The paper describes the creation of the Greater Paris metropolitan area (Métropole du Grand Paris, MGP), with special emphasis on the changes and challenges related to the implementation of the housing policy at the metropolitan level. MGP is an inter-municipal cooperation structure with its own budget and special status. It embraces Paris, 123 municipalities located in the neighbouring departments, and fie external municipalities. MGP will take the responsibilities in the field of: management of resources to support social housing, renovation of housing, elimination of low-quality buildings. The implementation of the housing policy at the metropolitan level is associated with a number of challenges mainly in terms of consolidation of activities undertaken by the institutions of social housing, reservation of land for social housing investments, increase in the amount of new housing, including attempts for their more even distribution at the metropolitan scale. In addition, a set of new challenges appeared due to the changing socio-demographic structure of households, which in turn require innovative architectural solutions.
The article presents a synthetic assessment of the diversity of the housing situation in Polish communes in the context of ongoing demographic changes. In addition, it presents an original method of typological research combining measures of the housing and demographic situation for all 2,477 communes in Poland as at the end of 2021. The scope of the study covered the years 2011–2021. The article identified that both functional urban areas and coastal municipalities have their own specificity in terms of housing and demographic situation, to a lesser extent this phenomenon affects mountain municipalities. It was also pointed out that the lack of a place-based policy in the National Housing Program makes it difficult to shape the national housing policy in a manner adapted to local and regional conditions.
