MIG 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, but it is also the most volatile and difficult to forecast, thus requiring innovative data and methods to circumvent the difficulty in estimating and predicting future migration. The novel approaches employed by the MIG Group allows for the production of comprehensive estimates of internal and international migration and its drivers at the global, national, and sub-national level. The group’s research provides comprehensive insight into the social, economic, and environmental drivers of migration considering changes and interactions between the drivers. In particular, the group focuses on investigating the direct and indirect pathways through which environmental changes influence internal and international migration and how the effects vary across geographical locations and population subgroups.

Fact Sheet Climate Change and Demography

The reciprocal relationships between human populations and the environment becomes increasingly important in the light of climate change. Researchers from IIASA and Wittgenstein Centre published the Fact Sheet Climate Change and Demography, providing information for policy makers and scientists about some key areas where demography can contribute to climate research.

Experience of climate extremes increase Green voting in Europe

What role do experiences with climate change and extreme events play in shaping environmental attitudes and to what extent can they explain the recent rise in environmental concerns and willingness to vote for Green parties across Europe? IIASA researchers set out to investigate these and related issues in a new study just published in Nature Climate Change.
