The demographic changes currently being observed, including the growing proportion of older people in the population, necessitate the implementation of spatial planning policies aimed at ensuring the accessibility and functionality of public spaces, taking into account the needs of this demographic group. The World Health Organization’s (WHO) recommendations on creating cities that are friendly to ageing societies emphasise the need to take long-term demographic processes into account in spatial planning. The current approach, focused on development and meeting the current demand for housing, should be complemented by consideration of future changes in population size, migration and age structure. The projected population decline and increase in the proportion of older people imply the need to redefine the directions of spatial development and to adapt infrastructure and urban functions to the new circumstances. This paper focuses on a synthesis of existing research on spatial planning with regard to the needs of older people, as well as on an analysis of national legal regulations relating to spatial planning in this area. The issues addressed are of significant importance in the context of projected demographic changes and the need to shape spaces that promote social integration and improve the quality of life for older people. The findings of the article point to the need to refine planning tools and strengthen legal provisions in the area under analysis.
