The article is aimed at showing the theoretical model of civic activity understood as a social activity in the context of being a citizen in a democratic state. Humans as social beings take actions as members of their own group and in the interest of other people. In the context of democratic system it is justified to distinguish civic activity as a separate kind of social activity. Theoretical analysis of the presented activity allows to differentiate and describe four forms of it, such as social commitment, social (civic) participation, individual political activity and participation in governing. This model can be used as a benchmark in interdisciplinary research and theoretical as well as empirically-based analyses, which describe the activities of humans realizing social interests.
