According to a national survey done by the National Center for the Study of the Public Opinion in May 2016, about 76 percent of Bulgarian citizens have not read the country’s Constitution. Half of the respondents do not know when the current Constitution was adopted and nearly 60 percent of respondents do not know their civic rights. One-third of Bulgarian citizens, often aged between 30 and 50 years, believe that changes in the constitution are required. National Assembly President Tsetska Tsacheva commented that reading the Constitution once would hardly make citizens aware of their rights and obligations, and would not give them much knowledge on how institutions of the state operate.
