The MIG research group focuses on applying advanced data collection and estimation methods to quantify and better understand the trends, patterns, drivers, and consequences of different types of migration considering its interactions with the social, economic, and environmental dimensions of sustainable development.

Migration is a key demographic component underlying population change. As a multifaceted process, it is influenced by various factors such as economic opportunities, social and political drivers, environmental changes, and conflicts. Due to its high volatility and complexity, migration is difficult to assess and forecast, thus requiring a combination of data sources and methods. The MIG research group employs innovative approaches to provide comprehensive estimates of internal and international migration and its underlying factors at global, national, and sub-national levels. A particular focus of the research group is exploring how climatic changes and environmental factors directly and indirectly influence migration, and how these effects differ across geographical locations and population subgroups. In addition, the research group offers valuable insights into the interconnections between sustainability, human development, and well-being, highlighting their relevance for migration processes worldwide.
