Comparative study on population decline, restructuration of housing stock and housing markets in East-Germany - CityComparison

Many cities in East Germany are continuously facing the long-term task to adapt their housing stock to a decreasing housing demand. Information about demographic and housing market developments in the cities are necessary for user-oriented, ecological restructuration of the housing stock and in order to set priorities in urban regeneration. An earlier IOER-investigation of demographic change and its consequences for the urban infrastructure for the cases of 5 medium-sized towns in Saxonia and Saxonia-Anhalt in the year 2006/2007 made clear, that detailed knowledge of their past housing stock development is missing in many cities. Substantial factors of influence like annual market entry- and exit-figures for flats and also vacancy rates are often unknown. The planned work will contribute to close existing knowledge gaps.

Objective is work to determine the changes of the housing stock and residential vacancy in the cities in East Germany on the basis of detailed statistical and an analysis in order to detect structural determinants of urban housing market development. The investigation comprises the period of 1995 to 2007. It is to examine whether the urban residential vacancy can sufficiently well be determined with data from official housing stock and population statistics and whether similarities and shared development characteristics between the different cities can be identified. Apart from scientific results and the development of methodical basic knowledge the results will also form an informal basis to support practical measures in the context of the restructuration of the housing stock in the East German cities. The addressees of the results are science, politics on different levels and city administrations. The results of the project will contribute to the current debate on shrinking cities. For the city administrations a higher transparency of their problem situation might be achieved. At the same time the possibilities for comparison and exchange of experience with other cities increase.
