I want to use four digit ISCO 88 codes in Understanding Society for current job and last job. Although these variables (both 3 digit and 4 digit versions) appear in the data documentation, only condensed (3-digit) versions are available in the data. I wanted to ask whether 4 digit versions are available for Understanding Society?
P.S. I see that the 4 digit versions are publicly available in the BHPS data.
