The International Standard Industrial Classification of All Economic Activities is a United Nations system for classifying economic data. The United Nations Statistics Division describes it in the following terms:

Wide use has been made of ISIC, both nationally and internationally, in classifying data according to kind of economic activity in the fields of production, employment, gross domestic product and other statistical areas. ISIC is a basic tool for studying economic phenomena, fostering international comparability of data, providing guidance for the development of national classifications and for promoting the development of sound national statistical systems.
