 This encyclopedia entry has three main goals. The first is to provide a general overview of the meaning of political representation, identifying the key components of this concept. The second is to highlight several important advances that have been made by the contemporary literature on political representation. These advances point to new forms of political representation, ones that are not limited to the relationship between formal representatives and their constituents. The third goal is to reveal several persistent problems with theories of political representation and thereby to propose some future areas of research.
