National Income Accounting

What is GDP in one line?

Gross Domestic Product (GDP) is the value of all final goods and services made within a country’s borders in a year.

Can we see it with a tiny example?

Imagine a country that makes only two things in a year.

• Rice worth ₹500 crore.
• Phones worth ₹2,000 crore.
• Its GDP is the total: ₹2,500 crore.

Why count only final goods?

The screen inside a phone is already part of the phone’s price. If we counted the screen and the phone, we would count the screen twice. This mistake is called double counting. So only the final product counts.

What is GNP?

Gross National Product (GNP) looks at what a country’s people earn, wherever they are. So it is GDP plus the net income from abroad. That is income Indians earn abroad, minus income foreigners earn in India.

What is NNP?

Net National Product (NNP) = GNP − depreciation.

• A factory’s machines wear out a little every year.
• Say GNP is ₹100 crore, and machines lose ₹5 crore of value.
• Then NNP is ₹95 crore.
• NNP is the more honest number. It is what the economy really gained after the wear and tear.

What is per capita income?

Per capita income is national income divided by the total population. Say national income is ₹200 lakh crore and there are 140 crore people. Per capita income is then about ₹1.43 lakh per person per year.

Here’s the catch. It is only an average. Some people earn far more, and many earn far less.

How does each method see the same bakery?

• Production method: counts the value of all the bread the bakery makes.
• Income method: adds up what the bakery pays out, as wages to workers and profit to the owner.
• Expenditure method: counts what customers spend buying that bread.

In theory, all three give the same total. They are just three angles on one flow of money. One person’s spending is another person’s income.

What is the difference?

• Nominal GDP uses today’s prices (current prices).
• Real GDP uses fixed prices from a base year (constant prices). So it takes inflation out.

Why does that matter?

Say output value rises from ₹100 crore to ₹110 crore. That looks like 10% growth. But if prices also rose 6%, most of that “growth” is just things costing more. Real growth is only about 4%. Real GDP shows how much more stuff was actually made.

And what about PPP-GDP?

Nominal GDP in dollars uses the market exchange rate. PPP-GDP instead adjusts for local prices, using the same basket of goods in each country. Things are cheaper in India, so India looks bigger in PPP terms.

• By PPP-GDP, India is third in the world, after China and the US.
• By nominal GDP, India was sixth in the IMF’s April 2026 outlook. A weaker rupee was a big reason. (Source: Deccan Herald)

Who made the first estimates?

• Dadabhai Naoroji made the first attempt, for 1867-68. He put per capita income at about ₹20 a year. He used rough estimates, not proper data.
• Dr V.K.R.V. Rao made the first scientific estimate, in 1931, with proper statistical methods.
• In 1949, independent India set up the National Income Committee. P.C. Mahalanobis headed it. D.R. Gadgil and V.K.R.V. Rao were members.

Who does it today?

The National Statistical Office (NSO) prepares India’s official income numbers. It works under the Ministry of Statistics and Programme Implementation (MoSPI). It was formed in 2019 by merging two older bodies, the Central Statistics Office and the National Sample Survey Office. One body now means one consistent set of numbers.

What are the main sectors?

• Primary: takes things straight from nature. Farming, dairy, fishing, mining and mineral exploration.
• Secondary: turns raw material into a finished product. Weaving cloth, manufacturing, construction.
• Tertiary: gives a service, not a good. Storage, transport, banking, trade.
• Quaternary: knowledge-based services, like IT, research and consulting. Some books treat it as part of the tertiary sector.

Follow a cotton shirt. Growing cotton is primary. Weaving and stitching are secondary. The shop that sells it is tertiary.

Why is storage a tertiary activity?

Storing crops looks like farming work. But storage does not change the crop. It only holds it until someone needs it. So it is a service, like transport. This is a favourite exam trap.

What is fixed capital versus working capital?

• Fixed capital lasts through many rounds of work. A computer, or a farmer’s plough.
• Working capital is used up in one round. Petrol, or yarn that becomes cloth.
• Simple test: is it used up once, or used again and again?

What does GDP leave out?

• Unpaid work: a parent caring for children at home is not counted.
• Damage to nature: a factory’s output counts, but the river it pollutes does not count against it.
• Inequality: a rising average can hide that most gains went to a few people.

So a country’s GDP can rise while its air, rivers and many people’s lives get worse. GDP measures growth. It does not fully measure development.

How fast did the economy grow?

• Real GDP grew 7.8% in Q1 (April–June) of FY2026-27.
• That was up from 6.9% in the same quarter a year earlier.
• It beat the RBI’s earlier forecast of 7%.
• Nominal GDP grew faster, at 10.3%. The gap is mostly price rise.
• These numbers use the new GDP series, with 2022-23 as the base year.

Why did a rating agency take notice?

• On 2 September 2026, the Japan Credit Rating Agency (JCR) raised India’s long-term rating from BBB+ to A-.
• It pointed to India’s steady growth of around 7%.
• It is India’s first A-category rating from an international agency in over 35 years.
