Block voting in the context of "Multi-member plurality"

Single non-transferable vote or SNTV is a multi-winner electoral system in which each voter casts a single vote. Being a semi-proportional parallel to first-past-the-post voting, under SNTV small parties, as well as large parties, have a chance to be represented. Under SNTV, a single party seldom will take all seats in a city or district. SNTV is a combination of multi-member districts and each voter casting just one vote.

SNTV can be considered a variant of dot voting where each voter has only one point to assign. It can also be seen as a variant of limited voting where each elector has one vote, or as a simple version of Single Transferable Voting where votes are not transferred. Unlike block voting or limited voting, where voters can cast multiple votes, under SNTV each voter casts just one.

Plurality block, also called as multiple non-transferable vote, and block plurality voting, is a type of block voting method for multi-winner elections. Each voter may cast as many votes as the number of seats to be filled. The candidates with the most votes are elected. The usual result when the candidates divide into parties is that the most-popular party in the district sees its full slate of candidates elected, even if the party does not have support of majority of the voters.

The term plurality at-large is in common usage in elections for representative members of a body who are elected or appointed to represent the whole membership of the body (for example, a city, state or province, nation or country, club or association). (The plurality at-large election system is common in cities. The Senate of the Philippines is elected by the rare country-wide use of block voting.) Where the system is used in a territory divided into multi-member electoral districts, the system is commonly referred to as "block voting" or the "bloc vote". These systems are usually based on a single round of voting.

The general ticket or party block voting (PBV), is a type of block voting in which voters opt for a party or a team of candidates, and the highest-polling party/team becomes the winner and receives 100% of the seats for this multi-member district. The party block voting is usually applied with more than one multi-member district to prevent one team winning all seats. This system has a winner-take-all nature similar to first-past-the-post voting for single-member districts, which is vulnerable to gerrymandering and majority reversals.

A related system is the majority bonus system, where a block of seats is awarded according to the winner of party-list proportional representation.
