Data traces and the inevitable visibility of irregular migration
Author
Description (eng)
Key points
• Irregular migrants, like all people, leave behind data traces – through surveys to digital
activity and use of public services. These traces can indirectly signal their presence, even
when their legal status remains unknown or unrecorded.
• This chapter explores how metadata and alternative data sources, such as social media,
mobility records, and mortality registers can complement traditional statistics and offer new
ways to estimate irregular migration.
• Pilot studies from the MIrreM project show that while these approaches are limited and
ethically complex, they can be adapted and combined to improve understanding of irregular
migrants, including their presence, behaviours and needs.
