The Scholarly Migration Database provides detailed data about the mobility of scholars. Scientists, journalists and policy analysts who are interested in the movements of published researchers can access high-quality datasets and estimates via this website. The Scholarly Migration Database is prepared and hosted at the Max Planck Institute for Demographic Research in Rostock, Germany.
The Scopus bibliometric database strives to have all the metadata about every published journal article since 1996.
We use the affiliation information and the author identifier to track movements of individual researchers from country to country.
We then aggregate the migration events to get in- out- and net-migration counts for every country.
See the DATA page for a detailed explanation of the data processing steps.
