Human migration as a complex network: appropriate abstraction, and the feasibility of Network Science tools

The number of Network Science studies has risen significantly in recent two decades. Various real phenomena are increasingly analyzed as complex networks. Human migration was seldom analyzed, however, in line with global circumstances, the number of migration-as-network applications has recently grown as well. Those new migration-as-network studies are hands-on implementations of elementary measures and models. Assessments on the right kind of network abstraction of human migration, as well as the feasibility and interpretability of measures on the phenomenon, have not yet been offered. We investigate these aspects, assessing the congruence of network tools used for analyzing migration, and their informative potential for the policy and decision-making domain.
