License to Work 3 Data

Comparison Dataset

Download the comparison dataset used for the study. The dataset provides revised data for all three editions of License to Work. Data for the second and third editions are comparable across all 102 occupations. However, as indicated in the dataset, only 45 occupations are comparable across all three editions due to systematic differences in data collection methodology between the first and second editions. 1 Data for the third edition were collected between February 2020 and March 2022. For other details on data collection, please see Methods, Appendix A and Appendix B.


Download corrections to the comparison dataset. The download contains only corrected data, not all data for an occupation. The first tab provides the corrections, while the second provides explanations for those corrections. If we become aware of further necessary corrections, we will post new versions of this download.
