Research on relations between services for older persons and senior migration

首先回顾了有关老年人流动的文献，重点介绍了老年人流动转移假说，然后利用日本1995-2000年的人口普查数据对老年人流动转移假说进行了验证。为了获得数据，采用了队列分析。有949个城市的人口在退休前增加，所有城市都通过传真和电话被问及老年移民计划。有效率为72.9%。研究发现：(1)老年人迁徙与一般迁徙无关。(2)老年人迁徙发生在郊区和农村市镇。(3)管理人员并不总是了解老年人迁徙的事实。(4)老年人迁徙的背景是由住宅开发、归国和新来者的介绍、医院和机构的基础以及农村新生活方式的趋势等因素构成的。本文对日本各县的老年流动与社会服务水平进行了统计分析，认为老年流动假说在日本1995-2000年是从海归流动向更高服务型流动的阶段。对于包括老年流动到社区的老年流动，美国科罗拉多州的退休社区协议是可行的。

At first, literatures regarding elderly migration are reviewed and the hypothesis of elderly mobility transition is focused.Then the hypothesis of elderly mobility transition is verified on Japanese Census data between 1995 and 2000. For getting the data, the cohort analysis is applied. There are 949 municipalities, whom population was increased at pre-retirement stage.All municipalities were asked with fax and telephone on programs for elderly emigration. Rate of response was 72.9%. Findings are as below:(1)The elderly migration is not co-related with the general migration.(2)The elderly migration is occurred in suburban municipalities and rural municipalities.(3)Administrators did not always aware of the facts of elderly migration.(4)The background of the elderly migration are constructed with many causes such as residential development, introduction for returnees and new-comers, foundation of hospitals and institutions, and trend of the new way of rural life.Also, statistical analysis between the elderly migration and the level of social services is conducted on prefectures.The hypothesis of elderly migration is certified in Japan 1995-2000 as the stage from the returnee mobility to the higher service oriented one.For including elderly migrants to a community, agreement of a retirement community in Colorado, U.S. is available.
