Geographical networks of international migration

Community Evolution in International Migration Top1 Networks

Focusing on each country's topmost destination/origin migration relation with other countries, this study builds top1 destination networks and top1 origin networks in order to understand their skeletal construction and community dynamics. Each top1 network covers approximately 50% of the complete migrant network stock for each decade between 1960 and 2000. We investigate the community structure...

Immunization of Geographical Networks

We numerically investigate the epidemic spread phenomena and efficient immunization strategies on complex networks embedded in geometry. It is assumed that there exists an unavoidable time delay (we call it the detection time) between the actual infection and the beginning of immunization, and we implement two different immunization strategies: one is based on topological connection neighbors (...

Migrant networks and international migration: testing weak ties.

This article examines the role of migrant social networks in international migration and extends prior research by testing the strength of tie theory, decomposing networks by sources and resources, and disentangling network effects from complementary explanations. Nearly all previous empirical research has ignored friendship ties and has largely neglected extended-family ties. Using longitudina...

Methodological pathways to kinship networks and international return migration

Although international migration has received significant attention in the literature, this is usually in respect of development and remittances. Methodological issues on the subject are very scarce more so relative to the interface of kinship and international return migration. Yet methodological issues remain crucial to useful understanding of the processes and dynamics of the problem. This a...
