Editorial introduction: Re-making migration theory

In this editorial introduction to the special issue, we first make a series of key points about the importance of migration in today's globalised world and about the intersectionality of migration processes, which should never be studied in isolation from the various social, economic, and political phenomena within which they are embedded. The paper also draws attention to the increasing diversity of migration, which poses a challenge to ongoing attempts at new theorisation. Within geography, we note that the traditional concerns of population geographers to map and model migration have been broadened by ‘turns’ towards cultural and post-modern frameworks for understanding the nature of migration. In the final part of the paper, we summarise the six papers that follow, highlighting the unique contribution that each makes to our overall agenda of ‘remaking migration theory’ from a geographic perspective.
