Abstract

How can the proportionality of proportional representation (PR) systems be measured? This question has been confused with the question of the so-called «thresholds of representation». This article reviews the history of the discovery of thresholds by political science, attempting to clarify their conceptual foundation and the misapprehensions surrounding them. Their valid use as an electoral system proportionality measure is ruled out, and the notion of thinness (measured by Droop) is proposed for replacing them. The article concludes with possible conceptual contributions that are brought together in a terminological proposal.
