Description

(1) This offshorability index for ISCO-08 occupational categories is based on Blinder's (2009) original index that was applied to US SOC categories. We adapt Blinder's index to the ISCO-08 system by crosswalking SOC 2010 to the ISCO-08 classification system.

(2) The Routine Task Intensity (RTI) scores used in the study were assigned to ISCO-88 4 digit categories. The RTI scores were based on calculations made and found in Owen and Johnston’s (2017) study which are available in the supplementary material found here: https://static.cambridge.org/content/id/urn:cambridge.org:id:article:S0020818317000339/resource/name/S0020818317000339sup002.zip

(3) From Round 6 of the European Social Survey, occupational categories were classified using the ISCO-08 system rather than the ISCO-88 system. To assign the RTI scores calculated by Owen and Johnston (2017), we downgraded the ISCO-08 occupational categories to their respective ISCO-88 categories. The codes for this crosswalk were provided by Thewissen and Rueda (2017) which are available in the supplementary material (file name: “Thewissen_Rueda_CPS_1_ESS.do”) found here: https://journals.sagepub.com/doi/suppl/10.1177/0010414017740600/suppl_file/CPS_publication.zip
