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 across different countries and industries. By standardizing classifications, ISIC helps governments, researchers, and businesses understand economic trends and make informed decisions. ISIC is widely used in various fields, including economics, statistics, and business analysis. It allows for consistent reporting and comparison of industrial data, facilitating international trade and investment. The classification is periodically updated to reflect changes in the global economy and emerging industries.
