The survey was carried out in April but only released last month. It showed that 91% believed social media keeps people informed about current events.
About half, 49%, thought that social media helps people to have more impact on political processes.
This belief was more prevalent among urban residents (57%), mostly men (55%) and the more educated respondents (60%).
Seven out of ten, 71%, however, said that social media was likely to make people believe false news.
