The terrorist attacks on European cities in recent years have reconfigured significantly ordinary urban life. They concern the production of urban space, which increasingly integrates the material and symbolic constraints of the counter-terrorism, and situated ordinary practices that experience increased logics of control, and whose regimes of use of space are potentially transformed in relation to the search for a greater feeling of security. From this, we propose that the atmosphere of European cities has changed. We have built a survey to assess these questions. Conducted in early 2022 on a representative sample of 15,000 people from UK, Germany and France, it focuses on ordinary practices and perceptions of urban space and the feeling of security and their relationship to past terrorist attacks, as well as the relationship to the fight against terrorism. This paper will address first the elaboration of the survey, the management of the ethical issues, and the contributions of critical research to such methodologies for the investigation of emotions and experiences of violence and fear. Secondly, the comparative results of this international survey will be presented. They show that the relationship to security issues, as well as the evolution of practices, differs from one country to another, and according to social, territorial profiles. Finally, this paper will question the capacity of such a method to address this theme, as most of atmospheric research is carried out using situated qualitative methodologies.
