Abstract
This study constructs the population migration networks among economic areas in the United States for every consecutive year from 1990 to 2011, and examines their structural properties and population migration dynamics. Various aspects of the structural properties of the networks are explored, including the connectivity, clustering, assortativity and centrality. It was found that these structural properties are mediated by migration dynamics and inter‐area distance, and the patterns of varying structural properties across areas of different connectivity reveal the hub‐and‐spoke structure of the networks. It is evident that there exists tremendous complexity in migration connectivity and dynamics in the US internal migration system. Este estudio construye las redes de migración de población entre áreas económicas en los Estados Unidos para cada año consecutivo desde 1990 a 2011, y examina sus propiedades estructurales y la dinámica de migración de la población. Se exploran varios aspectos de las propiedades estructurales de las redes, como la conectividad, la conglomeración, la asortatividad y la centralidad. Se encontró que estas propiedades estructurales están influidas por las dinámicas de migración y la distancia entre áreas, y que los patrones de diferentes propiedades estructurales entre áreas de diferente conectividad revelan la estructura de eje central y radios de las redes. Se pone de manifiesto que existe una tremenda complejidad en la conectividad y dinámica migratoria en el sistema migratorio interno de los Estados Unidos. 本稿では、1990年から2011年までの毎年の米国の経済領域間の人口移動ネットワークを構築し、それぞれの構造的特性と人口移動のダイナミクスを検討する。コネクティビティ、クラスタリング、同類度(assortativity)、中心性など、ネットワークの構造的特性の様々な側面を検討する。これらの構造的特性は移動ダイナミクスと地域間の距離が媒介しており、コネクティビティの異なる地域における様々な構造的特性のパターンから、ネットワークがハブアンドスポーク型の構造であることがわかる。米国国内の人口移動システムにおける移動のコネクティビティとダイナミクスは非常に複雑であることは明らかである。
