The International Standard Industrial Classification (ISIC) is a system developed by the United Nations to categorize economic activities. It provides a framework for collecting, analyzing, and comparing data related to industries across different countries. ISIC helps in understanding the structure of economies and facilitates international trade and investment. ISIC is organized into sections, divisions, groups, and classes, allowing for detailed classification of industries. This standardized approach aids governments, researchers, and businesses in making informed decisions based on industry trends and economic performance. It is widely used in statistical reporting and economic analysis globally.
