Patterns of internal migration of highly qualified people in Mexico. A characterization through complex network visualization and social network analysis.

Many real, social, technological, biological and information systems can be described as complex networks, however, few works contemplate migration from the perspective of complex networks such as that by Askar and House (2010) that study multi-scale mobility patterns in the United Kingdom and the one by maier and Vyborny (2005) that analyze internal migration in the USA. In general, migration studies are focused in people, while other studies focus on places. The former requires very detailed data while the latter are based on aggregated data. In this case we will follow this last idea, in such a way that the motivations to change place of residence will be left out. Migration flows will be taken as a given and the resulting patterns of those flows will be the object of this study. In Mexico, census data is collected every 10 years, 2010 being the most recent and not up until recently there exist tools and capacity to visualize and model internal migration at the municipal level. While in general municipalities have been characterized by their net migration, hiding patterns that link origins and destinations, this study will help characterize the migration patterns.
