2. Overview (1)NS-SEC categories (2)NS-SEC derivation (3)Constructing the NS-SEC

3. The NS-SEC 1Higher managerial and professional occupations (1.1 Large employers and higher managerial) (1.2 Higher professional) 2Lower managerial and professional occupations 3Intermediate occupations 4Small employers and own account workers 5Lower supervisory and technical occupations 6Semi-routine occupations 7Routine occupations 8Never worked and long- term unemployed

4. Categories of the Operational Version of the NS-SEC

5. Collapsing the NS-SEC (1) Operational categoriesEight (Nine) ClassFive ClassThree Class L1 Employers in large establishments L2 Higher managerial occupations 1.1 Large employers and higher managerial occupations 1.2 Higher professional occupations 1 Managerial and professional occupations 1 Managerial and professional occupations L3 Higher professional occupations L4 Lower professional and higher technical occupations L5 Lower managerial occupations L6 Higher supervisory occupations 2 Lower managerial and professional occupations L7 Intermediate occupations 3 Intermediate occupations L8 Employers in small establishments L9 Own account workers 4 Small employers and own account workers 2 Intermediate occupations Analytic variables 3 Small employers and own account workers

7. The Derivation of the NS-SEC Basic SEC Positions EMPLOYERSSELF-EMPLOYEDWORKERSEMPLOYEESEXCLUDED Labour Form of employment regulation ServiceIntermediate Supervisors, lower technical semi-routine, routine Intermediate Professionals managers LargeSmall Never worked Long-term Unemployed Self-employed (1.1) (1.2,2,4) (4) (1.1,1.2,2) (3) (5,6,7) (8)(8)

8. Validation studies (a)CRITERION VALIDATION Do measures of employment relations discriminate between the categories of the NS-SEC? (b)CONSTRUCT VALIDATION How well does the NS-SEC explain variance in theoretically relevant dependent variables?

9. Summary NS-SEC is first a conceptual construction (hence NS-SEC is a schema) To operationalise the schema we need an algorithm to a detailed set of occupation- by-employment status units

10. Constructing the Derivation Matrix (1) Information required on: 1.occupation: coded to SOC2000 OUG; 2.employment status; 3.number of persons in the establishment (0, 1-24, 25+).

11. Reduced & Simplified versions of NS-SEC Reduced NS-SEC- if no information on establishment size Simplified NS-SEC-if data only on occupation

12. NS-SEC Household Class EITHER Highest Income Householder ORDominant position in labour market

13. Advantages of the NS-SEC Conceptually clear and rigorous Simple to create Flexible in use Easier to maintain Better explanatory tool
