International Standard Industrial Classification (ISIC) is a globally recognized framework developed by the United Nations to categorize economic activities systematically. It provides a standardized way for countries, statistical agencies, researchers, and policymakers to classify industries and economic activities consistently across borders. This uniform classification system is essential for compiling, analyzing, and comparing economic data on an international scale, facilitating informed decision-making and fostering global economic cooperation.
In this comprehensive guide, we will explore the origins, structure, applications, and importance of ISIC, ensuring you gain a thorough understanding of this vital classification system.
Origins and Development of ISIC
Historical Background
The International Standard Industrial Classification was first introduced in 1948 by the United Nations to promote comparability of economic data across countries. Since its inception, ISIC has undergone several revisions to reflect changes in the global economy, technological advancements, and evolving industry structures.
Evolution of ISIC
- ISIC Revision 1 (1958): The first major update, refining classifications based on industrial activities.
- ISIC Revision 2 (1968): Improved detail and expanded categories to capture more industries.
- ISIC Revision 3 (1989): Major overhaul to align with new economic realities, including the rise of service industries.
- ISIC Revision 4 (2008): The latest version, incorporating technological changes, digital economy, and environmental considerations.
Objectives of ISIC Development
- Standardize industrial classification worldwide.
- Facilitate international comparison of economic data.
- Support economic analysis, policymaking, and research.
- Improve data collection efficiency and accuracy.
Structure of the ISIC System
Hierarchical Classification
ISIC employs a hierarchical structure, allowing data to be classified at varying levels of detail:
1. Sections: The broadest categories, represented by a single letter (e.g., A, B, C).
2. Divisions: More specific groups within sections, numbered from 01 to 99.
3. Groups: Subcategories within divisions, denoted by the division number followed by a decimal point and a digit (e.g., 01.1).
4. Classes: The most detailed level, providing specific industry descriptions (e.g., 01.11).
This structure enables flexibility in data analysis, from broad sectoral overviews to detailed industry studies.
Main Sections of ISIC
ISIC divides economic activities into ten main sections:
| Section Letter | Description | Examples of Activities |
|------------------|----------------------------------------------|--------------------------------------------|
| A | Agriculture, Forestry, and Fishing | Crop production, logging, fishing |
| B | Mining and Quarrying | Mineral extraction, oil and gas |
| C | Manufacturing | Food processing, textiles, machinery |
| D | Electricity, Gas, Steam, and Air Conditioning | Power generation, gas supply |
| E | Water Supply; Sewerage, Waste Management | Water treatment, waste collection |
| F | Construction | Building, civil engineering |
| G | Wholesale and Retail Trade; Repair of Motor Vehicles and Motorcycles | Retail stores, wholesale markets |
| H | Transportation and Storage | Rail, road, air transport |
| I | Accommodation and Food Service Activities | Hotels, restaurants |
| J | Information and Communication | Telecom, IT services |
Key Components and Categories of ISIC
Sections and Divisions
Each section contains multiple divisions, which are numbered to reflect their position within the broader sector. For example:
- Section C: Manufacturing
- Division 10: Manufacture of food products
- Division 13: Manufacture of textiles
Groups and Classes
Within each division, groups provide more specific categorization:
- Division 10:
- Group 10.1: Processing and preserving of meat and meat products
- Group 10.2: Processing and preserving of fish, crustaceans, and mollusks
And further, classes specify particular activities:
- Class 10.11: Processing and preserving of meat
- Class 10.12: Processing and preserving of fish
Example Hierarchy
To illustrate, here’s an example of classification for a specific activity:
- Section: C (Manufacturing)
- Division: 10 (Manufacture of food products)
- Group: 10.1 (Processing and preserving of meat and meat products)
- Class: 10.11 (Processing and preserving of meat)
This hierarchical system allows for precise categorization suited for various analytical needs.

Importance of ISIC in the Global Economy
Enhances Data Comparability
A standardized classification system like ISIC ensures that economic data from different countries are comparable, which is crucial for global economic analysis and policy coordination.
Supports Sustainable Development Goals (SDGs)
By categorizing industries based on their activities, ISIC helps monitor progress toward SDGs, especially in sectors related to industry, innovation, and infrastructure.
Promotes Economic Transparency
Clear classification fosters transparency and accountability in economic reporting, attracting foreign investment and fostering international cooperation.
Facilitates Research and Innovation
Researchers use ISIC to analyze industry dynamics, technological advancements, and innovation trends across sectors and countries.
Challenges and Limitations of ISIC
Rapid Economic Changes
The fast pace of technological innovation and the emergence of new industries, especially digital and green economy sectors, require frequent updates to the classification system.
Complexity and Granularity
While detailed classifications are useful, they can also lead to complexity, making data collection and analysis challenging for some stakeholders.
Variations in Implementation
Differences in how countries adopt and adapt ISIC can lead to inconsistencies, reducing comparability.
Need for Regular Updates
To remain relevant, ISIC must be continually revised, which requires resources and international consensus.
