目的本研究探讨了过去国际和区域间移民流动对区域老年人口增长和分布格局的影响。方法作者使用1960年，1970年，1980年和1990年人口普查数据和多区域人口模型，分析区域老年人口增长率，年龄构成，和空间分布随着时间的推移。结果。过去的老年人区域间迁移模式表现出相当大的稳定性，并在塑造区域老年人口地理的贡献小于就地老龄化。此外，移民对老年受抚养人比率的影响也很小。对1950年至1990年期间老年人口变化的重建表明，这些变化背后的驱动力是原地净老龄化，而不是净移徙。最后，对移民可能对人口年轻化产生的影响的分析表明，尽管移民的影响有助于降低老年人与工人的受抚养人比率，但过去几十年的水平不足以抵消人口老龄化的更强的抵消影响。
ObjectivesThis research examined the impacts of past international and interregional migration flows on regional elderly population growth and distribution patterns.MethodsThe authors used 1960, 1970, 1980, and 1990 Census data and multiregional demographic models to analyze changes in the sources of regional elderly population growth rates, age compositions, and spatial distributions over time.Results.Past elderly interregional migration patterns have exhibited considerable stability and have contributed less than aging-in-place in shaping regional elderly population geographies. Also the effects of immigration on elderly dependency ratios have been very modest.Discussion.Little evidence exists of any significant breaks with past trends in internal elderly migration patterns. Reconstruction of elderly population changes between 1950 and 1990 reveals that the driving force behind the changes was net aging-in-place and not net migration. Finally, analysis of the possible population rejuvenating effects of immigration suggests that although its impact has contributed to lower elderly-to-worker dependency ratios, its level over the past decades has been insufficient to counteract the much stronger countervailing impact of population aging.
