It is often argued that there is a paucity of data on migration. While this is broadly true, there is in fact an abundance of data being produced which could inform migration policy but which has yet to be fully utilized.
Vast amounts of data are generated through the use of mobile phones, internet-based platforms and other digital devices in real time, at very little cost. These “digital crumbs” can offer important insights into societal phenomena, including migration, as shown by an increasing number of studies and initiatives.
