Repeat Migration in the United States: Who Moves Back and Who Moves On?
研究美国人口重复迁移现象，分析个人在特定地点积累的资本和迁移前获取的信息质量如何影响迁移决策，对理解当前迁移行为和人口空间变化有重要贡献。
Declining rates of national population growth, continuing differential levels of regional economic activity, and shifts in the migration patterns of people and jobs are characteristic empirical aspects of many developed countries.In some regions they have combined to bring about relative (and in some cases absolute) population decline of highly urbanized areas; in others they have brought about rapid metropolitan growth.The objective of the Urban Change Task in IIASA's Human Settlements and Services Area is to bring together and synthesize available empirical ant1 theoretical information on the principal determinants and consequences of such urban growth and decline.This paper focuses on the repeat moves that many people in the United States make during their lifetime.The analysis is based on the capital that individuals accumulate in a specific location and on the quality of information that migrants obtain before making their decision to move.The careful examination of why people move and the focus on migration sequences make this essay a particularly important contribution to our understanding of current patterns of migration behavior and spatial population change.
