In the aftermath of the revolution, Tunisia has faced significant security challenges related to the tense relationship between the security institution and the citizenry, exacerbated by the emergence of terrorist cells. Security has become one of the most widely discussed subjects, talked about by almost all components of society, through mass media and other channels. Although it can be intuited that the public’s sense of insecurity is increasing, there has not been any attempt to measure this trend. The level of trust the public exhibits toward the Security Institutions has similarly remained unquantified. The performance of the security institutions has proved difficult to assess, given the lack of data on security and security perceptions among Tunisians. This project aims to create a permanent framework to observe and assess the public’s sense of insecurity, as well as their perceptions as to the effectiveness and trustworthiness of Tunisia’s security institutions, on a bi-monthly basis.
