I have a problem with SIC80 codes in GHS rounds before
1993 (variables sicr, sicr1, sicr2 and the like). Now I do have a table of
SIC80 codes that run (not successively) from 010 to 990, but variables like
sicr (sicr1, sicr2, etc.) in GHS (see, e.g. the round for 1989/90) contain
values from 500 to 780. It looks like SIC80 coding was just squeezed into
a successive coding in GHS. So I was wondering if you could help me with getting
a conversion table for those codes. Also, it seems like for the rounds before
1980 when SIC68 was used, the information on detailed industry break-down
was left out of GHS, i.e. the only variables that describe industry (like
"indust" in round for 1979) contain a coding of general branches
(construction, distribution, etc.) but not the original SIC68 coding. So,
I was wondering if the files with original SIC68 coding are in principle available.
