When it comes to measuring the economic health and performance of a country, two key indicators stand out: GDP (Gross Domestic Product) and GNI (Gross National Income). While they both offer insights into an economy’s vitality, they approach the task from different angles. In this article, we’ll delve into the intricacies of GDP and GNI, exploring their definitions, calculations, significance, and the unique aspects each brings to the table.
Difference Between GDP and GNI (with Comparison Chart)
| Aspect | GDP (Gross Domestic Product) | GNI (Gross National Income) |
|---|---|---|
| Definition | Total value of goods and services produced within a country’s borders over a specific period. | Total income earned by a country’s residents, including income from domestic and international sources. Includes net income from abroad. |
| Focus | Economic activity within the country’s borders. | Income earned by residents, whether earned domestically or abroad. |
| Components | Production, income, and expenditure approaches. | GDP plus net income from abroad (earnings from foreign investments minus payments to foreign investors). |
| Calculation | GDP = Consumption + Investment + Government Spending + (Exports – Imports) | GNI = GDP + Net Income from Abroad |
| Includes | Domestic production by both domestic and foreign entities. | Net income earned from abroad, including compensation of employees and property income. |
| Excludes | Production of domestic entities operating abroad. | Economic activity by foreign entities within the country. |
| Reflects | Economic output and activity within the country. | Income earned by the country’s residents, whether within the country or internationally. |
| Use cases | Measuring the size and growth of an economy. | Assessing the economic well-being of a country’s residents and their connection to the global economy. |

What Is GDP?
GDP (Gross Domestic Product) is the total value of goods and services produced within a country’s borders during a specific period, typically a year. GDP measures the economic activity generated by residents and non-residents within a country’s geographic borders. It includes all final goods and services produced within the country, regardless of the nationality of those producing them.
What Is GNI?
GNI (Gross National Income), on the other hand, is the total income earned by a country’s residents, both domestically and abroad, during a specific period, typically a year. It measures the income generated by the factors of production (such as labor and capital) owned by a country’s residents. GNI includes income earned by a country’s residents from investments and work done abroad, but it excludes income earned by non-residents within the country.
let’s consider an example to better understand the difference between GDP and GNI.
Suppose a company called XYZ, which is headquartered in the United States, operates in three countries: the United States, Canada, and Mexico. In the United States, the company generates $1 million in revenue, in Canada it generates $500,000, and in Mexico it generates $250,000. The company has 10 employees in the United States who earn an average salary of $50,000, and 5 employees in Canada and Mexico who earn an average salary of $25,000.
Based on this information, we can calculate the GDP and GNI for the United States as follows:
- GDP: The total value of goods and services produced within the United States is $1 million. Therefore, the GDP of the United States is $1 million.
- GNI: The income generated by residents of the United States is the sum of the income earned by the company’s employees and the income earned from investments abroad. The income earned by the company’s employees in the United States is $500,000 (10 employees * $50,000 salary). The income earned by the company’s employees in Canada and Mexico is $125,000 (5 employees * $25,000 salary * 2 countries). Therefore, the total income earned by residents of the United States is $625,000 ($500,000 + $125,000).
In this example, the GDP of the United States is $1 million, while the GNI is $625,000.
Calculating GDP and GNI: Approaches and Formulas
GDP can be calculated using three distinct approaches: the production approach, the income approach, and the expenditure approach. The production approach tallies the value added at each stage of production across all industries. The income approach computes the sum of all incomes earned by individuals and businesses, including wages, profits, rents, and taxes minus subsidies. Lastly, the expenditure approach tallies all spending on consumption, investment, government purchases, and net exports (exports minus imports).
GNI is derived by taking GDP and factoring in net income from abroad. This includes two main components: net compensation of employees (the difference between income earned by a country’s residents abroad and foreigners within the country) and net property income (the balance between income earned by domestic residents from foreign-owned assets and income earned by foreign residents from domestic-owned assets).
FAQs
1. What is GDP?
GDP stands for Gross Domestic Product. It is a measure of the total economic output or the total value of goods and services produced within a country’s borders during a specific time period, usually a year or a quarter.
2. What is GNI?
GNI stands for Gross National Income. It represents the total income earned by a country’s residents, including individuals, businesses, and government, both domestically and internationally. GNI includes GDP and adds or subtracts net income from abroad.
3. How is GDP calculated?
GDP can be calculated using three approaches: the production approach, the income approach, and the expenditure approach. The production approach adds up the value added at each stage of production. The income approach sums up all the incomes earned by residents. The expenditure approach adds up all spending on consumption, investment, government purchases, and net exports (exports minus imports).
4. How is GNI calculated?
GNI is calculated by adding net income from abroad to GDP. Net income from abroad includes net compensation of employees (income earned from abroad by residents minus income earned domestically by foreigners) and net property income (income earned from foreign-owned assets minus income earned by foreign residents from domestic-owned assets).
5. What does GDP represent?
GDP represents the total economic activity and output that occurs within a country’s borders. It reflects the production of goods and services by domestic and foreign entities operating within the country.
6. What does GNI represent?
GNI represents the total income earned by a country’s residents, regardless of whether it was earned domestically or internationally. It provides a broader perspective on the economic well-being of a nation’s citizens.
7. Why is GDP important?
GDP is important because it serves as a key indicator of a country’s economic performance and growth. It helps policymakers, economists, and analysts make informed decisions about economic policies and strategies.
8. Why is GNI important?
GNI is important because it offers a more comprehensive view of a nation’s economic well-being. It considers both domestic and international sources of income, providing insights into the standard of living and the benefits citizens derive from participating in the global economy.
9. How do GDP and GNI differ in their scope?
GDP focuses exclusively on economic activity within a country’s borders, while GNI takes into account income earned by residents both domestically and internationally.
10. Can a country have a higher GDP but a lower GNI, or vice versa?
Yes, it is possible. For example, if a country has a significant amount of income earned from foreign investments, its GDP may be higher than its GNI if the net income from abroad is negative. Similarly, a country with a large amount of income earned from abroad could have a higher GNI than GDP.
11. Which indicator is more suitable for assessing the well-being of citizens?
GNI is generally considered more suitable for assessing the well-being of citizens because it reflects the actual income earned by residents, regardless of where it was earned. It provides a more accurate representation of the economic benefits received by citizens, including income earned from abroad.
12. How can GDP and GNI be used together for economic analysis?
Using both GDP and GNI together provides a more comprehensive understanding of an economy. While GDP measures production and economic activity within a country, GNI adds the dimension of income earned by residents, giving a fuller picture of economic well-being and the country’s integration into the global economy.
These FAQs provide a solid foundation for understanding the key differences between GDP and GNI and their significance in the field of economics.
