National Income Accounting is a method used to measure and analyze the economic activity of a country or region. It involves the collection, recording, and analysis of economic data to determine the size and composition of a country’s economy, and to track changes in economic activity over time.
National Income Accounting involves the use of various economic indicators, such as Gross Domestic Product (GDP), Gross National Product (GNP), National Income (NI), and Disposable Income (DI), to provide a comprehensive picture of the economic activity of a country or region.
The primary goal of National Income Accounting is to provide a quantitative measure of economic activity that can be used to assess the performance of a country’s economy, to compare the economic performance of different countries, and to identify trends in economic activity over time. This information is useful for policymakers, businesses, and investors, as it provides a basis for making informed decisions about economic policy, investment strategy, and business operations.

GDP
Gross Domestic Product (GDP) is a measure of the total economic output of a country. It represents the monetary value of all goods and services produced within a country’s borders over a specified period, usually a year or a quarter.
GDP is an important indicator of the economic performance of a country and is used to measure the size and growth rate of its economy. It can also be used to compare the relative economic performance of different countries.
Nominal GDP
Nominal GDP, also known as current-Rupee GDP, is a measure of Gross Domestic Product (GDP) that is not adjusted for inflation. It represents the total value of all goods and services produced within a country’s borders, measured in current prices.
Nominal GDP can be useful for measuring the total output of an economy over time and for comparing the size of different economies. However, it does not account for changes in the price level of goods and services, which can make it difficult to compare GDP figures across different time periods or countries with different inflation rates.
To make meaningful comparisons of GDP over time, economists often use real GDP, which is adjusted for inflation. This allows for a more accurate comparison of economic growth between different periods and helps to account for changes in the purchasing power of a currency.
Real GDP
Real GDP, also known as inflation-adjusted GDP, is a measure of Gross Domestic Product (GDP) that has been adjusted for inflation. Real GDP reflects the total value of all goods and services produced within a country’s borders, measured in constant prices, which means prices adjusted for inflation.
Real GDP is a more accurate measure of economic output over time because it takes into account changes in the price level of goods and services. By adjusting for inflation, it allows economists and policymakers to compare economic growth across different time periods and to make meaningful comparisons of economic performance between different countries.
GDP Deflator
The GDP deflator is a measure of the price level of goods and services included in Gross Domestic Product (GDP). It is used to adjust nominal GDP to arrive at real GDP, which reflects changes in the quantity of goods and services produced rather than just changes in prices.
The GDP deflator is calculated by dividing nominal GDP by real GDP and multiplying by 100. The result is a measure of the overall price level of goods and services produced in an economy, relative to a base year. For example, if the GDP deflator for a particular year is 120, this means that the overall price level of goods and services produced in that year is 20% higher than the price level in the base year.
Difference between Nominal GDP and Real GDP
| Nominal GDP | Real GDP |
|---|---|
| Measures the total value of goods and services produced in an economy at current market prices | Measures the total value of goods and services produced in an economy at constant prices |
| Does not adjust for changes in the price level of goods and services | Adjusts for changes in the price level of goods and services |
| Can be used to compare the total output of an economy over time and between countries | Provides a more accurate measure of economic growth over time and between countries by accounting for inflation |
| Does not account for changes in the purchasing power of a currency | Accounts for changes in the purchasing power of a currency |
| Can be affected by changes in the price level of goods and services, which can make it difficult to compare GDP figures across different time periods or countries with different inflation rates | Allows for a more accurate comparison of economic growth between different periods and helps to account for changes in the purchasing power of a currency |
What is Base Year
A base year is a reference point used for calculating economic indicators such as inflation, Gross Domestic Product (GDP), and other economic statistics. In the context of these indicators, the base year represents a benchmark against which future changes are measured. For example, when calculating real GDP, the base year is used as a reference point to adjust for changes in the price level of goods and services. The GDP figures from the base year are used as the basis for comparison with subsequent years to arrive at a measure of real GDP that accounts for inflation.
The choice of base year can have important implications for economic analysis and policymaking. The base year should ideally be a year with stable economic conditions, such that the GDP figures reflect changes in the quantity of goods and services produced rather than just changes in prices.
What is Base Effect?
The base effect refers to the impact of changes in the base year used for calculating GDP. The base year is a reference year against which the growth of the economy is measured. The GDP in any given year is expressed in terms of the prices prevailing in the base year.
When there is a change in the base year, the GDP figures for all the subsequent years will be recalculated using the new base year. This can result in significant changes in the GDP figures, even if there is no real change in the level of economic activity.
For example, suppose the base year for calculating GDP is 2010, and the GDP for 2020 is estimated to be Rs. 100 crore. If the base year is changed to 2015, and the GDP for 2020 is recalculated using the new base year, the GDP figure may be significantly higher or lower than Rs. 100 crore, depending on the changes in the price levels of goods and services between 2010 and 2015.
Therefore, when analyzing changes in GDP figures over time, it is important to take into account the base effect, as changes in the base year can distort the true picture of economic growth or contraction.
What is Market Price?
Market price refers to the price at which goods and services are bought and sold in a competitive marketplace. It is the final price of the product or services after adding taxes. It is determined by the forces of supply and demand in the market and can fluctuate over time as these forces change.
What is factor cost?
Factor cost refers to the cost of the factors of production used to produce goods and services, including labor, capital, and raw materials. It represents the actual cost incurred by producers to produce goods and services, excluding indirect taxes and subsidies.
In the context of national income accounting, factor cost is used to measure Gross Domestic Product (GDP) from the perspective of producers, rather than from the perspective of consumers. It is calculated by subtracting indirect taxes and adding subsidies from market prices.
Methods of GDP Estimation
There are three primary methods used to estimate Gross Domestic Product (GDP), each of which provides a different perspective on economic activity. These methods are:
- The Production Approach: This method estimates GDP by adding up the value of all goods and services produced in an economy over a given period of time. This includes the value of final goods and services produced by businesses and government agencies, as well as the value of goods and services produced for personal consumption or investment.
- The Expenditure Approach: This method estimates GDP by adding up all the spending on goods and services in an economy over a given period of time. This includes consumer spending, investment spending, government spending, and net exports (exports minus imports).
- The Income Approach: This method estimates GDP by adding up all the income earned by individuals and businesses in an economy over a given period of time. This includes wages and salaries, profits, rents, and interest payments.
Each of these methods provides a slightly different perspective on economic activity, and the estimates generated by each method may differ. However, they should ultimately provide similar estimates of GDP when calculated correctly. In practice, national statistical agencies typically use a combination of these methods to arrive at a more accurate estimate of GDP. The specific methods used can vary depending on the country and the availability of data.
Who calculates GDP in India?
In India, the Central Statistics Office (CSO) under the Ministry of Statistics and Programme Implementation is responsible for calculating GDP. The CSO collects data on economic activity from various sources, including government departments, industry associations, and surveys of households and businesses. The data is then used to estimate the size and composition of the economy and to calculate key economic indicators such as GDP, GVA, and NNP. The CSO releases GDP estimates on a quarterly basis, which are used by policymakers, businesses, and investors to assess the performance of the economy and to make informed decisions about economic policy, investment strategy, and business operations.
‘Tax-To-GDP Ratio
The Tax-to-GDP ratio is a measure of the total amount of taxes collected by a government as a percentage of the country’s Gross Domestic Product (GDP). It is used as an indicator of the size of the government’s tax revenue relative to the size of the overall economy. A higher Tax-to-GDP ratio generally indicates a larger tax burden on the economy, while a lower ratio indicates a smaller tax burden.
The Tax-to-GDP ratio is an important metric for policymakers, as it provides a measure of the government’s ability to generate revenue from its tax system. A high Tax-to-GDP ratio can be an indication of a well-functioning tax system that is able to raise sufficient revenue to fund government programs and services. However, it can also be a sign of a heavy tax burden on the economy, which can discourage economic growth and investment.
Conversely, a low Tax-to-GDP ratio may indicate a relatively small tax burden on the economy, which can encourage economic growth and investment. However, it can also indicate a weak tax system that is not generating sufficient revenue to fund government programs and services.
The Tax-to-GDP ratio can also be used to compare the tax systems of different countries. Countries with similar levels of economic development and size may have different Tax-to-GDP ratios, reflecting differences in tax policy and the structure of the economy. As such, the Tax-to-GDP ratio can be a useful tool for policymakers and analysts to assess the effectiveness and efficiency of a country’s tax system.
Rank of India in terms of Real GDP
According to the International Monetary Fund (IMF) data for 2021, India is ranked 6th in terms of Real GDP. The top five countries ranked ahead of India are the United States, China, Japan, Germany, and the United Kingdom.
State with largest GDP in India
According to the latest available data from the Ministry of Statistics and Programme Implementation, the state of Maharashtra has the highest Real GDP among all Indian states. Maharashtra’s Real GDP for the year 2020-21 was estimated to be approximately Rs. 32.2 lakh crore. Other states with high Real GDP include Tamil Nadu, Uttar Pradesh, Karnataka, Gujarat, and Andhra Pradesh.
Real GDP growth rate of India
The Real GDP growth rate of India in the last 10 years has been as follows:
- 2012-13: 5.5%
- 2013-14: 6.4%
- 2014-15: 7.4%
- 2015-16: 8.2%
- 2016-17: 7.2%
- 2017-18: 6.8%
- 2018-19: 6.5%
- 2019-20: 4.0%
- 2020-21: -7.7%
- 2021-22 (est.): 9.5% (as per the latest projections by the Reserve Bank of India)
It’s important to note that the COVID-19 pandemic has significantly impacted India’s GDP growth rate, with a contraction in the economy in 2020-21. However, the economy is expected to recover in the coming years with a higher growth rate.
What is Green GDP
Green GDP, on the other hand, attempts to include the costs of these environmental damages into the calculation of GDP. This can be done by subtracting the economic costs of environmental degradation from the traditional GDP, thus producing a more accurate measure of the overall economic well-being of a country that takes into account the environmental costs.
Green GDP is often used by policymakers and economists to evaluate the sustainability of economic growth and development over the long term, as it provides a more comprehensive understanding of the economic, social, and environmental impacts of economic activities.
Problems in GDP Estimation
There are several problems in GDP calculations, some of which include:
- Exclusion of Non-Market Activities: GDP only includes the value of goods and services produced in the market, leaving out non-market activities such as household production, volunteer work, and black-market activities.
- Environmental Impact: GDP does not account for the environmental impact of economic activity, including the depletion of natural resources, pollution, and other negative externalities.
- Income Inequality: GDP measures the overall size of an economy but does not take into account the distribution of income among individuals. A country with high GDP may still have significant income inequality.
- Quality of Life: GDP does not capture the quality of life of a population, including factors such as health, education, and social well-being.
- Underground Economy: GDP calculations may underestimate the true size of the economy if a significant portion of economic activity is taking place in the underground economy.
- Asset Price Inflation: GDP does not capture changes in the value of assets, such as real estate or stocks, which can contribute to economic growth but may not necessarily improve the well-being of the population.
- Globalization: GDP does not account for the international dimensions of economic activity, such as cross-border trade and investment, which are becoming increasingly important in today’s globalized economy.
GNP
GNP stands for Gross National Product. It is a measure of the total economic output produced by the citizens and businesses of a country, regardless of their location, during a specific period of time. GNP includes all final goods and services produced by a country’s residents, regardless of whether they are produced within the country’s borders or outside of them.
GNP is calculated by adding up the value of all final goods and services produced by a country’s residents, including those produced abroad, and subtracting the value of goods and services produced by non-residents within the country’s borders. GNP can be calculated using the following formula:
GNP = C + I + G + (X-M) + NFP
Where:
C = Private consumption expenditures
I = Gross investment
G = Government spending
(X-M) = Net exports (exports minus imports)
NFP = Net factor payments to the rest of the world (income earned by domestic residents from foreign sources minus income earned by foreign residents from domestic sources)
GNP is similar to Gross Domestic Product (GDP), which measures the total economic output produced within a country’s borders during a specific period of time, but they differ in that GNP takes into account the production of a country’s citizens and businesses regardless of their location, while GDP only takes into account production within a country’s borders.
NNP
NNP stands for Net National Product, which is a measure of the total economic output produced by the citizens and businesses of a country after accounting for depreciation of capital goods during a specific period of time. NNP represents the net value of a country’s economic output, which takes into account the wear and tear on the country’s capital stock.
NNP is calculated by subtracting the depreciation of capital goods from Gross National Product (GNP). The formula for NNP is as follows:
NNP = GNP – Depreciation
Where Depreciation refers to the loss in value of capital goods such as machinery, equipment, and buildings due to wear and tear, obsolescence, and other factors.
NNP is considered to be a more accurate measure of a country’s economic output than GNP, as it takes into account the fact that capital goods wear out and need to be replaced over time. It represents the income available to a country’s citizens and businesses for consumption and investment purposes after accounting for the depreciation of the country’s capital stock.
National Income
National Income refers to the total income earned by the citizens and businesses of a country during a specific period of time, usually a year. National Income is calculated by the Net National Product at facto cost, (NNP – Taxes + Subsidy).
