Assessing the Social Carrying Capacity of Urban Tourism: Residents’ and Professionals’ Perceptions in the Municipality of Athens

The rapid tourism development in the Municipality of Athens significantly impacts both the local economy and the daily lives of its residents. This study investigates the Social Carrying Capacity (SCC) of Athens by exploring the perceptions, experiences, and attitudes of local citizens and professionals towards the tourism phenomenon. A primary quantitative study was conducted between July and October 2024, utilising a structured online questionnaire based on a stratified random sampling method across the Municipal Communities of Athens, yielding 787 valid responses. The findings reveal a dichotomy in public perception: while the majority recognises the positive economic contributions of tourism—particularly in the catering and hospitality sectors—significant concerns are raised regarding negative socio-environmental impacts. The most severe consequence identified is the surge in housing costs and rent prices, predominantly driven by short-term rentals, followed by increased pressure on public infrastructure, cleanliness, and traffic congestion. Despite these challenges, a considerable portion of the respondents maintains a generally tolerant attitude towards visitors and believes there is still a margin for further tourism growth. The study concludes that to ensure sustainable urban tourism, policymakers must implement targeted strategies, including the regulation of short-term rentals and substantial investments in public infrastructure, thereby balancing economic benefits with residents’ quality of life.
