The concept of political participation refers to involvement by people in activities that relate, directly or indirectly, to the political system. These activities can be done individually or collectively. Their purpose can be seeking to influence the political decision-making or, only, the intention of expressing support for ideas or competing political platforms. Initially, within the framework of empirical political science, the vote in democratic contexts was the only type of participation studied (Milbrath and Goel, 1977). Later, the list of actions identified as mechanisms of political participation was extended. New types and methodological approaches were being added to respond better to this extension of the concept.
