Due to the processes of re-urbanization metropolitan areas don ́t seem to beaffected by the consequences of demographic change. Also the city of Hamburg ischaracterized by a low-growing population till 2025. But a small-scale analysis ofthe demographic and social change shows a differentiated spatial developmentwithin the city. On the one hand the inner-urban districts are affected by theimmigration of young in-movers. On the other hand the lower and middle classsuburban districts are characterized by the processes of aging and poverty. Theconsequence is that more and more poor elderly have to organize their everyday lifein these monofunctional districts.A study about the action spaces in different urban contexts shows that there is anage impact on action spaces in peripheral areas. While the action spaces ofemployed persons are oriented to the inner-city, the mobility of the elderly isconcentrated on their neighbourhood. This concentration increases by poverty andsocial isolation as a result of spatial effects of the monofunctional residential area.So there is a spatial impact on social disadvantage especially of the poor elderly inthese suburban districts.
