ISIC
ISIC (Rev.4) stands for International Standard Industrial Classification of all economic activities, the most complete and systematic industrial classification made by United Nations Statistics Division.
ISIC 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.
