Social Networks and Migration

说明(申请人提供)：与社会网络和社会支持概念的链接对于推动移徙理论和研究至关重要。社会联系，以及基于这些联系结构的社会网络，影响着潜在移民是否离开，他们去哪里，以及返回的可能性。对目的地的移徙和社会网络进行了大量研究。但人们对移民来源地及其内部的联系知之甚少，很可能是因为数据要求非常严格(预期的社交网络数据，然后跟随移民到达目的地)。这项拟议的研究填补了这一空白。它使用了一个独特的、前瞻性的纵向数据集，该数据集在1994年测量了泰国东北部南荣区51个村庄的完整社交网络数据，然后跟踪了人们一段时间(到2000年)的始发地和目的地。我们提出了三个相关的分析。第一项研究考察了与原籍的社会联系对1994年居住在该村的人在2000年成为移民的可能性的影响，检验了关于获得信息和其他资源、义务和相对剥夺的含义的假设。第二个重点是回返移民。对于那些在1984年的一轮数据收集中在场但在1994年不在该村的人，与原籍的联系对移民在2000年回到该村生活的可能性有什么影响？关于回返移民的假设集中在这些联系的义务部分。第三项分析将调查1994至2000年间每年的社会关系的影响，研究短期内的移民，并检验有关1997年7月经济危机影响的假设。第三个分析基于拥有移民和非移民生活史数据的村庄的子集。

DESCRIPTION (provided by applicant): Links to concepts of social networks and social support have been crucial to advances in migration theory and research. Social ties, and the social networks based on the structure of these ties, affect whether potential migrants leave, where they go, and the likelihood of return. Substantial research has been done on migration and social networks in places of destination. But little is known about ties to and within the origin, most likely because the data requirements are so severe (prospective social network data and then following migrants to destination). The proposed research fills this gap. It uses a unique, prospective, longitudinal data set that has complete social network data at origin measured in 1994 for 51 villages in Nang Rong district, Northeast Thailand, and then follows people over time (to 2000) in origin and destinations. We propose three related analyses. The first examines the effects of social ties to the origin on the likelihood of being a migrant in 2000 among those who were resident in the village in 1994, testing hypotheses about the implications of access to information and other resources, obligations, and relative deprivation. The second focuses on return migration. For those who were present in the village in the 1984 round of data collection but absent in 1994, what are the effects of ties to the origin on the likelihood that the migrant is living back in the village in 2000? Hypotheses about return migration focus on the obligational components of these ties. The third analysis will investigate the effects of social ties year by year between 1994 and 2000 to study migration over short intervals and to test hypotheses about the effects of the economic crisis in July 1997. The third analysis is based on a subset of villages having life history data for both migrants and non-migrants.
