CSDE Affiliate Zack Almquist and Regional Affiliate Jasmin Ha with colleagues Guy Abel and Jack Dewaard have just published ‘The Form and Evolution of International Migrant Networks, 1995-2015’ in Population, Space, and Place. They draw upon research techniques on community detection methods to introduce and apply the Information Theoretic Community Detection Algorithm for identifying and studying the geographic boundaries of migration networks. Using a new set of estimates of country-to-country migration flows every 5 years from 1990 to 1995 to 2010-2015, the authors trace the form and evolution of international migration networks over the past 25 years. Consistent with the concept of dynamic stability, they show that the number, size and internal country compositions of international migration networks have been remarkably stable over time; however, they also document many short- term fluctuations. They conclude by reflecting on the spirit of their work in this paper, which is to promote consensus around tools and best practices for identifying and studying international migration networks.
