This set of crosswalks includes a full step-by-step mapping of the O*NET data, already translated to ISCO, to 4-digit KZiS 95, 02, 04 and 10 coding (used, e.g., for the Polish LFS data – BAEL).
The .zip package contains:
- Stata .dta files with crosswalks for the ISCO-88 and KZiS 04, ISCO-08 and KZiS 10 as well as between consecutive editions of KZiS (95, 02, 04, 10).
- Stata do-file recoding the ISCO-level data, step-by-step, into the KZiS classifications.
Running the do-file should be preceded by applying the ONET-SOC to ISCO crosswalks. The task item selection and bits of the Stata code were based on the work of David Autor and Daron Acemoglu
