timeliness, costs…
WHY (BETTER) MIGRATION DATA?
To (better):
- balance the public debate on migration;
- understand migration;
- evidence-inform migration policies.

CONCLUSIONS
Data can help balance the public debate around an often
misconceived theme such as migration
Policy advice and knowledge management for migration require
full awareness of data opportunities and limitations
Data timeliness, disaggregation by time, space and attributes can
be addressed through research and alternative methods
