Multiple migrations: Quantitative data approach
MultiData is a research project which aims to provide a fine-tuned picture of international movements, focusing on multiple migrations (involving people who lived in two or more countries outside of their country of origin). MultiData will provide evidence on multiple migrations using a quantitative approach. To do so, the project will utilise two kinds of quantitative datasets. First, the evidence from social surveys will be used to examine the volume of multiple migrations and their geographies. The social survey data will also allow studying to what extent multiple migrants differ from other migrants, that is, do multiple migrants possess more or fewer resources than other migrants? What is more, while traditional data sources, such as registers and surveys, shed light on some aspects of multiple migrations, there are new sources of data, which hold a potential to tell us a more comprehensive story about how the multiple migrants move between various places across time. The project will use big data on academics and footballers, to map the trajectories of international movement, return and settlement among the two professional groups. However, use of various data sources does not remain without challenges, and this is also a task for the MultiData, to assess these different data sources and to what extent various data can help us to understand the multiple migrations.
The project will be implemented in cooperation with scientists from Austria and France. The results of the MultiData project will be described in five journal articles regarding multiple migrations and migration research using quantitative methods. The project team will also present the project results at international conferences. In addition to academic publications, MultiData will provide material for public debates on migration, leading to a more diverse and realistic understanding of migration.
