Data |
2002 Census, accessed via IPUMS-International, www.ipums.org |
Cases
|
Analysis was standardised on the population of adults with jobs within the 2002 census (840971 individuals). CAMSIS scale derivations performed on sub-population of both-working heterosexual cohabiting couples (221950 couples). |
| Occupational classification: | International Standard Classification of Occupations 1988 (ISCO-88) (details). Note: ISCO-88 occupation 110 (armed forces) is not represented in the scale construction process and is given a missing value for CAMSIS scale score in the index files above. Additional scales (version 2) for the 2002 unit, microclass units, and occupation-by-education combinations are available from the US CAMSIS 'SONOCS' versions (as described in Griffiths and Lambert 2011) |
Status in employment: |
Three category scheme (variable 'empst3'): 0 - Unknown Employment Status 1 - Self-employed with employees [in ISCO88 major group 1] 2 - Self-employed without employees (own account) 3 - Employee (See http://www.geode.stir.ac.uk/ougs.html#empst3 ). Note: Derived from the IPUMS unharmonised variable 'classwkd'. For the Romanian IPUMS data, the category 1 (self-employed with employees) is only represented in ISCO-88 major group 1. For practical purposes, we recommend that the cateogry 2 be used for self-employed with employees in other ISCO-88 major groups. |
| Author/construction notes: | Version 1 scale generated December 2008 by Paul Lambert, Univ. Stirling, using Stata correspondence analysis routines. The Version 2 scale, released in May 2011, uses less occupational detail (occupations only, disregarding employment status), but does have the attraction of enabling comparisons between ISCO and microclass units. |
