Subject and purpose of work: The article presents the results of a study which aimed to elicit the opinions of the residents of Polish cities belonging to the Cittaslow Network. Materials and methods: The surveys were conducted among 100 residents from 10 Polish Cittaslow cities. Results: Most of the respondents did not identify the city’s accession to the Cittaslow with the improvement of the quality of their lives. The residents’ opinions concerning the changes that occurred after joining the Network depended on their gender, age and education. Conclusions: The survey results have revealed that the membership of the Cittaslow is strictly promotional. Its main objective is to raise funds from projects that promote the idea of Cittaslow as well as to get a promotion by participating in various international events. The opinions of the inhabitants of Cittaslow cities indicate the lack of significant effects established in relevant documents and strategies.
