Introduction
National income accounts represent a system of accounts that show the main aggregates relating to a nation’s income and its components. These components include Gross Domestic Product (GDP), Gross National Product (GNP), national income after deducting capital consumption, and details about consumption, investment, government expenditure, exports, and imports. National income accounts often include information on stocks and flows, price levels, and various economic aggregates at both current and constant prices.
Historical Context
The concept of national income accounting dates back to the 17th century but gained prominence during the 1930s. The modern system of national income accounting was developed by economists such as Simon Kuznets in the United States during the Great Depression to provide a comprehensive overview of economic activity.
Types/Categories
- Gross Domestic Product (GDP):
- The total value of all goods and services produced within a country’s borders in a specific time period.
- Gross National Product (GNP):
- The total value of goods and services produced by a country’s residents, regardless of the location of production.
- Net National Product (NNP):
- GNP minus depreciation.
- National Income (NI):
- NNP minus indirect taxes.
Key Events
- The Great Depression (1930s): Highlighted the need for comprehensive economic data.

Detailed Explanations
Gross Domestic Product (GDP)
GDP can be measured in three ways: production approach, income approach, and expenditure approach. The formula for GDP using the expenditure approach is:
Where:
- \(C\) = Consumption
- \(I\) = Investment
- \(G\) = Government Spending
- \(X\) = Exports
- \(M\) = Imports
Gross National Product (GNP)
GNP includes GDP plus net income from abroad:
