Mayda’s index addresses migration policies in 14 OECD countries (Australia, Canada, Denmark, France, Germany, Japan, Luxembourg, Norway, Netherlands, Sweden, Swizerland, United Kingdom, United States) between 1980 and 1995.
Rather than addressing the overall policy situation for each year, the index focuses on changes in destination countries’ migration policies. The index increases by one if in that year the destination country’s immigration policy became less restrictive, decreases by one if it became more restrictive, and zero if there was no change
Based on paper documents, the authors addressed the main characteristics of the migration policies of the destination countries in the sample and the timing (after 1980) of changes in their legislations. A dataset of destination countries’ migration policy changes, between 1980 and 1995, was constructed on the basis of the information in this appendix and used in the empirical analysis
