Standard classification systems used to identify and manipulate information are often referred to as 'nomenclatures'. They are also commonly called 'classifications'. This guide provides links to the most commonly used international classification standards.
Classifications are the foundations on which all statistical systems, national as well as international, are built. Thus, it is essential that statisticians have access to an extensive, reliable and regularly updated source of information on classification systems for use with data such as industrial, foreign trade or occupational data.
