"Quantifying the international bilateral movements of migrants"
by Parsons, Christopher, Ronald Skeldon, Terrie Walmsley and Alan Winters

The economics literature increasingly recognizes the importance of migration and its ties with many other aspects of development and policy. For example the role of international remittances (Harrison et al 2003), or those immigrant-links formed between immigrants and bilateral trade flows (Gould 1994). More recently Walmsley and Winters (2005) demonstrated utilising their GMig model that lifting restrictions on the movement of natural persons would significantly increase global welfare with the majority of benefits accruing to developing countries.

It is somewhat surprising therefore that few attempts have been made to collate detailed and comparable bilateral (migration) data. A truly global perspective has never been adopted as past attempts focus upon particular regions or member states of international institutions. This work also commonly makes no distinction between those foreign born by country of birth and those recorded by their nationality despite the large disparities that often exist between the two series.

This paper attempts to rectify these shortcomings of the literature and presents two matrices for 226 by 226 countries, the first of which records the number of foreign born individuals by country of birth and the second by nationality, which, for the purposes of the paper is treated analogous to citizenship. Though countries employ a plethora of different methods for collecting and presenting this data here attempts to reconcile these methods offers as full and comparable a dataset as is currently possible, which it is hoped will provide a rich resource for future research.

In particular the database will be used to develop the GMig model, supplementing the previous version with bilateral migration data thus facilitating a comparison with the previous findings of Walmsley and Winters (2005). While ex-ante it is believed implementing the model with superior quality data should not significantly alter the overall conclusions of their paper, it is anticipated that the magnitude of their result may change.
