What is an ISIC Code?

The International Standard Industrial Classification of All Economic Activities (ISIC) is the international reference classification of productive activities. Its main purpose is to provide a set of activity categories that can be utilized for the collection and reporting of statistics according to such activities. It provides a comprehensive framework within which economic data can be collected and reported in a format that is designed for purposes of economic analysis, decision-taking, and policy-making. The classification structure represents a standard format to organize detailed information about the state of an economy according to economic principles and perceptions. These economic activities are subdivided into a hierarchical, four-level structure of mutually exclusive categories, facilitating data collection, presentation, and analysis at detailed levels of the economy in an internationally comparable, standardized way.

International Standard Industrial Classification (ISIC) Revision 5

The International Standard Industrial Classification of All Economic Activities (ISIC) has undergone a comprehensive revision to better reflect the evolving economic landscape. ISIC Revision 5 introduces updated classifications that address emerging industries and technological advancements, ensuring a more accurate representation of global economic activities. This latest revision is a critical tool for policymakers, businesses, and researchers worldwide, enabling consistent and reliable economic data analysis. By adopting ISIC Rev. 5, stakeholders can enhance their understanding of economic trends, improve international comparability, and support data-driven decision-making.

How to Read an ISIC Code

The ISIC is subdivided in a hierarchical, four-level structure. The categories at the highest level are called sections. The two-digit of the code identify the division, the third digit identifies the group and the fourth digit identifies the class.

Example
Section C
Manufacturing
Division 13
Manufacture of Textiles
Group 139
Manufacture of Other Textiles
Class 1393
Manufacture of Carpets and Rugs

History

Since its inception in 1948, the International Standard Industrial Classification (ISIC) has been a crucial framework for countries worldwide to classify economic activities. Many nations have adopted ISIC as their national standard or developed their own classifications based on ISIC. This has been instrumental in enabling the comparison of economic data on a global scale.

The latest revision, ISIC Rev. 5, further refines the classification to mirror the modern economy more accurately. It incorporates new industries and activities that have emerged over the past decade and a half. This update was shaped by extensive collaboration among experts in various fields, ensuring the classification stays relevant and useful for international comparison and economic analysis.

What are ISIC Codes used for?

ISIC codes serve as a vital tool both nationally and internationally, facilitating the classification of economic activities in various fields such as economic and social statistics, including national accounts, enterprise demographics, and employment data. These codes are indispensable for:
  • Economic and Social Statistics: ISIC codes provide a standardized method for classifying data, allowing for accurate and consistent reporting on economic activities. This includes national accounts, which track the economic performance of countries, and statistics on employment, which help monitor job trends and workforce changes.
  • Monitoring and Analysis: By offering a continuous flow of structured information, ISIC codes enable the monitoring, analysis, and evaluation of an economy's performance over time. This helps policymakers and analysts to identify trends, make informed decisions, and formulate effective policies.
  • Classification of Statistical Units: ISIC codes classify statistical units, such as establishments or enterprises, according to their primary economic activities. Each unit is assigned a unique ISIC code, ensuring that data collection, presentation, and analysis are coherent and organized.
  • Non-Statistical Uses: Beyond statistical purposes, ISIC codes are increasingly used in various non-statistical domains. These include regulatory frameworks, business directories, and economic research, providing a common language for different stakeholders to understand and compare economic activities.
  • International Comparability: ISIC codes are the globally accepted standard for categorizing economic activities, facilitating data comparison across countries and regions. This standardization helps to harmonize economic data, making it possible to conduct comparative studies and global economic analysis.
  • Improving Business and Market Insights: Businesses use ISIC codes to analyze market conditions, assess industry trends, and develop strategic plans. They help companies identify potential markets, understand competitive landscapes, and make data-driven decisions.

Why are ISIC Codes important?

ISIC codes are a crucial tool for organizing socio-economic statistics in alignment with the productive systems of the economy. They enable the efficient and accurate gathering and analysis of data, providing a comprehensive framework that supports various statistical needs.
  • Efficiency and Accuracy: ISIC codes allow for the quick and precise classification of economic activities, making data collection and analysis more efficient. This is essential for generating reliable statistics that inform economic policies and decision-making processes.
  • International Standard: Recommended to countries as an international standard, ISIC serves as a model for the development and adaptation of national activity classifications. This global adoption enhances the comparability of economic data across different nations, facilitating international economic analysis and cooperation.
  • Central Role in Economic Classifications: ISIC occupies a central position among classifications of economic activities and other related classifications, such as the Nomenclature of Economic Activities (NACE). By providing a standardized format, ISIC ensures that data on economic activities is consistent and comparable at both national and international levels.
  • Support for Policy and Decision Making: By organizing detailed economic information in a hierarchical structure of mutually exclusive categories, ISIC codes support the monitoring, analysis, and evaluation of economic performance over time. This structure aids policymakers, researchers, and businesses in making informed decisions.
  • Adapting to New Economic Realities: The latest revision, ISIC Rev. 5, addresses emerging industries and technological advancements, ensuring that the classification system remains relevant and up-to-date. This adaptability makes ISIC a vital tool for understanding and analyzing modern economic dynamics.
