Meaning of National Income

Total income earned by the residents of a country within its economic territory over a specific period, usually a year. It is derived from the agricultural, industrial, and service sectors, encompassing income earned by individuals, businesses, and the government within the country’s economy.

Concept of National Income

The concept is a fundamental measure of a country’s economic performance/growth and well-being. It quantifies the total value of goods and services produced within a nation’s borders over a specific period, usually a year. Here are the primary aspects:

Aggregate Output: National income reflects the total output of an economy, including the value of all final goods and services produced by residents and entities within the country. It represents the total production of an economy, also known as GDP.

Indicator of Economic Activity: Key indicator of a country’s economic activity, including measures of macroeconomic performance and stability. A higher national income generally indicates greater economic production and prosperity, while a lower national income may suggest economic downturns or recessions.

Measure of Standard of Living: The standard of living is a measure of the level of comfort and wealth in a nation, based on factors such as income, housing, education, and healthcare. Economists use various methods to measure it, including GDP per capita, the Human Development Index, and the Gini index. Higher national income per capita suggests that the average citizen has more resources for consumption, savings, and investment, which can contribute to a higher quality of life.

Comparison Across Time and Countries: Allows for comparisons of economic performance over time and between different countries. It provides insights into changes in production levels, economic growth rates, and relative living standards across nations.

Basis for Economic Policy: Economic policy addresses what, how, and for whom to produce at the macro level. Policymakers use national income data to formulate and evaluate policies promoting economic growth, employment, and stability.

Components: The concept includes components such as consumption expenditure, investment, government spending, and net exports, providing insights into a country’s economic activity.

Income Distribution: The data of the concept provides insight into income distribution within a society, which can impact economic growth and social cohesion. It’s crucial to analyze not only the total income of the nation but also its distribution among different population segments.

Estimation of National Income in India: History & Background

The calculation of India’s national income has a rich history. The first attempt was made by Dadabhai Naoroji in 1867-68, followed by the establishment of the first scientific method by Professor VKRV Rao in 1931-32. The National Income Committee, led by Professor FC Mahalanobis in 1949, also made an official attempt at this calculation. Since 1949, the Central Statistical Organization, which has since been renamed the Central Statistical Office, has been responsible for formulating India’s national income. Besides, it’s important to note that in India, the financial year runs from 1 April to 31 March.

Methods for Estimating National Income

The calculation of national income commonly employs three methods: the product method, the income method, and the expenditure method.

Product Method

It involves calculating the total money value of goods and services produced by the primary, secondary, and tertiary sectors. It allows for an assessment of the contribution of each sector to the national income.

Income Method

Determined based on factors such as rent, wages, interest, and profit, which are the rewards for the factors of production. This method provides insight into the contribution of each factor of production to the national income.

Expenditure Method

The expenditure method estimates national income by calculating the expenditures incurred by individuals, firms, and the government within a specific year. It involves summing up consumption expenditure, investment expenditure, and government expenditure to arrive at the total expenditure.

Formula for Calculating National Income

Understanding national income is crucial for comprehending a nation’s economic health. It can be calculated using the expenditure method, which involves summing up consumption, investment, government spending, and net exports.

The formula for calculating national income (Y) using the expenditure method is as follows:

National Income (Y) = Consumption (C) + Investment (I) + Government Spending (G) + (Exports (X) – Imports (M))

Various Types of Economic Indicators

The key concepts associated with the concept include:

Gross Domestic Product (GDP): Gross Domestic Product (GDP) is a measure of a country’s income, representing the total value of all goods and services produced within its borders. It is categorized into consumption, investment, government spending, and net exports. GDP calculation includes the income of foreigners in a country but excludes the income of citizens living outside of that country.

Gross National Product (GNP): GNP measures the total value of goods and services produced by a country’s residents, including income from foreign investments. The formula for GNP is GNP = GDP + X – M, where X is the income of a country’s residents living abroad and M is the income of foreigners living in the country.

Net National Product (NNP): Net National Product (NNP) is calculated by subtracting depreciation from Gross National Product (GNP). This provides a more accurate representation of a nation’s economic output by accounting for the wear and tear on capital goods. Depreciation charges address the cost of this wear and tear. NNP = GNP – Depreciation.

Personal Income: Personal income refers to the total income received by individuals from various sources, including wages, salaries, interest, dividends, and transfer payments (e.g., social security benefits and welfare payments).

• Personal Income = National Income – (Undistributed Corporate Profits + Corporate Taxes + Social Security Contribution) + (Transfer Payments).
• Transfer Payments are payments that are not against any productive work. (Example- Old Age Pension, Unemployment compensation etc.) 

Disposable Income: Disposable income is the amount of money that households have available for spending and saving after taxes have been deducted. It offers insight into the resources available for household consumption and savings.

• Disposable Personal Income = Personal Income – Direct Taxes

National Disposable Income: National Disposable Income is calculated as the Net National Product at market prices plus other current transfers from the rest of the world. It represents the maximum amount of goods and services available to the domestic economy. Current transfers from the rest of the world include items such as gifts and aids.

Factor Cost: Factor Cost refers to the cost of factors of production incurred by a firm when producing goods and services. It does not include taxes paid to the government, but subsidies received are included in the factor cost.

Market Price: Market Price is the current price at which an asset or service can be bought or sold. It is calculated as the factor cost plus net indirect taxes, where net indirect taxes are equal to indirect taxes minus subsidies.

In India, NNP at FC is referred to as National Income.

Nominal GDP: Nominal GDP is measured based on the current price of the current year.

Real GDP: Real GDP is calculated based on fixed prices in the base year.

GDP Deflator: The GDP Deflator gives us an idea of how prices have moved from the base year to the current year. It measures the change in prices while keeping the volume of production fixed.

Gross Value Added (GVA): GVA is the measurement of the value of goods and services produced in a specific area, industry, or sector of an economy. It is used to measure the contribution of a corporate subsidiary, company, or municipality to an economy, producer, sector, or region. GVA is calculated as GDP plus subsidies on products minus taxes on products.
