Litwak and Longino (1987) proposed a life course typology of elderly migration in which the second type of move is associated with the development of chronic disabilities that make it difficult to perform everyday household tasks. We examined this intermediate type of move, classified between "amenity moves" in early retirement and "institutional" moves in late old age, a type of migration that had not been verified in existing research. Using data from the 1984 and 1986 waves of the Longitudinal Study of Aging by the National Center for Health Statistics, we tested the proposition that the proportion of moves increases with higher levels of instrumental functional disability over time. The probabilities generated by our model have an impressive range as predicted by Litwak and Longino in the second move portion of their model of retirement migration.
利特瓦克和朗伊诺（1987年）提出了一种老年人迁移的生命历程类型学，其中第二种迁移类型与慢性残疾的发展相关，这些慢性残疾使得日常家务难以完成。我们研究了这种介于提前退休时的“便利迁移”和高龄时的“机构迁移”之间的中间类型迁移，这是一种在现有研究中尚未得到验证的迁移类型。利用国家卫生统计中心1984年和1986年老龄化纵向研究的数据，我们检验了随着时间推移，工具性功能残疾程度越高迁移比例越高这一命题。正如利特瓦克和朗伊诺在其退休迁移模型的第二迁移部分所预测的那样，我们模型生成的概率范围令人印象深刻。
