Relationship to international standards
3 (a)Is this classification based on (or linked to) an international standard classification? If yes, please describe.WZ 2008 is based on the Statistical Classification of Economic Activities in the European Community (NACE Rev. 2), which itself is based on the International Standard Industrial Classification (ISIC Rev. 4).
3 (b)Is the classification structure identical to the international standard or, if not, how does it differ? (e.g. have additional levels been added to the international standard or have changes been made within the level of the international structure, such as aggregations or additional breakdowns)NACE Rev. 2 has been extended by one national level (five-digit subclasses). In NACE Rev. 2 itself the three-digit and four-digit groups and classes of ISIC Rev. 4 have sometimes been subdivided with differing codes. A clear regrouping into the groups and classes of ISIC Rev. 4 is always possible.
3 (c)Please describe deviations from the international standard (in terms of structure, methodology or application rules). Please use examples, if a general statement is not possible.See above.
Classification rules for outsourcing are more detailed and more strict, identical with the rules described in NACE Rev. 2.
3 (d)At what level of the international standard can data be reported for international comparison? (Please provide examples of programmes / indicators if reporting takes place at different levels of the classification.)Different levels of ISIC Rev. 4; at least division level, for most data also group and class level. Number of enterprises and local units, number of employees, turnover can be reported for ISIC Rev. 4 classes for example.
