What the World Migration Report counts when people cross borders
The IOM publication brings together migration data and research on how mobility changes.
The International Organization for Migration's World Migration Report brings together statistics and analysis on people moving between countries. It reviews global patterns and puts them alongside changes in regions and individual countries.
A stock counts people living outside their country of birth or citizenship at a point in time, depending on the source. A flow tracks movements during a period. Knowing which measure a report uses helps readers understand why a change in departures can look different from a change in the size of a settled community.
