Migration information infrastructures: power, control and responsibility at a new frontier of migration research

The nature and production of migration statistics are in flux. State bureaucracies are no longer the primary source of migration data. Instead, there are a myriad unofficial data sources and processing collaborations which produce migration and mobility data as a by-product of both commercial and governmental processes. This has implications both for international processes of migration assessment and control, and for states’ domestic policies with respect to migrants. This paper brings together migration studies with Science and Technology Studies (STS) literature to take stock of these new data sources’ theoretical and empirical implications for both migrants and the links between migration and broader social processes. We identify migration information infrastructures: configurations of data assemblages which involve private and public sector actors, where data originally collected for one purpose (billing customers, sharing social information, sensing environmental change) become repurposed as migration statistics. We explore the implications of such migration information infrastructures for migration researchers: what are the entanglements that such infrastructures bring with them, and what do they mean for the ethics and practicalities of doing migration research?
