However, when it comes to the sociological contribution, analysis and possible solutions to problems, a broader vision is needed. We must deal with the consequences of demographic development, with a complex and interconnected context that excludes appeasing responses. Population losses and housing vacancies cause significant socio-spatial restructuring between cities or regions, but more dramatically within larger cities. Since the mid-1990s we have observed an intensification of the processes of segregation and social polarization. In areas with low-income populations, social segregation due to social transfers continues following departures and vacancies; New types of poor districts are created and real estate becomes less profitable. Furthermore, in some areas, there are effects of selective mobility (removal of high-income families). They are reflected in the fact that poverty is becoming more and more visible in public places and that social conflicts between culturally different groups of inhabitants are increasing. This translates at least into a greater probability that segregation processes create areas with a high density of economically, socially and culturally excluded families. In this way the social balance is endangered. Significant destabilization is triggered and the weakening of the performance of such neighborhoods contributes to further disadvantages. High segregation with negative social selection leads to the abandonment of urban public space and weakens social competence and the wealth of experiences. This often results in the formation of a negative image and losses of social integration. Population loss and increased vacancies cause significant financial damage to most housing associations and cooperatives and to many private homeowners. The markets are destabilized. As regards the use of infrastructure, the problem of underutilization of real estate assets continues. Otherwise, only apartments are empty, but also nurseries, schools, public transport, doctors' offices, shops and other services are much less used, quickly posing existential problems for cities, because the facilities are no longer accessible. The contraction processes are considered quantitatively difficult to control and in their current dimension as ongoing. Anyone who wants to move away for work reasons or because the image of the residential area no longer suits them will not be able to resist without there being fundamental changes that have a reliable perspective. It is believed that a redefinition of the mission statements of urban development with decreasing population is a necessity. To this end, public litigation should take place which should focus on renewal opportunities. Fundamental political decisions are considered necessary; they could and should show the prospect of a "new quality of shrinking city". Urban renewal programs with the necessary management capacity, within which clear priorities must be established, should be developed and financed to the extent necessary. One of these is a demolition program and management (including the..
