Why in the News?
Recently, the CEO of NITI Aayog announced that India has moved ahead of Japan to become the world’s fourth-largest economy.
What is the key difference between nominal GDP and PPP-based GDP?
- Nominal GDP: Measured using current market exchange rates in US dollars. Eg: If India’s GDP is ₹270 lakh crore and $1 = ₹75, then nominal GDP = ₹270 lakh crore ÷ 75 = $3.6 trillion.
- PPP-Based GDP: Adjusted for differences in the cost of living and price levels between countries. Eg: If goods and services are cheaper in India, PPP adjusts the GDP upward to reflect greater actual consumption — India’s GDP could be $12 trillion in PPP terms, even though nominal GDP is lower.
When did India become the third-largest economy by PPP estimates?In 2009, India overtook Japan in PPP-based GDP. This milestone occurred during the tenure of the Manmohan Singh-led UPA government. India has retained the 3rd position ever since, behind only China and the United States. The PPP-based ranking reflects India’s large population and lower cost of living, which boosts its effective domestic consumption. |
How do exchange rates affect nominal GDP rankings?
- Conversion Dependency: Nominal GDP is calculated in US dollars, so a country’s GDP in local currency must be converted using the exchange rate. Eg: If India’s GDP is ₹300 lakh crore and $1 = ₹75, its dollar GDP would be $4 trillion; but if $1 = ₹85, the same GDP becomes $3.5 trillion.
- Exchange Rate Fluctuations Can Distort Rankings: A country’s global GDP rank can change without any real economic growth or decline, simply due to currency appreciation or depreciation. Eg: If the Japanese yen strengthens against the dollar, Japan’s nominal GDP in dollars rises—even if its actual output hasn’t changed.
- Unfair Comparison Across Countries: Countries with volatile or weakening currencies may appear smaller in nominal terms than they are in real domestic terms. Eg: India’s GDP may seem lower than the UK’s in nominal terms due to a weaker rupee, even if India produces more goods and services overall.
Why is per capita GDP more reflective of individual prosperity?
- Accounts for Population Size: Per capita GDP divides total GDP by the population, showing the average income per person, unlike aggregate GDP which may hide disparities. Eg: India’s GDP is higher than the UK’s in total, but because India has over 20 times the population, its per capita GDP is much lower.
- Better Indicator of Living Standards: It reflects the average economic well-being and purchasing power of citizens, making it more relevant for assessing prosperity. Eg: A country with $50,000 per capita GDP (like the UK) offers far better public services, infrastructure, and living conditions than one with $2,800 (like India), even if total GDPs are comparable.
- Highlights Income Distribution and Development Needs: Low per capita GDP suggests widespread poverty or unequal wealth distribution, even if overall GDP is growing. Eg: Despite being the world’s 5th largest economy, India’s low per capita GDP shows most individuals have limited incomes and access to economic benefits.
What does India’s per capita GDP reveal compared to the UK’s?
| Aspect | India | UK | Example |
| Per Capita GDP (2025) | 10,020 PPP dollars | 58,140 PPP dollars | UK’s per capita income is ~6 times higher than India’s. |
| Living Standards & Services | Lower access to quality services | Higher standard of living, social welfare | Indians have limited access to healthcare, education, and housing |
| Economic Inequality & Prosperity | Aggregate GDP is growing, but benefits are not evenly distributed | Prosperity is more widely shared | Despite India’s growth, individual prosperity remains low on average. |
Way forward:
- Invest in Human Capital and Social Infrastructure: India must enhance spending on education, healthcare, and skill development to improve productivity and raise per capita incomes. Improved human capital directly boosts innovation, employability, and long-term economic growth.
- Focus on Inclusive and Equitable Growth: Policies should ensure that economic gains are widely distributed, especially through rural development, MSME support, and targeted welfare schemes. This will reduce income disparities and lift more people into the formal, productive economy, improving per capita prosperity.
Mains PYQ:
[UPSC 2022] Is inclusive growth possible under market economy? State the significance of financial inclusion in achieving economic growth in India.
Linkage: India’s high aggregate economic rank alongside low per capita income, raises questions about how India’s economic growth model is translating into shared prosperity, a central theme of inclusive growth. This question explicitly asks about the possibility and mechanisms (like financial inclusion) of achieving “inclusive growth” within a market economy.
