National Income Accounting and Related Concepts – ICSI CSEET (Paper-3)

National Income Accounting and Related Concepts – ICSI CSEET (Paper-3)


National income is an uncertain term which is used interchangeably with national dividend, national output and national expenditure. On this basis, national income has been defined in a number of ways. In common parlance, national income means the total value of goods and services produced annually in a country.

In other words, the total amount of income accruing to a country from economic activities in a year’s time is known as national income. It includes payments made to all resources in the form of wages, interest, rent and profits.

National Income or Net National Income is Gross National Income or Gross National Product less depreciation. It is to be noted that National Income includes Net Factor Income Earned from Abroad also. While computing National Income only finished or final goods are considered as factoring intermediate goods used for manufacturing would amount to double counting. It includes taxes but does not include subsidies.



There are three methods of measuring national income of a country. They yield the same result. These methods are:

1)    The Product Method or Value Added Method.

(2)   The Income Method.

(3)   The Expenditure Method

(1)   The Product Method : The Product method measures the contribution of each producing enterprise in the domestic territory of the country. This method involves the following steps:

(a)   Identifying the producing enterprise and classifying them into individual sectors according to their activities.

(b)   Estimating net value added by each producing enterprise as well as each industrial sector and adding up the net value added by all the sectors.

Goods and services are counted in gross domestic product (GDP) at their market values. The product approach defines a nation’s gross product as that market value of goods and services currently produced within a nation during a one year period of time.

The product approach measuring national income involves adding up the value of all the final goods and services produced in the country during the year. Here we focus on various sectors of the economy and add up all their production during the year. The main sectors whose production value is added up are:

(i)    agriculture (ii) manufacturing (iii) construction (iv) transport and communication (v) banking (vi) administration and defence and (vii) distribution of income.

Precautions for Product Method or Value Added Method

(i)    Problem of double counting : When we add up the value of output of various sectors, we should be careful to avoid double counting. This pitfall can be avoided by either counting (he final value of the output or by including the extra value that each firm adds to an item.

(ii)        Value addition in particular year : While calculating national income, the values of goods added in the particular year in question are added up. The values which had previously

been added to the stocks of raw material and goods have to be ignored. GDP thus includes only those goods, and services that are newly produced within the current period.

(iii)   Stock appreciation : Stock appreciation, if any, must be deducted from value added. This is necessary as there is no real increase in output.

(iv)  Production for self consumption : The production of goods for self consumption should be counted while measuring national income. In this method, the production of goods for self consumption should be valued at the prevailing market prices.

(2)   Expenditure Method : The expenditure approach measures national income as total spending on final goods and services produced within nation during a year. The expenditure approach to measuring national income is to add up all expenditures made for final goods and services at current market prices by households, firms and government during a year. Total aggregate final expenditure on final output thus is the sum of four broad categories of expenditures:

(i)    Consumption (ii) Investment (iii) Government and (iv) Net export.

(i)    Consumption expenditure (C) : Consumption expenditure is the largest component of national income. It includes expenditure on all goods and services produced and sold to the final consumer during the year.

(ii)   Investment expenditure (I) : Investment is the use of today’s resources to expand tomorrow’s production or consumption. Investment expenditure is expenditure incurred on by business firms on (a) new plants, (b) adding to the stock of inventories and (c) on newly constructed houses.

(iii)   Government expenditure (G) : It is the second largest component of national income. It includes all government expenditure on currently produced goods and services but excludes transfer payments while computing national income.

(iv)  Net exports (X – M) : Net exports are defined as total exports minus total imports. National income calculated from the expenditure side is the sum of final consumption expenditure, expenditure by business on plants, government spending and net exports.

Precautions for Expenditure Method

(i)    The expenditure on second hand goods should not be included as they do not contribute to the current year’s production of goods.

(ii)   Similarly, expenditure on purchase of old shares and bonds is not included as these also do not represent expenditure on currently produced goods and services.

(iii)   Expenditure on transfer payments by government such as unemployment benefit, old age pensions, interest on public debt should also not be included because no productive service is rendered in exchange by recipients of these payments.

(3)   Income Method : Income approach is another alternative way of computing national income, This method seeks to measure national income at the phase of distribution. In the production process of an economy, the factors of production are engaged by the enterprises. They are paid money incomes for their participation in the production. The payments received by the factors and paid by the enterprises are wages, rent, interest and profit. National income thus may be defined as the sum of wages, rent, interest and profit received or occurred to the factors of production in lieu of their services in the production of goods. Briefly, national income is the sum of all income, wages, rents, interest and profit paid to the four factors of production. The four categories of payments are briefly described below:

(i)    Wages : It is the largest component of national income. It consists of wages and salaries along with fringe benefits and unemployment insurance.

(ii)   Rents : Rents are the income from properly received by households.

(iii)   Interest : Interest is the income private businesses pay to households who have lent the business money.

(iv)  Profits: Profits are normally divided into two categories (a) profits of incorporated businesses and (b) profits of unincorporated businesses (sole proprietorship, partnerships and producers cooperatives).

Precautions for Income Method

While estimating national income through income method, the following precautions should be undertaken.

(i)    Transfer payments such as gifts, donations, scholarships, indirect taxes should not be included in the estimation of national income.

(ii)   Illegal money earned through smuggling and gambling should not be included.

(iii)   Windfall gains such as prizes won, lotteries etc. is not be included in the estimation of national income.

(iv)  Receipts from the sale of financial assets such as shares, bonds should not be included in measuring national income as they are not related to generation of income in the current year production of goods.


Gross Domestic Product (GDP)

GDP is the total value of goods and services produced within the country during a year. This is calculated at market prices and is known as GDP at market prices. Dernberg defines GDP at market price as “the market value of the output of final goods and services produced in the domestic territory of a country during an accounting year.”

There are three different ways to measure GDP:

Methods of Measure GDP
The Product Method
The Income Method
Expenditure Method

(a)   The Product Method : In this method, the value of all goods and services produced in different industries during the year is added up. This is also known as the value added method to GDP or GDP at factor cost by industry of origin. The following items are included in India in this: agriculture and allied services; mining; manufacturing, construction, electricity, gas and water supply; transport, communication and trade; banking and insurance, real estates and ownership of dwellings and business services; and public administration and defence and other services (or government services). In other words, it is the sum of gross value added.

(b)   The Income Method : The people of a country who produce GDP during a year receive incomes from their work. Thus GDP by income method is the sum of all factor incomes: Wages and Salaries (compensation of employees) + Rent + Interest + Profit.

(c)   Expenditure Method : This method focuses on goods and services produced within the country during one year. GDP by expenditure method includes:

  1. Consumer expenditure on services and durable and non-durable goods (C).
  2. Investment in fixed capital such as residential and non-residential building, machinery, and inventories (I).
  3. Government expenditure on final goods and services (G).
  4. Export of goods and services produced by the people of country (X).
  5. Less imports (M). That part of consumption, investment and government expenditure which is spent on imports is subtracted from GDP. Similarly, any imported component, such as raw materials, which is used in the manufacture of export goods, is also excluded.

Thus GDP by expenditure method at market prices = C+ I + G + (X – M), where (X-M) is net export which can be positive or negative.

GDP at Factor Cost

GDP at factor cost is the sum of net value added by all producers within the country. Since the net value added gets distributed as income to the owners of factors of production, GDP is the sum of domestic factor incomes and fixed capital consumption (or depreciation).

Thus GDP at Factor Cost = Net value added + Depreciation.

GDP at factor cost includes:

(a)   Compensation of employees i.e., wages, salaries, etc.

(b)   Operating surplus which is the business profit of both incorporated and unincorporated firms

[Operating Surplus = Gross Value Added at Factor Cost—Compensation of Employees— Depreciation].

(c)   Mixed Income of Self- employed.

Conceptually, GDP at factor cost and GDP at market price must be identical/This is because the factor cost (payments to factors) of producing goods must equal the final value of goods and services at market prices. However, the market value of goods and services is different from the earnings of the factors of production.

In GDP at market price indirect taxes are included and subsidies by the government are excluded. Therefore, in order to arrive at GDP at factor cost, indirect taxes are subtracted and subsidies are added to GDP at market price.

Thus, GDP at Factor Cost = GDP at Market Price – Indirect Taxes + Subsidies.

(i)    Net Domestic Product (NDP) : NDP is the value of net output of the economy during the year. Some of the country’s capital equipment wears out or becomes obsolete each year during the production process. The value of this capital consumption is some percentage of gross investment which is deducted from GDP. Thus Net Domestic Product = GDP at Factor Cost – Depreciation.

(ii)   Nominal and Real GDP : When GDP is measured on the basis of current price, it is called GDP at current prices or nominal GDP. On the other hand, when GDP is calculated on the basis of fixed prices in some year, it is called GDP at constant prices or real GDP.

Nominal GDP is the value of goods and services produced in a year and measured in terms of rupees (money) at current (market) prices. In comparing one year with another, we are faced with the problem that the rupee is not a stable measure of purchasing power. GDP may rise a great deal in a year, not because the economy has been growing rapidly but because of rise in prices (or inflation).

On the contrary, GDP may increase as a result of fall in prices in a year but actually it may be less as compared to the last year. In both 5 cases, GDP does not show the real state of the economy. To rectify the underestimation and overestimation of GDP, we need a measure that adjusts for rising and falling prices.

This can be done by measuring GDP at constant prices which is called real GDP. To find out the real GDP, a base year is chosen when the general price level is normal, i.e., it is neither too high nor too low. The prices are set to 100 (or 1) in the base year.

Now the general price level of the year for which real GDP is to be calculated is related to the base year on the basis of the following formula which is called the deflator index:

Real GDP = GDP for the Current Year x Base Year (100) / Current Year Index

GDP Deflator

GDP deflator is an index of price changes of goods and services included in GDP. It is a price index which is calculated by dividing the nominal GDP in a given year by the real GDP for the same year and multiplying it by 100. Thus,

GDP Deflator = Nominal (or Current Price) GDP/Real(or Constant  Price) GDP* 100

Gross National Product (GNP)

GNP is the total measure of the flow of goods and services at market value resulting from current production during a year in a country, including net income from abroad.

GNP includes four types of final goods and services:

  1. Consumers’ goods and services to satisfy the immediate wants of the people;
  2. Gross private domestic investment in capital goods consisting of fixed capital formation, residential construction and inventories of finished and unfinished goods;
  3. Goods and services produced by the government; and
  4. Net exports of goods and services, i.e., the difference between value of exports and imports of goods and services, known as net income from abroad.

In this concept of GNP, there are certain factors that have to be taken into consideration:

First, GNP is the measure of money, in which all kinds of goods and services produced in a country during one year are measured in terms of money at current prices and then added together.

Second, in estimating GNP of the economy, the market price of only the final products should be taken into account. Many of the products pass through a number of stages before they are ultimately purchased by consumers.

If those products were counted at every stage, they would be included many a time in the national product. Consequently, the GNP would increase too much. To avoid double counting, therefore, only the final products and not the intermediary goods should be taken into account.

Third, goods and services rendered free of charge are not included in the GNP, because it is not possible to have a correct estimate of their market price. For example, the bringing up of a child by the mother, imparting instructions to his son by a teacher, recitals to his friends by a musician, etc.

Fourth, the transactions which do not arise from the produce of current year or which do not contribute in any way to production are not included in the GNP. The sale and purchase of old goods, and of shares, bonds and assets of existing companies are not included in GNP because these do not make any addition to the national product, and the goods are simply transferred.

Fifth, the payments received under social security, e.g., unemployment insurance allowance, old age pension, and interest on public loans are also not included in GNP, because the recipients do not provide any service in lieu of them. But the depreciation of machines, plants and other capital goods is not deducted from GNP.

Sixth, the profits earned or losses incurred on account of changes in capital assets as a result of fluctuations in market prices are not included in the GNP if they are not responsible for current production or economic activity.

For example, if the price of a house or a piece of land increases due to inflation, the profit earned by selling it will not be a part of GNP. But if, during the current year, a portion of a house is constructed anew, the increase in the value of the house (after subtracting the cost of the newly constructed portion) will be included in the GNP. Similarly, variations in the value of assets, that can be ascertained beforehand and are insured against flood or fire, are not included in the GNP.

Last, the income earned through illegal activities is not included in the GNP. Although the goods sold in the black market are priced and fulfil the needs of the people, but as they are not useful from the social point of view, the income received from their sale and purchase is always excluded from the GNP.

There are two main reasons for this. One, it is not known whether these things were produced during the current year or the preceding years. Two, many of these goods are foreign made and smuggled and hence not included in the GNP.

Three Approaches to GNP

After having discussed the basic constituents of GNP, it is essential to know how it is estimated. Three approaches are employed for this purpose. One, the income method to GNP; two, the expenditure method to GNP and three, the value added method to GNP. Since gross income equals gross expenditure, GNP estimated by all these methods would be the same with appropriate adjustments.

  1. Income Method to GNP : The income method to GNP consists of the remuneration paid in terms of money to the factors of production annually in a country.

Thus GNP is the sum total of the following items:

(a)   Wages and salaries : Under this head are included all forms of wages and salaries earned through productive activities by workers and entrepreneurs. It includes all sums received or deposited during a year by way of all types of contributions like overtime, commission, provident fund, insurance, etc.

(b)   Rents : Total rent includes the rents of land, shop, house, factory, etc. and the estimated rents of all such assets as are used by the owners themselves.

(c)   Interest : Under interest comes the income by way of interest received by the individual of a country from different sources. To this is added, the estimated interest on that private capital which is invested and not borrowed by the businessman in his personal business. But the interest received on governmental loans has to be excluded, because it is a mere transfer of national income.

(d)   Dividends : Dividends earned by the shareholders from companies are included in the GNP.

(e)   Undistributed corporate profits : Profits which are not distributed by companies and are retained by them are included in the GNP.

(f)    Mixed incomes : These include profits of unincorporated business, self-employed persons and partnerships. They form part of GNP.

(g)   Direct taxes : Taxes levied on individuals, corporations and other businesses are included in the GNP.

(h)   Indirect taxes : The government levies a number of indirect taxes, like excise duties and sales tax. These taxes are included in the price of commodities. But revenue from these goes to the government treasury and not to the factors of production. Therefore, the income due to such taxes is added to the GNP.

(i)    Depreciation : Every corporation makes allowance for expenditure on wearing out and depreciation of machines, plants and other capital equipment. Since this sum also is not a part of the income received by the factors of production, it is, therefore, also included in the GNP.

(j)    Net income earned from abroad : This is the difference between the value of exports of goods and services and the value of imports of goods and services. If this difference is positive, it is added to the GNP and if it is negative, it is deducted from the GNP.

GNP according to the Income Method = Wages and Salaries + Rents + Interest + Dividends + Undistributed Corporate Profits + Mixed Income + Direct Taxes + Indirect Taxes + Depreciation + Net Income from abroad.

  1. Expenditure Method to GNP : From the expenditure view point, GNP is the sum total of expenditure incurred on goods and services during one year in a country.

It includes the following items:

(a)   Private consumption expenditure : It includes all types of expenditure on personal consumption by the individuals of a country. It comprises expenses on durable goods like watch, bicycle, radio, etc., expenditure on single-used consumers’ goods like milk, bread, ghee, clothes, etc., as also the expenditure incurred on services of all kinds like fees for school, doctor, lawyer and transport. All these are taken as final goods.

(b)   Gross domestic private investment : Under this comes the expenditure incurred by private enterprise on new investment and on replacement of old capital. It includes expenditure on house construction, factory- buildings, and all types of machinery, plants and capital equipment.

In particular, the increase or decrease in inventory is added to or subtracted from it. The inventory includes produced but unsold manufactured and semi-manufactured goods during the year and the stocks of raw materials, which have to be accounted for in GNP. It does not take into account the financial exchange of shares and stocks because their sale and purchase is not real investment. But depreciation is added.

(c)   Net foreign investment : It means the difference between exports and imports or export surplus. Every country exports to or imports from certain foreign countries. The imported goods are not produced within the country and hence cannot be included in national income, but the exported goods are manufactured within the country. Therefore, the difference of value between exports (X) and imports (M), whether positive or negative, is included in the GNP.

(d)   Government expenditure on goods and services : The expenditure incurred by the government on goods and services is a part of the GNP. Central, state or local governments spend a lot on their employees, police and army. To run the offices, the governments have also to spend on contingencies which include paper, pen, pencil and various types of stationery, cloth, furniture, cars, etc.

It also includes the expenditure on government enterprises. But expenditure on transfer payments is not added, because these payments are not made in exchange for goods and services produced during the current year.

Thus GNP according to the Expenditure Method=Private Consumption Expenditure (C) + Gross Domestic Private Investment (I) + Net Foreign Investment (X-M) + Government Expenditure on Goods and Services (G) = C+ I + (X-M) + G.

  1. Value Added Method to GNP : Another method of measuring GNP is by value added. In calculating GNP, the money value of final goods and services produced at current prices during a year is taken into account. This is one of the ways to avoid double counting. But it is difficult to distinguish properly between a final product and an intermediate product.

For instance, raw materials, semi-finished products, fuels and services, etc. are sold as inputs by one industry to the other. They may be final goods for one industry and intermediate for others. So, to avoid duplication, the value of intermediate products used in manufacturing final products must be subtracted from the value of total output of each industry in the economy.

Thus, the difference between the value of material outputs and inputs at each stage of production is called the value added. If all such differences are added up for all industries in the economy, we arrive at the GNP by value added. GNP by value added = Gross value added + net income from abroad.

GNP at Market Prices

When we multiply the total output produced in one year by their market prices prevalent during that year in a country, we get the Gross National Product at market prices. Thus GNP at market prices means the gross value of final goods and services produced annually in a country plus net income from abroad.

GNP at Market Prices = GDP at Market Prices + Net Income from Abroad.

GNP at Factor Cost

GNP at factor cost is the sum of the money value of the income produced by and accruing to the various factors of production in one year in a country. It includes all items mentioned above under income method to GNP less indirect taxes.

GNP at market prices always includes indirect taxes levied by the government on goods which raise their prices. But GNP at factor cost is the income which the factors of production receive in return for their services alone. It is the cost of production.

Thus GNP at market prices is always higher than GNP at factor cost. Therefore, in order to arrive at GNP at factor cost, we deduct indirect taxes from GNP at market prices. Again, it often happens that the cost of production of a commodity to the producer is higher than a price of a similar commodity in the market.

In order to protect such producers, the government helps them by granting monetary help in the form of a subsidy equal to the difference between the market price and the cost of production of the commodity. As a result, the price of the commodity to the producer is reduced and equals the market price of similar commodity.

For example if the market price of rice is Rs. 3 per kg but it costs the producers in certain areas Rs. 3.50. The government gives a subsidy of 50 paisa per kg to them in order to meet their cost of production. Thus in order to arrive at GNP at factor cost, subsidies are added to GNP at market prices.

GNP at Factor Cost = GNP at Market Prices – Indirect Taxes + Subsidies.

Net National Product (NNP)

NNP includes the value of total output of consumption goods and investment goods. But the process of production uses up a certain amount of fixed capital. Some fixed equipment wears out, its other components are damaged or destroyed, and still others are rendered obsolete through technological changes.

All this process is termed depreciation or capital consumption allowance. In order to arrive at NNP, we deduct depreciation from GNP. The word ‘net’ refers to the exclusion of that part of total output which represents depreciation. So NNP = GNP—Depreciation.

NNP at Market Prices

Net National Product at market prices is the net value of final goods and services evaluated at market prices in the course of one year in a country. If we deduct depreciation from GNP at market prices, we get NNP at market prices.

NNP at Market Prices = GNP at Market Prices—Depreciation.

NNP at Factor Cost

Net National Product at factor cost is the net output evaluated at factor prices. It includes income earned by factors of production through participation in the production process such as wages and salaries, rents, profits, etc. It is also called National Income. This measure differs from NNP at market prices in that indirect taxes are deducted and subsidies are added to NNP at market prices in order to arrive at NNP at factor cost. Thus

NNP at Factor Cost = NNP at Market Prices – Indirect taxes+ Subsidies = GNP at Market Prices – Depreciation – Indirect taxes + Subsidies.

= National Income.

Normally, NNP at market prices is higher than NNP at factor cost because indirect taxes exceed government subsidies. However, NNP at market prices can be less than NNP at factor cost when government subsidies exceed indirect taxes.

Domestic Income

Income generated (or earned) by factors of production within the country from its own resources is called domestic income or domestic product.

Domestic income includes:

(i) Wages and salaries, (ii) rents, including imputed house rents, (iii) interest, (iv) dividends, (v) undistributed corporate profits, including surpluses of public undertakings, (vi) mixed incomes consisting of profits of unincorporated firms, self- employed persons, partnerships, etc., and (vii) direct taxes.

Since domestic income does not include income earned from abroad, it can also be shown as: Domestic Income = National Income-Net income earned from abroad. Thus the difference between domestic income f and national income is the net income earned from abroad. If we add net income from abroad to domestic income, we get national income, i.e., National Income = Domestic Income + Net income earned from abroad.

But the net national income earned from abroad may be positive or negative. If exports exceed import, net income earned from abroad is positive. In this case, national income is greater than domestic income. On the other hand, when imports exceed exports, net income earned from abroad is negative and domestic income is greater than national income.

Private Income

Private income is income obtained by private individuals from any source, productive or otherwise, and the retained income of corporations. It can be arrived at from NNP at Factor Cost by making certain additions and deductions.

The additions include transfer payments such as pensions, unemployment allowances, sickness and other social security benefits, gifts and remittances from abroad, windfall gains from lotteries or from horse racing, and interest on public debt. The deductions include income from government departments as well as surpluses from public undertakings, and employees’ contribution to social security schemes like provident funds, life insurance, etc.

Private Income = National Income (or NNP at Factor Cost) + Transfer Payments + Interest on Public Debt — Social Security — Profits and Surpluses of Public Undertakings.

Personal Income

Personal income is the total income received by the individuals of a country from all sources before payment of direct taxes in one year. Personal income is never equal to the national income, because the former includes the transfer payments whereas they are not included in national income.

Personal income is derived from national income by deducting undistributed corporate profits, profit taxes, and employees’ contributions to social security schemes. These three components are excluded from national income because they do reach individuals.

But business and government transfer payments, and transfer payments from abroad in the form of gifts and remittances, windfall gains, and interest on public debt which are a source of income for individuals are added to national income.

Personal Income = National Income – Undistributed Corporate Profits – Profit Taxes – Social Security Contribution + Transfer Payments + Interest on Public Debt.

Personal income differs from private income in that it is less than the latter because it excludes undistributed corporate profits.

Personal Income = Private Income – Undistributed Corporate Profits – Profit Taxes Disposable Income

Disposable income or personal disposable income means the actual income which can be spent on consumption by individuals and families. The whole of the personal income cannot be spent on consumption, because it is the income that accrues before direct taxes have actually been paid. Therefore, in order to obtain disposable income, direct taxes are deducted from personal income. Thus, Disposable Income=Personal Income – Direct Taxes.

But the whole of disposable income is not spent on consumption and a part of it is saved. Therefore, disposable income is divided into consumption expenditure and savings. Thus Disposable Income = Consumption Expenditure + Savings.

If disposable income is to be deduced from national income, we deduct indirect taxes plus subsidies, direct taxes on personal and on business, social security payments, undistributed corporate profits or business savings from it and add transfer payments and net income from abroad to it.

Disposable Income = National Income – Business Savings – Indirect Taxes + Subsidies – Direct Taxes on Persons – Direct Taxes on Business – Social Security Payments + Transfer Payments + Net Income from abroad.

Real Income

Real income is national income expressed in terms of a general level of prices of a particular year taken as base. National income is the value of goods and services produced as expressed in terms of money at current prices. But it does not indicate the real state of the economy.

It is possible that the net national product of goods and services this year might have been less than that of the last year, but owing to an increase in prices, NNP might be higher this year. On the contrary, it is also possible that NNP might have increased but the price level might have fallen, as a result national income would appear to be less than that of the last year. In both the situations, the national income does not depict the real state of the country. To rectify such a mistake, the concept of real income has been evolved.

In order to find out the real income of a country, a particular year is taken as the base year when the general price level is neither too high nor too low and the price level for that year is assumed to be 100. Now the general level of prices of the given year for which the national income (real) is to be determined is assessed in accordance with the prices of the base year. For this purpose the following formula is employed.

Real NNP = NNP for the Current Year x Base Year Index (= 100) / Current Year Index Per Capita Income

The average income of the people of a country in a particular year is called Per Capita Income for that year. This concept also refers to the measurement of income at current prices and at constant prices. For instance, in order to find out the per capita income for 2018, at current prices, the national income of a country is divided by the population of the country in that year.

Per Capita Income for 2018 = National Income for 2018/Population for 2018

Similarly, for the purpose of arriving at the Real Per Capita Income, this very formula is used.

Real Per Capita Income for 2018 =Real  National Income for 2018/Population for 2018

This concept enables us to know the average income and the standard of living of the people. But it is not very reliable, because in every country due to unequal distribution of national income, a major portion of it goes to the richer sections of the society and thus income received by the common man is lower than the per capita income.
