DescriptionISIC Rev.4 is a standard classification of economic activities arranged so that entities can be classified according to the activity they carry out. The categories of ISIC at the most detailed level (classes) are delineated according to what is, in most countries, the customary combination of activities described in statistical units and considers the relative importance of the activities included in these classes. While ISIC Rev.4 continues to use criteria such as input, output and use of the products produced, more emphasis has been given to the character of the production process in defining and delineating ISIC classes.

The groups and divisions, the successively broader levels of classification, combine the activities of producing units according to: similarities in the character of the goods and services produced, the uses to which the goods and services are put, and the inputs, process and technology of production.

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.

In providing more up-to-date detail, this revision of the classification provides a closer representation of current economic reality. In addition, the Revision 4 of ISIC has improved comparability with other regional activity classifications in use around the world.
