The importance of modelling migration flows to understand demographic change is described in this presentation. Migration affects population levels in both the sending and receiving areas, as well as age-sex compositions and subsequent demographic processes, such as fertility, ageing, and further internal or international migration. Reliable data on migration flows that allow us to study these effects, on the other hand, are often not available. In this presentation, issues concerning the availability of migration flow data are presented, followed by a description for how indirect methods for estimating migration flows can be combined with spatial population models to better understand the long-term effects of migration on population change.

About the Speaker:

James Raymer is a Professor of Demography at the Australian National University. His research focuses on developing methods and frameworks to study demographic processes. He is especially interested in studying migration in instances where data are inadequate or missing, and has led many interdisciplinary and international research collaborations on topics ranging from estimation of migration flows to population forecasting. His recent research has involved estimating international migration in the Asia Pacific region and small area demographic analyses for Australia. For the past six years, he has been an active participant in the United Nations’ Expert Group on Migration Statistics.
