Multi member voting methods, also called multi winner methods, are voting methods which elect multiple people in one election. In the context of multi-member methods, they are defined to be proportional if the [[Hare Quota Criterion]] is satisfied. This is not meant to imply anything about [[Proportional representation|Proportional Representation]]. It is common for several of these voting methods to be combined into a [[Regional System]].
==
[[Block voting|Bloc methods]] find the candidate set with the most support or the most votes overall using the same metric which would be used in a [https://electowiki.org/wiki/Single_Member_system single member system]. The number of seats up for election is determined and the top candidates are elected to fill those seats.
Common examples:
*'''Bloc Approval Voting''': Each voter chooses (no ranking) as many candidates as desired. Only one vote is allowed per candidate. Voters may not vote more than once for any one candidate. Add all the votes. Elect the candidates with the most votes until all positions are filled.
*'''Bloc Score Voting''': Each voter scores all the candidates on a scale with three or more units. Starting the scale at zero is preferable. Add all the scores. Elect the candidates with the highest total score until all positions are filled.
*'''Bloc STAR Voting''': Each voter scores all the candidates on a scale from
*'''[[Cumulative voting
*'''[[Single non-transferable vote]]''': Each voter casts one vote for one candidate in a multi-candidate race for multiple offices
*'''Bloc Plurality Voting''': Each voter chooses as many candidates as there are seats to be elected. Add all the votes. Elect the candidates with the most votes until all positions are filled.

[https://rangevoting.org/QualityMulti.html Optimal] Systems select all winners at once by optimizing a specific desirable metric for proportionality. First a "quality function" or desired outcome is determined, and then an algorithm is used to determine the winner set that best maximizes that outcome. In most systems this is done by permuting to all possible winner sets not a [[

===Pros===
* Improved [[Proportionate representation]]: Each elected representative is responsible for a smaller area and can focus on the specific issues important to the citizens of that region .
* Improved [[Petitioner Accountability]]: Each citizen from that district has a specific representative for local issues who can be held to account. ie issues with traffic/schools/hospitals
===Cons===
All the "best" candidates may be running in one district so when it is won they
