One type of population redistribution is discussed in this paper. It is the migration of older people between metropolitan and nonmetropolitan locations as it has occurred over three decades. Both net migration and stream migration studies documented the metropolitan-to-nonmetropolitan turnaround between 1960 and 1970, but no three-decade trends have been established and thus the trend remains in doubt. The data used in this analysis came from the census microdata files, using the 1-in-100 samples in 1960 and 1970 and the 1-in-40 sample in 1980. Only the records of persons age 60 and over were examined. This analysis documents the continuation of the turnaround in 1980 among older migrants and pictures them as forerunners of larger migration trends. It also discusses the dynamics of the trend and some of the processes that may have brought it about and maintain it.
本文讨论了一种人口再分布类型。它是老年人在大都市和非大都市地区之间的迁移，这种迁移在过去三十年中一直在发生。净迁移和流动迁移研究都记录了1960年至1970年间从大都市到非大都市的转变，但尚未确立三十年的趋势，因此这一趋势仍存疑问。本分析中使用的数据来自人口普查微观数据文件，1960年和1970年使用的是1%的样本，1980年使用的是40分之一的样本。仅对60岁及以上人群的记录进行了检查。本分析记录了1980年老年移民中这种转变的持续情况，并将他们描绘为更大规模迁移趋势的先驱。它还讨论了这一趋势的动态以及可能导致并维持这一趋势的一些过程。
