroad (c) Government transfers (d) Net indirect taxes

Answer: (b) Net Factor Income from Abroad (NFIA)
GNP covers production by Indian nationals anywhere in the world. GDP covers production within India’s territory regardless of nationality. NFIA = income Indians earn abroad minus income foreigners earn in India. NNP = GNP − Depreciation. AFCAT keeps this straightforward: GNP formula.

Q2. Per Capita Income is calculated as: (AFCAT II 2022)

(a) GDP × Population (b) National Income / Population (c) GNP / Workforce (d) Tax revenue / Households

Answer: (b) National Income / Population
Per Capita Income = National Income divided by total population. Used to compare living standards across nations. India has high total GDP but relatively lower per capita income due to large population (~1.4 billion).

📊 NI Chain

GNP = GDP + NFIA
NNP = GNP − Depreciation
NI = NNP at Factor Cost
Per Capita = NI / Population
India GDP: ~USD 3.8T; 5th largest (nominal)

🚫 AFCAT Traps

GDP = domestic (location); GNP = national (citizenship)
Per Capita = NI / Population (NOT GDP / Workforce)
Disguised unemployment = agriculture (NDA/AFCAT both test this)
