CAMSIS-Venezuela

Scales for Venezuelan data (1981, 1990 and 2001) have been constructed using census microdata obtained from IPUMS-I

Data 1981 Census extract accessed via IPUMS-I

Cases 34k pairs of both-working married or cohabiting couples + + +

Occupational classification

Scales have been derived at three units of analysis:

The Venezuelan 1981 'occ' variable availabe at IPUMS-I (close to ISCO-88 3-digit)

- Coding frame from IPUMS-I at: https://international.ipums.org/international-action/variables/VE81A425#codes_section

- Text value labels in English (.do)

Units of analysis which cross-classify educational level with ISCO-88 3-digit units

- ISCO-88 cross-classified by whether or not a respondent has a universtiy degree

- Coded values = isco88 (3-digit) + 10000*(uni), where 'uni' is a 0/1 indicator for whether or not an individual has auniversity level of education, indicated by the IPUMS-I variable 'edattan' having value 4

- ISCO-88 cross-classified by whether or not a respondent has a secondary level of education

- Coded values = isco88 (3-digit) + 10000*(sec), where 'sec' is a 0/1 indicator for whether or not an individual has a secondary or higher level of education, indicated by the IPUMS-I variable 'edattan' having values of 3 or 4

Additional derivation information
Scales have been derived by using semi-automated correspondence analysis routines in Stata. These routines recode sparsely represented occupations to merge them with the largest occupations in the minor, sub-major or major group as appropriate, and applies any additionally nominated pseudo-diagonal declarations or desired records, then generates standardised scale scores for males and females. The 'details' file contained within the zip archive gives further information on the derived data, including secondary dimension scores and estimated margins of error for the respective scale scores.

The macro file used is at: make_camsis_venezuela_1981_2.do

A small number of pseudo-diagonals were defined and used in the macro, listed as: occ units / occ-by-educ units

A small number of nominated recodes were made to merge sparse occupations, listed at: occ units / occ-by-educ units

Units of analysis which cross-classify educational level with ISCO-88 3-digit units

- ISCO-88 cross-classified by whether or not a respondent has a universtiy degree

- Coded values = isco88 (3-digit) + 10000*(uni), where 'uni' is a 0/1 indicator for whether or not an individual has auniversity level of education, indicated by the IPUMS-I variable 'edattan' having value 4

- ISCO-88 cross-classified by whether or not a respondent has a secondary level of education

- Coded values = isco88 (3-digit) + 10000*(sec), where 'sec' is a 0/1 indicator for whether or not an individual has a secondary or higher level of education, indicated by the IPUMS-I variable 'edattan' having values of 3 or 4

Units of analysis which cross-classify educational level with ISCO-88 3-digit units

- ISCO-88 cross-classified by whether or not a respondent has a secondary level of education

- Coded values = isco88 (3-digit) + 10000*(sec), where 'sec' is a 0/1 indicator for whether or not an individual has a secondary or higher level of education, indicated by the IPUMS-I variable 'edattan' having values of 3 or 4

- Background: We also attempted to generate a scale which used ISCO-88 cross-classified by whether or not a respondent has a higher level education - as reported in Griffiths and Lambert 2011 - however the data we accessed did not contain substantial representation of cases coded as having higher/university levels of education so we do not use this measure in further work.
