The purpose of this list is to record occupations held by persons according to a commonly used international classification system.

This list is based on "Supporting Document H: List of Occupations" (1).

This list has been adapted from the International Standard Classification of Occupations (ISCO-88) (2). This standard of the International Labour Organisation (ILO) is widely used by various national governmental bodies (Ministry of Labour, Statistical Office) in developing their Standard Classification of Occupations.

The original codes from the Supporting Document are included in the column 1st ed. Code. The Source Code in the fourth column is the code used in the International Standard Classification of Occupations (ISCO-88).

This is a hierarchical list with four levels, as described in Rule No. 3 in the Introduction.

This Micro-thesaurus is used for field 922 Occupation (ILO Categories) in the Person format

Groups wishing to record occupations according to their own list can use field 923 Local Term for Occupation in the Person format. Guidelines for compiling such a list and a sample Micro-thesaurus can be found in this volume, as Micro-thesaurus 64: Local Terms for Occupations.
