COMPUTER OPERATIONS REQUEST #368

Subj:  Clarification of the respondent's education variable in  
       the 1975 sibling roster - selection of birth order and 
       education variables. 

       This COR was in response to a question about the creation 
       of the education variable for the respondent entered in the 
       sibling roster for the 1975 data.

     Appendix S to the codebook shows that the education variable
used for the respondent in the sibling table is not EDEQYR, but
EDYRCM. EDEQYR translates educational credentials into equivalent
years, of schooling, while EDYRCM is simply the respondent's
report of total number of years of college completed in Question
3b of the 1975 questionnaire. we added 12 to EDYRCM to obtain the
number of years of schooling. You will get exact matches when you
use BORSIB to identify the position of the respondent in the
sibling table. But note that"00" which is less than 1 year and
"88" which stands for inap, are both recorded in the sibling
table as 12 years of school. We chose to use EDYRCM, rather than
EDEQYR in the sibling tables because it is more comparable in
concept to educational attainment as ascertained in the sibling
roster.

     There are discrepancies in the tabulation of EDEQYR by the
education of the respondent as identified by BORSIB in the
sibling table, and this is to be expected. We have tabulated
EDYRCM by the education of the respondent as identified by BORSIB
in the sibling table, following the rule specified above, and we
obtained an exact match.

     We also crossed BOR (which is the respondent's birth order
among ever-born siblings) with BORSIB (the respondent's position
among currently surviving siblings), and there were discrepancies
in 10.2 percent of the cases.

     While the sibling section of the codebook does refer readers
to Appendix S (p, 309, at col 552), this warning should be
displayed more prominently in an updated version of the codebook.

1.  Locate the education of the respondent in the sibling table
using BORSIB as the key and create the variable EDBORSIB.

do if BORSIB = 1
compute EDBORSIB = CFOED1 
else if BORSIB = 2 
compute EDBORSIB = CFOED2 
else if BORSIB = 3 
compute EDBORSIB = CFOED3 
else if BORSIB = 4 
compute EDBORSIB = CFOED4 
else if BORSIB = 5 
compute EDBORSIB = CFOED5 
else if BORSIB = 6 
compute EDBORSIB = CFOED6 
else if BORSIB = 7 
compute EDBORSIB = CFOED7 
else if BORSIB = 8 
compute EDBORSIB = CFOED8 
else if BORSIB = 9 
compute EDBORSIB = CFOED9 
else if BORSIB = 10 
compute EDBORSIB = CFED10 
else if BORSIB = 11 
compute EDBORSIB = CFED11 
else 
compute EDBORSIB = 99
