Dimensions of Urban Social Sustainability: A Study Based on Polish Cities

This article focuses on two dimensions of social sustainability in contemporary cities: (1) social participation as a form of communication between residents and city authorities and (2) urban inclusivity. The assessment of these dimensions was conducted on a representative sample of 1863 residents from 19 Polish cities, seeking to answer the following research question: How do residents assess two key dimensions of social sustainability: social participation and urban inclusivity? The results were analyzed using descriptive statistics and non-parametric tests. The findings indicate that social participation in the studied cities is not fully developed. Respondents positively evaluate the idea of participatory budgets but are not satisfied with the cooperation between city authorities and residents, or with the possibilities for controlling local government actions. In terms of urban inclusivity, residents perceive themselves as quite open to diversity, but critically assess the city authorities’ efforts to counteract social exclusion. The research also shows that despite similar regional conditions, the social sustainability varies considerably, which highlights the importance of local policy in creating fully sustainable Smart Cities. The findings advance Smart City theory through practical social sustainability assessment and identification of improvement areas. This diagnosis provides insights for municipal authorities and offers guidance for policymakers developing legislation to foster social sustainability, strengthen civic participation, and combat urban exclusion.
