- 104 Minor Groups
- 400 Unit Groups
- 1,124 Occupations
2 (b)Please provide examples of the coding system used at each level.- Major Group: Highest level of aggregation, with each major group being denoted by a single corresponding one-digit or -alphabetical code, i.e. 1, 2, 3, 4, 5, 6, 7, 8, 9 or X.
- Sub-major Group: Sub-divisions of the major groups, consisting of 2-digit codes.
- Minor Group: Sub-divisions within the sub-major groups, consisting of 3-digit codes.

Relationship to international standards
3 (a)Is this classification based on (or linked to) an international standard classification? If yes, please describe.International Standard Classification of Occupations 2008 (ISCO-08)
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)The SSOC 2010 adopts the basic framework of, and is closely aligned with, the ISCO-08. However, the SSOC 2010 has one more level of classification, with the most detailed at the 5-digit level.
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.While the SSOC 2010 adheres closely to the structure of the ISCO-08, appropriate deviations were made to take into account Singapore’s local context. For example, the SSOC does not contain the ISCO code 1113 ‘Traditional Chiefs and Heads of Village’ as such occupations are not applicable in Singapore’s context. Similarly, selected occupations such as nurses and other allied health professionals (e.g. physiotherapists, dieticians, speech therapists, optometrists) are classified under Major Group 3 Associate Professionals and Technicians as these occupations generally do not require tertiary education at the university or postgraduate university level in Singapore.
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.)While the SSOC 2010 adheres closely to the structure of the ISCO-08, appropriate deviations were made to take into account Singapore’s local context. For example, the SSOC does not contain the ISCO code 1113 ‘Traditional Chiefs and Heads of Village’ as such occupations are not applicable in Singapore’s context. Similarly, selected occupations such as nurses and other allied health professionals (e.g. physiotherapists, dieticians, speech therapists, optometrists) are classified under Major Group 3 Associate Professionals and Technicians as these occupations generally do not require tertiary education at the university or postgraduate university level in Singapore.
3 (e)If no links to international classifications exist or no international standard is used, please state if there are plans to use international norms in the future.-
