  version 1.0; author: Paul Lambert; released on: 21 December 2008 version 2.0; author: Paul Lambert and David Griffiths; released on: 23 May 2011
  Version 1 information
2002 Census, accessed via IPUMS-International,




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 ).

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.
