- Basic concepts: factors of production, factor incomes, final vs intermediate goods.
- Circular flow: the loop of payments between households and firms.
- Three methods: product (value added), expenditure, and income.
- Aggregates chain: GDP MP to NDP, NNP, National Income, PI and PDI.

Topics in the National Income Accounting Chapter (Section Map)
The chapter is split into numbered sections. The table maps each one to the main exam idea you should pull from it.
| Section | NCERT sub-topic | Main exam concept |
|---|---|---|
| 2.1 | Basic concepts of macroeconomics | Factors of production, final vs intermediate goods |
| 2.2 | Circular flow and methods of calculation | Product, expenditure, income methods |
| 2.3 | Macroeconomic identities | The GDP MP to PDI aggregate chain |
| 2.4 | Nominal and real GDP | GDP deflator, CPI and WPI |
| 2.5 | GDP and welfare | Why GDP is an imperfect welfare measure |
Section 2.3 carries the most marks. The chain from GDP at Market Price down to Personal Disposable Income is the most tested topic in the whole book, so give it the most time.
Key Concepts in the National Income Accounting NCERT Chapter
These are the ideas the board paper rewards in textbook language. Try to write them in the exact NCERT phrasing.
- Four factors of production: land earns rent, labour earns wages, capital earns interest, and enterprise earns profit. Profit is the residual left after the other three are paid.
- Circular flow: households supply factors and get factor incomes; firms supply goods and get sales revenue. The flow runs both ways at once.
- Three methods agree: product, income and expenditure give the same GDP when there is no statistical discrepancy.
- Aggregate chain: GDP MP minus depreciation gives NDP MP; remove net indirect taxes for NDP FC; add net factor income from abroad for NNP FC, which is National Income.
- Savings-investment identity: (I minus S) + (G minus T) + (X minus M) = 0, the line that closes the chapter.

Ques. What is the chain of national income aggregates in this NCERT chapter?
Ans. GDP at MP minus depreciation gives NDP at MP. Remove net indirect taxes for NDP at FC. Add net factor income from abroad for NNP at FC, which is National Income. From there, adjust for taxes and transfers to reach Personal Income and Personal Disposable Income.

Ans. CBSE draws every theory question from the exact NCERT phrasing. Reference books rewrite the chapter and often drop the savings-investment identity and the GDP and welfare section, both of which are tested in the board paper.
Ques. How much weightage does Chapter 2 carry in the CBSE board paper?
Ans. About 5 to 6 marks across recent years. The common question is a five-mark numerical on GDP at Market Price by the expenditure method or National Income by the income method, plus short theory.
