Six, five and three class models
The 10 class model may be collapsed to 6, 5 or 3 classes. In the six class model, classes 1 and 2 are combined to form class 1 ‘the salariat’; classes 3 and 6 combine into an ‘intermediate employee’ class 2; classes 4 and 5 become a single class 3 of ‘small employers and self-employed’; class 7 becomes class 4; class 8 becomes class 5; class 9 becomes class 6.
To make the 5 class model, classes 5 and 6 in the six class model are combined into a single class of ‘lower technical and routine occupations’.
In relation to the ten class model, the three class model combines classes 1 and 2=salariat; 3, 4, 5 and 6=intermediate; 7, 8 and 9=working class. Class 10 may be added as an additional in any of the models, if desired. However, note that Class 10 is NOT a dump code for cases which cannot otherwise be classified.
When datasets have certain information missing, analysts may want to consider collapsing ESeC into five or three class versions. The implications of doing this are examined in more detail in (see Appendix 2).
