   Abstract The Internet has revolutionized our economies, societies, and everyday lives. Many social phenomena are no longer the same as they were in the pre‐Internet era: they have been “Internetized.” We define theInternetizationof international migration, and we investigate it by exploring the links between the Internet and migration outcomes all along the migration path, from migration intentions to actual migration. Our analyses leverage a number of sources, both at the micro‐ and the macro‐level, including the Gallup World Poll, the Arab Barometer, data from the International Telecommunication Union, the Italian population register, and unique register data from a migrant reception center in Southern Italy. We also distinguish betweeneconomicmigrants—those who leave their country of origin with the aim of seeking better economic opportunities elsewhere—andpoliticalmigrants—those who are forced to leave their countries of origin for political or conflict‐related reasons. Our findings point to a consistently positive relationship between the diffusion of the Internet, migration intentions, and migration behaviors, supporting the idea that the Internet is not necessarily a driving force of migrationper se, but rather an enabling “supportive agent.” These associations are particularly relevant for economic migrants, at least for migration intentions. Further analyses underscore the importance of the Internet in providing a key informational channel which helps to define clearer migration trajectories.

3. A Multiscalar Consideration of the Athabascan Migration

   https://doi.org/10.1017/aaq.2020.34  

   Doering, Briana N.; Esdale, Julie A.; Reuther, Joshua D.; Catenacci, Senna D. (July 2020, American Antiquity)

   Después de vivir miles de años en el sub-árctico, evidencia lingüística y genética sugiere que hace aproximadamente 1.000 años, los Atabascanos del Norte migraban al sur oeste de los Estados Unidos. Antropólogos han surgido que esta migración, y varias transiciones conductuales in situ asociadas, fueron causados por una erupción volcánica que diezmó manadas de caribú. Sin embargo, después de esta erupción, parece que populaciones regionales se aumentó al mismo tiempo que esta transición, un cambio demográfico que pudo haber llevado un aumento en la territorialidad, la demanda de recursos, y la especialización económica. Basándose en las síntesis existentes de las dinámicas culturales en la región, analices de materiales excavados, y los paisajes de Alaska y el Yukón, esta investigación muestra que la transición Atabascana representó un cambio hacia una especialización en la recolección de salmón y la caza del caribú. Este cambio estaba asociado con un aumento general en la amplitud de la dieta, indicando una transición conductual que está más coherente con un cambio demográfico gradual. Además, esta transición conductual ya hubiera comenzado antes que la erupción volcánica en 1150 cal BP, lo cual sugiere que la inmigración al suroeste era causada por presión demográfica y no la erupción volcánica. En suma, esta investigación elabora las dinámicas complejas de resiliencia y adaptación en grupos cazadores-recolectores y proporciona un modelo comprobable para explicar otras migraciones prehistóricas.

5. Migration and the Value of Social Networks

   Abstract How do social networks influence the decision to migrate? Prior work suggests two distinct mechanisms that have historically been difficult to differentiate: as a conduit of information, and as a source of social and economic support. We disentangle these mechanisms using a massive “digital trace” dataset that allows us to observe the migration decisions made by millions of individuals over several years, as well as the complete social network of each person in the months before and after migration. These data allow us to establish a new set of stylized facts about the relationship between social networks and migration. Our main analysis indicates that the average migrant derives more social capital from “interconnected” networks that provide social support than from “extensive” networks that efficiently transmit information.
