"Over the last decades the societal and physical environments, including all types of technologies, have changed at increasing speed. For elderly people, in particular, it is difficult to keep pace with these developments because of several reasons: The prevalence of sensory loss, of declining motor performance, or of chronic illness is growing with advancing years. Unfavourable environmental and technological conditions are by this of more serious consequences and make an autonomous living inside and outside the home more difficult. Older people are largely cut off from modernisation processes which are conveyed by gainful labour. Therefore, the increasing mechanisation of public spaces and services by new information and communication technologies can lead to massive problems for them. As a consequence, the relationship of elderly people to their environments is of increasing importance because of individual and societal reasons. Before this background, this symposium includes several contributions of researchers of The German Center for Research on Aging. This Center, and in particular its Department for Social and Environmental Gerontology, has made the investigation into the issue of person_environment relations in old age its business. The primary aim of the symposium is thus to sensitise for this topic as well as to present a bunch of empirical results of according research projects done at the Centre. Also, the plan is to discuss these results with external discussants and interested participants in the conference. In the introductory paper presented by Hans_Werner Wahl, an general overview on recent research regarding the topic of person_environment relations in the old age will be given. Also, potential practical implications which probably may change the everyday life of the today's and tomorrow's elderly are highlighted. The second paper presented by Frank Oswald starts from the insight that housing research often put too much emphasis on the standard of objective housing conditions and the role of home modifications for older people. Little attention has been paid, however, to the subjective experience of home in old age and-to processes of "place attachment". The third paper by Heidrun Mollenkopf points to the fact that mobility is the decisive link between the individual and his or her social and built environment. To approach this issue, a report of the results of an international research project comparing the mobility and activity patterns of 55 years old and older men and women in three European countries with diverging cultural, geographical and structural backgrounds (Finland. Germany and Italy) will be given. A fourth contribution provided by Karin Gang will focus on one farreaching and mostly self-chosen change of the environment that is, relocation within private household living. As main part of this paper, motivations of move are analysed according to (1) function (push versus pull factors), (2) content (person, environment, other), and (3) basic (e.g., health) vs. higherorder needs (e.g., privacy). Finally, the presentation of Minnemann, Schmitt and Sperling will cover a broader life span regarding subjective and objective housing aspects. In particular. the German Interdisciplinary Longitudinal Study on Adult Development and Aging offers the opportunity to compare housing issues of a cohort of elderly born in 1930-32 with a cohort of middle-aged persons born in 1950-52."
