[[Voting theorists]] frequently debate which systems can be called "proportional representation", and consider the levels of proportionality achieved by various systems from "low proportional" to "high proportional". The concept of "proportional representation" can be quantified as a measure of the outcome of an election where there are multiple parties and multiple members are elected, and the representatives are demographically similar to the voting population. It is one of many [[types of representation]] in a [[W:Representative government|representative government]].
