Are there cross-walk that map the 1980 and 1992 industry classifications used in the BHPS?
I need to create a variable about the industry in which respondents work that is consistent for the 18 waves of the BHPS. The information is contained in two main variables: jbsic, which uses the UK SIC 1980 classification and is available until 2001 and jbsic92 which uses the UK SIC 1992 classification and is available from 2001 onwards. I would need a cross-walk to map each category of one of the variables to the closest category in the other variable.
I'm sure many users have had similar problems. I would be grateful if you could indicate how to do this.

to our knowledge there is no exact mapping of SIC 1980 to SIC 1992. In some waves of the BHPS responses were coded to both coding frames (in waves 4, 7 and 11) so it may be possible to create a mapping from that, or at least to check consistency with mappings suggested by others.
The website http://www2.warwick.ac.uk/fac/soc/economics/staff/jcsmith/sicmapping/resources/direct/ provides useful links to SIC mappings - they are mainly based on the LFS and code to 1- or 2-digit condensed versions of SIC.
Hope this helps,
