Classification of Economic Activities, Edition 1993 (WZ 93)
Up to the end of 2002, the WZ 93 was used to cover in a uniform way the economic activities of enterprises, local units and other statistical units in all official statistics. At the beginning of 2003, it was replaced by the Classification of Economic Activities, Edition 2003 (WZ 2003). However, a version including explanations and an alphabetic index with over 30,000 keywords are still available as a print version and for download to help in applying the WZ 93.
The complete breakdown of the WZ 93 is available here for free download (.pdf, 163 KB) for your internal use.
To read the file, you need the Acrobat Reader program, which may also be downloaded free of charge at Adobe.
The complete Classification of Economic Activities, Edition 1993, incl. Explanations, may be obtained as a print version and as a download - just as the alphabetic index, various conversion tables and an Excel version of the breakdown - from the Federal Statistical Office.
