The interdisciplinary field of migration studies is broadly interested in the causes, patterns, and consequences of migration. Much of this work, united under the umbrella of the “new economics of migration” research program, argues that personal networks within and across households drive a wide variety of migration-related actions. Findings from this micro-level research have been extremely valuable, but it has struggled to develop generalizable lessons and aggregate into macro-level and meso-level insights. In addition, at group, region, and country levels, existing work is often limited by only considering migration total inflows and/or total outflows. This focus misses many critical features of migration. Using location networks, network measures such as preferential attachment, preferential disattachment, transitivity, betweenness centrality, and homophily provide valuable information about migration cascades and transit migration. Some insights from migration research tidily aggregate from personal networks up to location networks, whereas other insights uniquely originate from examining location networks.
