"The
full version of NSSEC model has 17 main categories and is collapsible down to
three categories. Only the three-category version is intended to represent any
form of hierarchy. The version intended for most users (the analytic version)
has eight categories:
1. Higher managerial and professional
occupations
2. Lower managerial and professional
occupations
3. Intermediate occupations (clerical,
sales, service)
4. Small employers and own account workers
5. Lower supervisory and technical
occupations
6. Semi-routine occupations
7. Routine occupations
8. Never worked and long-term unemployed
The
three-category version is reduced to following categories:
1. Higher occupations
2. Intermediate occupations
3. Low occupations"
