The Hare quota (also known as the simple quota) is a formula used under some forms of proportional representation. In these voting systems the quota is the number of votes that guarantees a candidate, or a party in some cases, captures a seat. The Hare quota is the total number of votes divided by the number of seats to be filled. This is the simplest quota, but the Droop quota is mostly used currently. The Hare quota can be used in the single transferable vote (STV-Hare) system and the largest remainder method (LR-Hare) and other quota rule compatible methods of party-list proportional representation. Both versions are named after the political scientist Thomas Hare, but the largest remainder method in which it is used is also sometimes called the Hare–Niemeyer method (after Horst Niemeyer) or the Hamilton method (after Alexander Hamilton). Formula The Hare quota may be given as: where Total votes = the total valid poll; that is, the number of valid (unspoilt) votes cast in an election. Total seats = the total number of seats to be filled in the election. Use in STV The Hare quota is the simplest quota that can be used in elections held under the STV system. In an STV election a candidate who reaches the quota is elected while any votes a candidate receives above the quota are transferred to another candidate. The Hare quota was devised by Thomas Hare, one of the earliest supporters of STV. In 1868, Henry Richmond Droop (1831–1884) invented the Droop quota as an alternative to the Hare quota, and Droop is now widely used, the Hare quota today being rarely used with STV. Example To see how the Hare quota works in an STV election, imagine an election in which there are 2 seats to be filled and 3 candidates: Andrea, Brad, and Carter. One hundred voters voted, each casting one vote but some with back-up preferences. There are 100 ballots showing preferences as follows: Because there are 100 voters and 2 seats, the Hare quota is: To begin the count the first preferences cast for each candidate are tallied and are as follows: Andrea: 60 Carter: 14 Brad: 26 Andrea has more than 50 votes. She therefore has reached the quota and is declared elected. She has 10 votes more than the quota so these votes are transferred to Carter, as specified on the ballots. The
