My article "Visualizing the Regionalized Structure of Mobility between Countries Worldwide" is now published open access in Socius's innovative Visualizations series. Here, geographic mapping, algorithm-based community detection, network visualization, and conventional line plots are combined to display the network structure of more than two billion estimated trips between countries worldwide in 2016, together with information about the (non)evolution of this structure over time. The graph reveals that transnational mobility is highly regionalized: 80 percent of all human movements between countries occur within world regions. Despite strong increases in the absolute amount of transnational mobility, this share remains extremely stable between 2011 and 2016. The community detection algorithm reveals six mobility clusters that clearly correspond to world regions: Africa, Asia and Oceania, the Americas, Eurasia, Europe, and the Middle East. This stable, regionalized structure suggests that a fully globalized “world society” is unlikely to emerge, as social ties remain parochial, even in the transnational sphere.

Together with Nils Witte and Jean Philippe Décieux, I am co-organzing an ad-hoc group at this year's conference of the German Sociological Association, which will take place from September 14-18, 2020 at TU Berlin. The ad-hoc group is titled Dynamiken und Folgen transnationaler Migration als Herausforderung für die empirische Migrationsforschung. We are looking for additional presenters. If you are interested, please have a look at the call (in German). We look forward to receiving your proposal!
